sunxi: pinctrl: Implement pin muxing functions
Implement the operations to get pin and function names, and to set the
mux for a pin. The pin count and pin names are calculated as if each
bank has the maximum number of pins. Function names are simply the index
into a list of { function name, mux value } pairs.
We assume all pins associated with a function use the same mux value for
that function. This is generally true within a group of pins on a single
port, but generally false when some peripheral can be muxed to multiple
ports. For example, A64 UART3 uses mux 3 on port D, and mux 2 on port H.
But all of the port D pins use the same mux value, and so do all of the
port H pins. This applies even when the pins for some function are not
contiguous, and when the lower-numbered mux values are unused. A good
example of both of these cases is SPI0 on most SoCs.
This strategy saves a lot of space (which is especially important for
SPL), but where the mux value for a certain function differs across
ports, it forces us to choose a single port for that function at build
time. Since almost all boards use the default (i.e. reference design)
pin muxes[1], this is unlikely to be a problem.

This patch enables some configs that should be working on the Bob board,
based on what is observed to work on the Kevin board.
The Bob board uses an Embedded DisplayPort panel compatible with the
simple panel and Rockchip eDP drivers. Its backlight is controlled by
the Chromium OS Embedded Controller Pulse Width Modulator. Enable these
for the board.
Also set VIDEO_ROCKCHIP_MAX_{XRES,YRES} to 1280x800, the resolution of
its panel. This had to be done for the Kevin board, but it's untested if
this is actually necessary for Bob.
The Rockchip video driver needs to assert/deassert some resets, so also
enable the reset controller. RESET_ROCKCHIP defaults to y for this board
when DM_RESET=y, so it's enough to set that.
The Bob board has two USB 3.0 Type-C ports and one USB 2.0 Type-A port
on its right side. Enable the configs relevant to USB devices so these
can be used. This is despite a known issue with RK3399 boards where USB
de-init causes a hang, as there is a known workaround.
Some other rk3399-based devices enable support for the SoC's random
number generator in commit a475bef5340c ("configs: rk3399: enable rng on
firefly/rock960/rockpro64"), as it can provide a KASLR seed when booting
using UEFI. Enable it for Bob as well.
The default misc_init_r() for Rockchip boards sets cpuid and ethernet
MAC address based on e-fuse block. A previous patch extends this on Gru
boards to set registers related to SoC IO domains as is necessary on
these boards. Enable this function and configs for it on Bob.
The microSD card slot on this board (and others based on Gru) is
connected to a GPIO controlled regulator (ppvar-sd-card-io), which must
be operable by U-Boot. Enable the relevant config option to allow this.
Bob boards also use the Winbond W25Q64DW SPI flash chip, enable support

Gru-based boards.
The U-Boot GPIO controlled regulator driver only considers the
"enable-gpios" devicetree property, not the singular "enable-gpio" one.
Some devicetree source files have the singular form as they were added
to Linux kernel when it used that form, and imported to U-Boot as is.
Fix one instance of this in the Gru boards' devicetree to the form that
works in U-Boot.
The PWM controlled regulator driver complains that there is no init
voltage set for a regulator it drives, though it's not clear which one.
Set them all to the voltage levels coreboot sets them: 900 mV.
The RK3399 SoC needs to know the voltage level that some supplies
provides, including one fixed 1.8V audio-related regulator. Although
this synchronization is currently statically done in the board init
functions, a not-so-hypothetical driver that does this dynamically would
query the regulator only to get -ENODATA and be confused. Make sure
U-Boot knows this supply is at 1.8V by setting its limits to that.
Most of this is a reapplication of commit 08c85b57a5ec ("rockchip: gru:
Add extra device-tree settings") whose changes were removed during a
sync with Linux at commit 167efc2c7a46 ("arm64: dts: rk3399: Sync
v5.7-rc1 from Linux"). Apply things to rk3399-gru-u-boot.dtsi instead so
they don't get lost again.

The RK3399 SoC needs to know the voltage value provided by some
regulators, which is done by setting relevant register bits. Configure
these the way other RK3399 boards do, but with the same values as are
set in the equivalent code in coreboot.

rockchip: sdhci: Add HS400 Enhanced Strobe support for RK3568
On RK3568, a register bit must be set to enable Enhanced Strobe.
However, it appears that the address of this register may differ from
vendor to vendor and should be read from the underlying MMC IP. Let the
Rockchip SDHCI driver read this address and set the relevant bit when
Enhanced Strobe configuration is requested.
The IP uses a custom mode select value (0x7) for HS400, use that instead
of the common but non-standard SDHCI_CTRL_HS400 value (0x5). Also add
some necessary DLL_STRBIN and DLL_TXCLK configuration for HS400.
Additionally, a bit signifying that the connected hardware is an eMMC
chip must be set to enable Data Strobe for HS400 and HS400ES modes. Also
make the driver set this bit as appropriate.
This is partly ported from Linux's Synopsys DWC MSHC driver which
happens to be the underlying IP. (drivers/mmc/host/sdhci-of-dwcmshc.c in
Linux tree).

On RK3399, a register bit must be set to enable Enhanced Strobe.
Let the Rockchip SDHCI driver set it when Enhanced Strobe configuration
is requested. However, having it set makes the lower-speed modes stop
working and makes reinitialization fail, so let it be unset as needed in
set_control_reg().
This is mostly ported from Linux's Arasan SDHCI driver which happens
to be the underlying IP. (drivers/mmc/host/sdhci-of-arasan.c in Linux
tree).
Delegate setting the Enhanced Strobe configuration to individual drivers
if they set a function for it. Return -ENOTSUPP if they do not, like
what the MMC uclass does.

mmc: xenon_sdhci: remove wait_dat0 SDHCI OP
Generic SDHCI driver received support for checking the busy status by
polling the DAT[0] level instead of waiting for the worst MMC switch time.
Unfortunately, it appears that this does not work for Xenon controllers
despite being a part of the standard SDHCI registers and the Armada 3720
datasheet itself telling that BIT(20) is useful for detecting the DAT[0]
busy signal.
I have tried increasing the timeout value, but I have newer managed to
catch DAT_LEVEL bits change from 0 at all.
This issue appears to hit most if not all SoC-s supported by Xenon driver,
at least A3720, A8040 and CN9130 have non working eMMC currently.
So, until a better solution is found drop the wait_dat0 OP for Xenon.
I was able to only test it on A3720, but it should work for others as well.

mmc: fsl_esdhc_imx: use VENDORSPEC_FRC_SDCLK_ON when necessary
After commit f132aab40327 ("Revert "mmc: fsl_esdhc_imx: use
VENDORSPEC_FRC_SDCLK_ON to control card clock output""), it
involve issue in mmc_switch_voltage(), because of the special
design of usdhc.
For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN,
these are reserved bits(Though RM contain the definition of these bits,
but actually internal IC logic do not implement, already confirm with
IC team). Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the card
clock output. Here is the definition of this bit in RM:
[8] FRC_SDCLK_ON
Force CLK output active
Do not set this bit to 1 unless it is necessary. Also, make sure that
this bit is cleared when uSDHC’s clock is about to be changed (frequency
change, clock source change, or delay chain tuning).
0b - CLK active or inactive is fully controlled by the hardware.
1b - Force CLK active
In default, the FRC_SDCLK_ON is 0. This means, when there is no command
or data transfer on bus, hardware will gate off the card clock. But in
some case, we need the card clock keep on. Take IO voltage 1.8v switch
as example, after IO voltage change to 1.8v, spec require gate off the
card clock for 5ms, and gate on the clock back, once detect the card
clock on, then the card will draw the dat0 to high immediately. If there
is not clock gate off/on behavior, some card will keep the dat0 to low
level. This is the reason we fail in mmc_switch_voltage().
To fix this issue, and concern that this is only the fsl usdhc hardware
design limitation, set the bit FRC_SDCLK_ON in the beginning of the
wait_dat0() and clear it in the end. To make sure the 1.8v IO voltage
switch process align with SD specification.
For standard tuning process, usdhc specification also require the card
clock keep on, so also add these behavior in fsl_esdhc_execute_tuning().

Commit 0934dddc6436 ("arm: a37xx: Update DTS files to version from
upstream Linux kernel") ported Linux's device-tree files for Armada 3720
SOCs. This broke network on Turris MOX, because the SOC's MDIO bus in
U-Boot currently isn't probed via DM as it's own device, but is
registered as part of mvneta's driver, which means that pinctrl
definitions are not parsed for the MDIO bus node. Also mvneta driver
does not consider "phy-handle" property, only "phy".
For now, fix this by adding armada-3720-turris-mox-u-boot.dtsi file
returning the MDIO to how it was defined previously.
A better solution (using proper mvmdio DM driver) is being work on, but
will need testing on various boards, and we need the bug fixed now for
the upcoming release.

spi: dw: Actually mask interrupts
The designware spi driver unconditionally uses polling.
The comment to spi_hw_init() also states that the function should disable
interrupts.
According to the DesignWare DW_apb_ssi Databook, value 0xff in IMR enables
all interrupts. Since we want to mask all interrupts write 0x0 instead.
On the canaan k210 board, pressing the reset button twice to reset the
board will run u-boot. If u-boot boots Linux without having SPI interrupts
masked, Linux will hang as soon as interrupts are enabled, because of an
interrupt storm.
Properly masking the SPI interrupts in u-boot allows us to successfully
boot Linux, even after resetting the board.
