fb6f67013e mmc: sunxi: Use DM_GPIO flags to set pull-up
Now that the sunxi_gpio driver handles pull-up/down via the driver
model, pin configuration does not need a platform-specific function.

b2acee4bb0 mmc: fsl_esdhc_imx: set sysctl register for clock initialization
[ fsl_esdhc commit 263ddfc345 ]

The initial clock setting should be through sysctl register only,
while the mmc_set_clock() will call mmc_set_ios() introduce other
configurations like bus width, mode, and so on.

00e0cd7fda mmc: fsl_esdhc_imx: Replace more #ifdefs by if
This builds on the previous patch by converting yet more preprocessor
macros to C ifs. This is split off so that the changes adapted from
Micheal's patch may be clearly distinguished from the ones I have
authored myself.

MMC_SUPPORTS_TUNING should really get a Kconfig conversion. And DM_GPIO
needs some -ENOSYS stubs when it isn't defined.

95d6b74cf8 mmc: fsl_esdhc_imx: clean up bus width configuration code
[ fsl_esdhc commit 07bae1de38 ]

This patch is to clean up bus width setting code.

- For DM_MMC, remove getting "bus-width" from device tree.
  This has been done in mmc_of_parse().

- For non-DM_MMC, move bus width configuration from fsl_esdhc_init()
  to fsl_esdhc_initialize() which is non-DM_MMC specific.
  And fix up bus width configuration to support only 1-bit, 4-bit,
  or 8-bit. Keep using 8-bit if it's not set because many platforms
  use driver without providing max bus width.

- Remove bus_width member from fsl_esdhc_priv structure.

8e5266eefd mmc: stm32_sdmmc2: Add support for probing bus voltage level translator
Add support for testing whether bus voltage level translator is present
and operational. This is useful on systems where the bus voltage level
translator is optional, as the translator can be auto-detected by the
driver and the feedback clock functionality can be disabled if it is
not present.

The translator test sets CMD high to avoid interfering with a card, and
then verifies whether signal set on CK is detected on CKIN. If the signal
is detected, translator is present, otherwise the CKIN feedback clock are
disabled.

faf5d4d53d mmc: mtk-sd: implement waiting for DAT0 line state
With the recent changes on mmc driver, we saw that the boot is ~5 secs
longer compared to v2021.07 on mediatek platforms.

This regression is seen during mmc_init and caused by the following
patch [1].

Indeed since we did not support poll dat0, we fulfilled the condition
of [1] and a delay of 500 ms was added for every __mmc_switch call.

By adding the support of wait_dat0(), we now don't need to mdelay
during mmc_init anymore.

425084610e sunxi: Clean up inclusions of asm/arch/gpio.h
As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.

Some files did not contain any GPIO code at all, so this header was
completely unused.

A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.

The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

According to IC suggest, need to clear the STROBE_DLL_CTRL_RESET
before any setting of STROBE_DLL_CTRL register.

USDHC has register bits(bit[27~20] of register STROBE_DLL_CTRL)
for slave sel value. If this register bits value is 0,  it needs
256 ref_clk cycles to update slave sel value. IC suggest to set
bit[27~20] to 0x4, it only need 4 ref_clk cycle to update slave
sel value. This will short the lock time of slave.

i.MX7ULP B0 will need more time to lock the REF and SLV, so change
to add 5us delay.

f0ab8f9fbe clk: Rename clk_get_by_driver_info()
This is actually a misnomer now, since the phandle info may contain
a driver_info index or a udevice index. Rename it to use the word
'phandle', which seems more accurate. Add a comment while we are here.

Also add a test for this function.

0b508ca821 sunxi: mmc: A20: Fix MMC optimisation
Some SoCs (as seen on A20) seem to misreport the MMC FIFO level if the
FIFO is completely full: the level size reads as zero, but the FIFO_FULL
bit is set. We won't do a single iteration of the read loop in this
case, so will be stuck forever.

Check for this situation and use a safe minimal FIFO size instead when
we hit this case.

This fixes MMC boot on A20 devices after the MMC FIFO optimisation
(9faae5457f).

285edfd782 mmc: fsl_esdhc: remove 1ms sleep in esdhc_send_cmd_common()
Since the beginning of this driver which was initially for the MPC8379
and MPC8536 SoCs, there is this spurious 1ms delay. According to the
comment it should actually be only 8 clock cycles. Esp. during EFI block
transfers, this 1ms add up to a significant delay and slows down EFI
boot.

I couldn't find any mention in the MPC8536 that there should be a delay
of 8 clock cycles between commands. The SD card specification mentions that
the clock has to be left enabled for 8 cycles after a command or
response. But I don't see how this delay will help with this.

Go ahead and just remove it. If there will ever be any regression we can
introduce a compile time flag, but for now I'd like to keep it simple.

In the split off imx driver this delay was also removed in commit
9098682200 ("mmc: fsl_esdhc_imx: remove the 1ms delay before sending
command").
