b6a6238f04 Revert "dm: pinctrl: Prevent (re-)configuring pins when already done before relocation"
This reverts commit a7f4b4b344.

As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:

1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)

2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).

3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).

As we are very close to release - please revert this commit.

801f1fa442 dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports
dfu, fastbot and other usb gadget commands take the USB port index as a
parameter. Currently this index is assigned in the order of the driver
bindings.
Changing this behavior using the SEQ_ALIAS feature. This option assign to
the device a SEQ number based on its alias (if it exists)

To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing
naming convention: use "usb" for the name of the gadget UCLASS_DRIVER
(same as for the UCLASS_USB).

If no alias is provided, then the index falls back to the order in which
the bindings took place.

eef05fd3ba mmc: bring back partition init for non-DM MMC drivers
Commit d0851c8937 ("blk: Call part_init() in the post_probe() method")
removed the call to part_init() in mmc.c, as this is done by the DM_MMC
framework.
However Allwinner is (still) relying on a non-DM MMC driver, so we are
now missing the implicit partition init, leading to failing MMC accesses
due to the missing partition information.

Bring the call back just for non-DM MMC driver to fix this regression.

600888110d rockchip: rk3399: Add improved pinctrl driver.
The current pinctrl driver for the RK3399 has a range of qulity issues.
E.g. it only implements the .set_state_simple() callback, it
does not parse the available pinctrl information from the DTS
(instead uses hardcoded values), is not flexible enough to cover
devices without 'interrupt' field in the DTS (e.g. PWM),
is not written generic enough to make code reusable among other
rockchip SoCs...

This patch addresses these issues by reimplementing the whole driver
from scratch using the .set_state() callback.
The new implementation covers all featurese of the old code
(i.e. it supports pinmuxing and pullup/pulldown configuration).

This patch has been tested on a RK3399-Q7 SoM (Puma).

Without this change it is possible that Vybrid's NFC driver malloc() call

As a result some fields of struct nfc - in out case mtd->_get_device - are
"pre initialized" with some random values.

On the latter stage of booting, when e.g. somebody calls 'mtdparts default'
the "data abort" is observed when __get_mtd_device() function is called.

da4918acb8 watchdog: imx: add config to disable wdog reset
Add Kconfig option WATCHDOG_RESET_DISABLE to disable watchdog reset
in imx_watchdog driver, so that the watchdog will not be fed in
u-boot if CONFIG_WATCHDOG_RESET_DISABLE is enabled.

005c1cf888 watchdog: driver support for fsl-lsch2
Support watchdog driver for fsl-lsch2. It's disabled in default.
If you want to use it, please enable CONFIG_IMX_WATCHDOG.
Define CONFIG_WATCHDOG_TIMEOUT_MSECS to set watchdog timeout.

94bf34b172 clk: uniphier: add NAND 200MHz clock
The Denali NAND controller IP needs three clocks:

 - clk: controller core clock

 - clk_x: bus interface clock

 - ecc_clk: clock at which ECC circuitry is run

Currently, only the first one (50MHz) is provided.  The rest of the
two clock ports must be connected to the 200MHz clock line.  Add this.

8ccfbfb3e1 mtd: rawnand: denali: optimize timing parameters for data interface
Based on Linux commit 1dfac31a5a63ac04a9b5fbc3f5105a586560f191

This commit improves the ->setup_data_interface() hook.

The denali_setup_data_interface() needs the frequency of clk_x
and the ratio of clk_x / clk.

The latter is currently hardcoded in the driver, like this:

  #define DENALI_CLK_X_MULT       6

The IP datasheet requires that clk_x / clk be 4, 5, or 6.  I just
chose 6 because it is the most defensive value, but it is not optimal.
By getting the clock rate of both "clk" and "clk_x", the driver can
compute the timing values more precisely.

To not break the existing platforms, the fallback value, 50 MHz is
provided.  It is true for all upstreamed platforms.

a13fe7afe9 mtd: rawnand: denali_dt: add more clocks based on IP datasheet
Based on Linux commit 6f1fe97bec349a1fd6c5a8c7c5998d759fe721d5

Currently, denali_dt.c requires a single anonymous clock, but
the Denali User's Guide requires three clocks for this IP:

 - clk: controller core clock

 - clk_x: bus interface clock

 - ecc_clk: clock at which ECC circuitry is run

This commit supports these named clocks to represent the real hardware.

For the backward compatibility, the driver still accepts a single clock
just as before.  The clk_x_rate is taken from the clock driver again if
the named clock "clk_x" is available.  This will happen only for future
DT, hence the existing DT files are not affected.

e17e0ceb83 power: regulator: Return success on attempt to disable an always-on regulator
commit 4f86a724e8 ("power: regulator: denied disable on always-on
regulator") throws an error when requested to disable an always-on
regulator. It is right that an always-on regulator should not be
attempted to be disabled. But at the same time regulator framework
should not return an error when such request is received. Instead
it should just return success without attempting to disable the
specified regulator. This is because the requesting driver will
not have the idea if the regulator is always-on or not. The
requesting driver will always try to enable/disable regulator as
per the required flow. So it is upto regulator framework to not
break such scenarios.

7b4ea2d888 phy: Fix u-boot coruption when fixed-phy is used
When fixed-link phy is used subnode offset is used as phy address. This
number is bigger then space allocated for bus structure (allocated via
mdio_alloc).
bus->phymap[] array has PHY_MAX_ADDR size (32).
That's why writing bus->phymap[addr] where addr is < 0 or > PHY_MAX_ADDR
is causing write to memory which can caused full U-Boot crash.

The patch is checking if address is in correct range.

a7f4b4b344 dm: pinctrl: Prevent (re-)configuring pins when already done before relocation
This commit prevents from re-configuring pins if those were configured
before relocation.

Some pins - like UART or DDR must be setup before relocation
(as they have 'u-boot,dm-pre-reloc' property set in DTS). Without this
change, those pins are re-configured after relocation (pre_reloc_only = 0,
so we do not "continue").
Such behavior may be a problem for DDR PAD configuration, as they might
be already leveled/tuned with original setup).
