Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.
This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.
Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.
It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit 69b921acae8a)

The driver correctly handles reading back the value of an output gpio
by reading from the shadow register for output, and from gpdat for
inputs.
Unfortunately, when setting the value of some gpio, we do a RMW cycle
on the gpdat register without taking the shadow register into account,
thus accidentally setting other output gpios (at least those whose
value cannot be read back) to 0 at the same time.
When changing a gpio from input to output, we still need to make sure
it initially has the requested value. So, the procedure is
- update the shadow register
- compute the new gpdir register
- write the bitwise and of the shadow and new gpdir register to gpdat
- write the new gpdir register
Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>
Since some chips don't support reading back the value of output gpios
from the gpdat register, we should not do a RMW cycle (i.e., the
clrbits_be32) on the gpdat register when setting a gpio as input, as
that might accidentally change the value of some other (still
configured as output) gpio.
The extra indirection through mpc8xxx_gpio_set_in() does not help
readability, so just fold the gpdir update into
mpc8xxx_gpio_direction_input().

The pci-host-ecam-generic code assumes that the ECAM is the first PCI
bus in the system to be probed. Therefore, the system-wide bus number
allocated by U-Boot in sequence for it is going to be zero, which
corresponds to the memory-mapped config spaces found within it.
Reuse the logic from other PCI bus drivers, and assume that U-Boot will
allocate bus numbers in sequence for all buses within the current ECAM.
So the base number of the bus needs to be subtracted when indexing the
correct config space.

Some config symbols are found in *almost* every _defconfig file for
Allwinner boards, because those options are actually a platform choice,
and not a per-board decision.
Some of these options are older, some have recently been added.
Move those options to be set for all Allwinner boards in their
respective Kconfig files.
The rationales are as follows:
- NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of
address space only, starting at 1 GB. So it's always one bank.
- SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC
accesses, we don't care about filesystems or partitions in there, so
there is no need to define those symbols at all.
- USE_PREBOOT: We start USB early when a keyboard is configured, using the
preboot env variable, so we need to set this variable.
- SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this
symbol to be set (according to 8d8ee47e03).
- SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa5,
specifying this reduces the latency of the USB keyboard handling, so
this was formerly enabled in config headers for all Allwinner boards.

The R5F subsystem/cluster on K3 SoCs can support both LockStep and

though on Split-mode _only_ devices and as such the System Firmware
does not allow the LockStep mode bit to be configured on such devices.
The current logic in k3_r5f_rproc_configure() fails on Split-mode
devices because of this unconditional programming of the LockStep
mode bit, and results in the probe failure shown during the
"rproc init" step at U-Boot prompt.

The resets for the DSP processors on K3 SoCs are managed through the
Power and Sleep Controller (PSC) module. Each DSP typically has two
resets - a global module reset for powering on the device, and a local
reset that affects only the CPU while allowing access to the other
sub-modules within the DSP processor sub-systems.
The C66x DSPs have two levels of internal RAMs that can be used to
boot from, and the firmware loading into these RAMs require the
local reset to be asserted with the device powered on/enabled using
the module reset. Enhance the K3 DSP remoteproc driver to add support
for loading into the internal RAMs. The local reset is deasserted on
SoC power-on-reset, so logic has to be added in probe in remoteproc
mode to balance the remoteproc state-machine.
Note that the local resets are a no-op on C71x cores, and the hardware
does not supporting loading into its internal RAMs.

The DSP remote processors on K3 SoCs require a boot register to be
programmed with a boot address, and these boot addresses need to be
aligned on certain address boundaries. The current code does not have

checking. Add logic to perform this sanity check within the remoteproc
driver itself to detect these anomalies specifically, and print a
meaningful trace. This avoids the cumbersome debug of root-causing
such failures from the corresponding TI-SCI failure.
The C66x and C71x DSP cores have different alignment needs and are

gpio0 (gpio@5d080000) device, here its power domain device
'lsio_gpio0' is obtained for switching off power. Since the
obtained 'lsio_gpio0' device is removed afterwards, its power
domain is also switched off and here the parent power domain
device 'lsio_power_domain' is optained for switching off the

During this child removal the 'lsio_power_domain' device is

the same child removal is repeated, so we are stuck in an

Before commit 83cfbeb0df ("net: phy: Fix mask so that we can identify

Commit 27c3f70f3b ("net: phy: Increase link up delay in
genphy_update_link()") increased the per-iteration waiting time from
1ms to 50ms, without adjusting the timeout counter. This lead to the
timeout increasing from the typical 4 seconds to over three minutes.
Adjust the timeout counter evaluation by that factor of 50 to bring the
timeout back to the intended value.

Add NC-SI to the usual phy handling. This makes two notable changes:
- Somewhat similar to a fixed phy, phy_connect() will create an NC-SI
phy if CONFIG_PHY_NCSI is defined.
- An early return is added to phy_read() and phy_write() to handle a
case like the NC-SI phy which does not define a bus.

This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.
NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).
This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).
The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

The 4 bit MMC controllers have an internal debounce for the SDCD line
with a debounce delay of 1 second. Therefore, after clocks to the IP are
enabled, software has to wait for this time before it can power on the
controller.
Add a deferred_probe() callback which polls on sdcd for a maximum of 2 seconds
before switching on power to the controller or (in the case of no card)
returning a ENOMEDIUM. This pushes the 1 second wait time to when the
card is actually needed rather than at every probe() making sure that
users who don't insert an SD card in the slot don't have to wait such a
long time.

Currently the ofdata_to_platdata() method calls dev_read_addr_pci(),
which potentially accesses the parent PCI bus. If this happens before
the parent PCI bus is probed the resulting address will be wrong.
This behavior was triggered by commit 82de42fa14 ("dm: core:
Allocate parent data separate from probing parent").
According to a comment in drivers/pci/pci-uclass.c [1] accessing
the PCI parent bus in ofdata_to_platdata() is not allowed, and the
access should be moved to the probe() function.
Move the call to dev_read_addr_pci() and the related handling of the
'addr' value from the ofdata_to_platdata() to its own function,
which is then called from the probe() method.
While moving the code, the comment /* try Processor Local Bus device
first */ was dropped. It was initially added with commit 3db886a5bf
("serial: ns16550: Support ns16550 compatible pci uart devices") and
later made obsolete with commit 33c215af4b ("dm: pci: Add a function
to read a PCI BAR").
[1] Comment in drivers/pci/pci-uclass.c:
"A common cause of this problem is that this function is called in the
ofdata_to_platdata() method of @dev. Accessing the PCI bus in that
method is not allowed, since it has not yet been probed. To fix this,
move that access to the probe() method of @dev instead."

Update the driver to support the device tree and the driver model.
Timings and panel parameters are now loaded from the device tree.
The DM code replaces the am335x_lcdpanel structure with
tilcdc_panel_info taken from the linux kernel, as well the management
of additional parameters not covered in the legacy code. In addition,
the am335x_lcdpanel structure contains parameters and operations that
were probably a requirement of the board for which this driver was
developed and which, however, were not developed in the linux kernel.
All this led to rewrite th DM controller initialization code, except
for the pixel clock setting that is executed in a function created in a
previous patch with code taken from the legacy am335xfb_init.
The patch has been tested on a custom board with u-boot 2018.11-rc2 and

This driver currently performs cache operation before the DMA start,
but does nothing after the DMA completion.
When reading data by DMA, the cache invalidation is needed also after
finishing the DMA transfer. Otherwise, the CPU might read data from
the cache instead of from the main memory when speculative memory read
or memory prefetch occurs.
Instead of calling the cache operation directly, this commit adds
dma_unmap_single(), which performs cache invalidation internally,
but drivers do not need which operation is being run.

The reference manuals for MPC8308 and MPC8309 both say that the
esdhcctl aka DMA Control Register "is implemented as SDHCCR" in the
System configuration registers. Unfortunately, that doesn't mean that
the registers are just mirrors of each other - any write to esdhcctl
is simply ignored. So to actually enable cache snooping, we
unfortunately have to add a little ifdeffery.
There is, naturally, no description of the bit fields of esdhcctl in
the MPC8309 manual, but comparing the description of esdhcctl from the
LS1021A reference manual to the description of the sdhccr in MPC8309,
one also finds that the fields are bit-reversed, so the bit to set is
0x02000000 rather than 0x00000040 - this is also what board_mmc_init()

Cadence sent out an errata report to their customers of this IP.
This errata is not so severe, but the tune request should be sent
twice to avoid the potential issue.
Quote from the report:
Problem Summary
---------------
The IP6116 SD/eMMC PHY design has a timing issue on receive data path.
This issue may lead to an incorrect values of read/write pointers of
the synchronization FIFO. Such a situation can happen at the SDR104
and HS200 tuning procedure when the PHY is requested to change a phase
of sampling clock when moving to the next tuning iteration.
Workarounds
-----------
The following are valid workarounds to resolve the issue:
1. In eMMC mode, software sends tune request twice instead of once at
each iteration. This means that the clock phase is not changed on
the second request so there is no potential for clock instability.
2. In SD mode, software must not use the hardware tuning and instead
perform an almost identical procedure to eMMC, using the HRS34 Tune
Force register.

TPM TEE driver
Various minor sandbox video enhancements
New driver model core utility functions
The commit e8e9715df2 ("regulator: fixed: Modify enable-active-high behavior")
fixed the regulator driver behavior when 'enable-active-high' is defined.
Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member
to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator.
The issue here is that regulator_common_ofdata_to_platdata() is called
_before_ regulator_pre_probe() function in which the 'regulator-boot-on'
property is asserted.
As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name()
called in the former function is not enabling the regulator.
This is problematic for e.g. i.MX ethernet driver, which then tries to
perform initialization without power (and fails).
The solution here is to explicitly enable regulator in regulator_pre_probe()
callback only when 'regulator-boot-on' property is present in device tree.
The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is
requested.

At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.
Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.
U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.
Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be

There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.
However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.

The watchdog timer value was never updated in the hardware by this
driver, so the watchdog triggered on some random stale value that
was left in the hardware. The TI SPRUH37C says, quote:
20.4.3.9 Modifying Timer Count/Load Values and Prescaler Setting
...
After a write access, the load register value and prescaler ratio
registers are updated immediately, but new values are considered
only after the next consecutive counter overflow or after a new
trigger command (the WDT_WTGR register).
This means at least one trigger must happen. The driver probably

However, we still need to take care of stable kernel versions for a while.

Tested-by: Marek Vasut <marex@denx.de> # On SoCFPGA Arria V
On Altera SoCFPGA, upon either cold-boot or power-on reset, the
Denali NAND IP is initialized by the BootROM ; upon warm-reset,
the Denali NAND IP is NOT initialized by BootROM. In fact, upon
warm-reset, the SoCFPGA BootROM checks whether the SPL image in
on-chip RAM is valid and if so, completely skips re-loading the
SPL from the boot media.
This does sometimes lead to problems where the software left
the boot media in inconsistent state before warm-reset, and
because the BootROM does not reset the boot media, the boot
media is left in this inconsistent state, often until another
component attempts to access the boot media and fails with an
difficult to debug failure. To mitigate this problem, the SPL
on Altera SoCFPGA always resets all the IPs on the SoC early
on boot.
This results in a couple of register values, pre-programmed by
the BootROM, to be lost during this reset. To restore correct
operation of the IP on SoCFPGA, these values must be programmed
back into the controller by the driver. Note that on other SoCs
which do not use the HW-controlled bootstrap, more registers
may have to be programmed.
This also aligns the SPL behavior with the full Denali NAND
driver, which sets these values in denali_hw_init().

In the RK3399 DRAM driver, the function set_ds_odt() supports operating
in two different modes, selected by the ctl_phy_reg argument: when true,
the function reads and writes directly from the DRAM registers, accessed
through "chan->pctl->denali_*"; when false, the function reads and
writes from an array, accessed through "params->pctl_regs.denali_*",
which is written to DRAM registers at a later time.
However, phy_config_io(), which is called by set_ds_odt() to do a subset
of its register operations, operates directly on DRAM registers at all
times. This means that it reads incorrect values (and writes new values
prematurely) when ctl_phy_reg in set_ds_odt() is false. Fix this by
passing in the address of the registers to work with.
This prevents an "Invalid DRV value" error in the SPL debug log and
(presumably) results in a more correct end state. See the following logs

This is a port of the kernel's spi-nxp-fspi driver. It uses the new
spi-mem interface and does not expose the more generic spi-xfer
interface. The source was taken from the v5.3-rc3 tag.
The port was straightforward:
- remove the interrupt handling and the completion by busy polling the
controller
- remove locks
- move the setup of the memory windows into claim_bus()
- move the setup of the speed into set_speed()
- port the device tree bindings from the original fspi_probe() to
ofdata_to_platdata()
There were only some style change fixes, no change in any logic. For
example, there are busy loops where the return code is not handled
correctly, eg. only prints a warning with WARN_ON(). This port
intentionally left most functions unchanged to ease future bugfixes.
This was tested on a custom LS1028A board. Because the LS1028A doesn't
have proper clock framework support, changing the clock speed was not
tested. This also means that it is not possible to change the SPI
speed on LS1028A for now (neither is it possible in the linux driver).

mtk_clk_find_parent_rate is calling clk_get_rate to know the rate

an issue for clock rates big enough to need the full 32 bits to

DLL_PRESENT flag to make sure that DLL related registers are accessed
only where they are present. Also add a separate set_ios_post()

2. The J721e 8 bit instance is not muxed with anything else inside the

This driver assumes that lpuart clock is already enabled before probing
but using DM only lpuart won't be automatically enabled so add
clk_enable() when probing if CONFIG_CLK is defined. If clock is not
found, because DM is not used, let's emit a warning and proceed, because
serial clock could also be already enabled by non DM code. If clock is
found but cna't be enabled then return with error.

The current mpc83xx_clk driver is broken for any board for which
mpc83xx_has_pci() is true, i.e. anything not MPC8308:
When is_clk_valid() reports that MPC83XX_CLK_PCI is valid,
init_all_clks() proceeds to call init_single_clk(), but that doesn't
know about either MPC83XX_CLK_PCI or has any handling of the
TYPE_SCCR_ONOFF mode correctly returned by retrieve_mode(). Hence
init_single_clk() ends up returning -EINVAL, and the whole board hangs
in serial_init().
The quickest fix is to simply pretend that clock is invalid for
all, since nobody can have been relying on it. Adding proper support
seems to be a bit more involved than just handling TYPE_SCCR_ONOFF:
- The power-on-reset value of SCCR[PCICM] is 0, so
mpc83xx_clk_enable() would probably need to be tought to enable the
clock.
- The frequency of PCI_SYNC_OUT is either SYS_CLK_IN or SYS_CLK_IN/2
depending on the CFG_CLKIN_DIV configuration input, but that can't
be read from software, so to properly fill out
->speed[MPC83XX_CLK_PCI] I think one would need guidance from
Kconfig or dtb.

At present when CONFIG_DEBUG_DEVRES is enabled, U-Boot prints log messages

Signed-off-by: Simon Glass <sjg@chromium.org>
At present the clock driver reads its ofdata in the probe() method. This
is not correct although it is often harmless.
However in this case it causes a problem, something like this:
- ast_get_scu() is called (from somewhere) to get the SCI address
- this probes the clock
- first sets up ofdata (which does nothing at present)
- DM marks clock device as active
- DM calls pinctrl
- pinctrl probes and calls ast_get_scu() in ast2500_pinctrl_probe()
- ast_get_scu() probes the clock, but sees it already marked as
probed
- ast_get_scu() accesses the clock's private data, with scu as NULL
- DM calls clock probe function ast2500_clk_probe() which reads scu
By putting the read of scu into the correct method, scu is read as part of
ofdata setup, and everything is OK.
Note: This problem did not matter until now since DM always probed all
parents before reading a child's ofdata. The fact that pinctrl is a child
of clock seems to trigger this strange bug.
