Add another flag to the DM core which could be assigned to drivers and
which makes those drivers call their remove callbacks last, just before
booting OS and after all the other drivers finished with their remove
callbacks. This is necessary for things like clock drivers, where the
other drivers might depend on the clock driver in their remove callbacks.
Prime example is the mmc subsystem, which can reconfigure a card from HS
mode to slower modes in the remove callback and for that it needs to
reconfigure the controller clock.

The __of_translate_address routine translates an address from the
device tree into a CPU physical address. A note in the description of
the routine explains that the crossing of any level with
since inherited from IBM. This does not happen for Texas Instruments, or
at least for the beaglebone device tree. Without this patch, in fact,
the translation into physical addresses of the registers contained in the
am33xx-clocks.dtsi nodes would not be possible. They all have a parent
with #size-cells = <0>.
The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation
possible even in the case of crossing levels with #size-cells = <0>.
The patch acts conservatively on address translation, except for
removing a check within the of_translate_one function in the
drivers/core/of_addr.c file:
+
ranges = of_get_property(parent, rprop, &rlen);
- if (ranges == NULL && !of_empty_ranges_quirk(parent)) {
- debug("no ranges; cannot translate\n");
- return 1;
- }
if (ranges == NULL || rlen == 0) {
offset = of_read_number(addr, na);
memset(addr, 0, pna * 4);
debug("empty ranges; 1:1 translation\n");
There are two reasons:
1 The function of_empty_ranges_quirk always returns false, invalidating
the following if statement in case of null ranges. Therefore one of
the two checks is useless.
2 The implementation of the of_translate_one function found in the
common/fdt_support.c file has removed this check while keeping the one
about the 1:1 translation.
The patch adds a test and modifies a check for the correctness of an
address in the case of enabling translation also for zero size cells.
The added test checks translations of addresses generated by nodes of
a device tree similar to those you can find in the files am33xx.dtsi
and am33xx-clocks.dtsi for which the patch was created.
The patch was also tested on a beaglebone black board. The addresses
generated for the registers of the loaded drivers are those specified
by the AM335x reference manual.

In the spirit of using the same base name for all of these related macros,

Signed-off-by: Simon Glass <sjg@chromium.org>
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.
In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.
The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.
Rename everything accordingly.

At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.
Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.
Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.

At present there are no SPL unit tests.
Note that there is one wrinkle with these tests. SPL has limited memory
available for allocation. Also malloc_simple does not free memory
(free() is a nop) and running tests repeatedly causes driver-model to
reinit multiple times and allocate memory. Therefore it is not possible
to run more than a few tests at a time. One solution is to increase the
amount of malloc space in sandbox_spl. This is not a problem for pytest,
since it runs each test individually, so for now this is left as is.

This feature set includes a new CPU driver for at91 family, new driver
for PIT64B hardware timer, support for new at91 family SoC named sama7g5
which adds: clock support, including conversion of the clock tree to
CCF; SoC support in mach-at91, pinctrl and mmc drivers update. The
feature set also includes updates for mmc driver and some other minor
fixes and features regarding building without the old Atmel PIT and the
possibility to read a secondary MAC address from a second i2c EEPROM.
Add tests for SCMI reset controllers. A test device driver
sandbox-scmi_devices.c is used to get reset resources, allowing further
resets manipulation.
Change sandbox-smci_agent to emulate 1 reset controller exposed through
an agent. Add DM test scmi_resets to test this reset controller.

Add tests for SCMI clocks. A test device driver sandbox-scmi_devices.c
is used to get clock resources, allowing further clock manipulation.
Change sandbox-smci_agent to emulate 3 clocks exposed through 2 agents.
Add DM test scmi_clocks to test these 3 clocks.
Update DM test sandbox_scmi_agent with load/remove test sequences
factorized by {load|remove}_sandbox_scmi_test_devices() helper functions.

This change introduces SCMI agent uclass to interact with a firmware
using the SCMI protocols [1].
SCMI agent uclass currently supports a single method to request
processing of the SCMI message by an identified server. A SCMI message
is made of a byte payload associated to a protocol ID and a message ID,
all defined by the SCMI specification [1]. On return from process_msg()
method, the caller gets the service response.
SCMI agent uclass defines a post bind generic sequence for all devices.
The sequence binds all the SCMI protocols listed in the FDT for that
SCMI agent device. Currently none, but later change will introduce
protocols.
This change implements a simple sandbox device for the SCMI agent uclass.
The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages.
To prepare for further test support, the sandbox exposes a architecture
function for test application to read the sandbox emulated devices state.
Currently supports 2 SCMI agents, identified by an ID in the FDT device
name. The simplistic DM test does nothing yet.
SCMI agent uclass is designed for platforms that embed a SCMI server in
a firmware hosted somewhere, for example in a companion co-processor or
in the secure world of the executing processor. SCMI protocols allow an
SCMI agent to discover and access external resources as clock, reset
controllers and more. SCMI agent and server communicate following the
SCMI specification [1]. This SCMI agent implementation complies with
the DT bindings defined in the Linux kernel source tree regarding
SCMI agent description since v5.8.

The tests rely on a dummy driver to allocate and initialize the regmaps
and the regmap fields using the managed API. The first test checks if
the regmap config fields like width, reg_offset_shift, range specifiers,
etc work. The second test checks if regmap fields behave properly (mask
and shift are ok) by peeking into the regmap.

To test this function, sandbox CPU must set cpu_platdata.timebase_freq on
bind. It also needs to expose a method to set the current cpu. I also make
some most members of cpu_sandbox_ops static.
On the timer side, the device tree property
sandbox,timebase-frequency-fallback controls whether sandbox_timer_probe
falls back to time_timebase_fallback or to SANDBOX_TIMER_RATE.

Add boolean input argument @no_map to helper function
fdtdec_add_reserved_memory() to add or not "no-map" property
for an added reserved memory node.
Property no-map is used by the Linux kernel to not not map memory
in its static memory mapping. It is needed for example for the|
consistency of system non-cached memory and to prevent speculative
accesses to some firewalled memory.
No functional change. A later change will update to OPTEE library to
add no-map property to OP-TEE reserved memory nodes.

Clock re-parenting is not binding the clock's device to its new
parent device, it only calls the clock's ops->set_parent() API. The
changes in this commit re-parent the clock device to its new parent
so that subsequent operations like clk_get_parent() to point to the
proper parent.

In common clock framework the relation b/w parent and child clocks is
determined based on the udevice parent/child information. A clock
parent could be changed based on devices needs. In case this is happen
the functionalities for clock who's parent is changed are broken. Add
a function that reparent a device. This will be used in clk-uclass.c
to reparent a clock device.

- Add CCF clocks definitions for iMX6Q enet (ETH)
- Several fixes for CCF framework - the most notable is the one, which
adds get_rate helper to clk-mux.c
- Improvements for clk command - better visibility and alignment.
The previous version of the get_rate helper does not work if the mux
clock parent is changed after the probe. This error has not been
detected because this condition has not been tested. The error occurs
because the set_parent helper does not change the parent of the clock
device but only the clock selection register. Since changing the parent
of a probed device can be tricky, the new version of the get_rate helper
provides the rate of the selected clock and not that of the parent.
