- Fixes for booting newer revs of the SoC in the Raspberry Pi 4
- Propagate some firmware DT properties to the loaded DT
- Update the Zero2W upstream DT name
Newer firmware can manage the SDCDIV clock divisor register, allowing
the divisor to scale with the core as necessary.
Leverage this ability if the firmware supports it.

Setting RX flow error handling will stall the channel until descriptors
are available to move RX data. Setting this bit causes issues when
tearing down ethernet DMA channel at the end of TFTP transfer as
unrelated network packets can cause teardown to stall indefinitely waiting
for driver to queue add more desc leading to channel hang with error
logs:
udma_stop_dev2mem TIMEOUT !
udma_stop_dev2mem: peer not stopped TIMEOUT !
udma_stop_dev2mem TIMEOUT !
Fix this by clearing rx_error_handling similar to how its done for UDMA
as part of udma_alloc_rchan_sci_req()
This fixes occasional TFTP Failures seen when downloading multiple files
one after the other on AM64/AM62 SoCs.

The get_mmc_clk ops is expected to set a clock rate and return the
configured rate as an unsigned value. However, if clk_set_rate fails,
e.g. using a fixed rate clock, a negative error value is returned.
The mmc core will treat this as a valid unsigned rate and tries to
configure a divider based on this bogus clock rate.
Use 0 as the return value when setting clock rate fails, the mmc core
will configure to use bypass mode instead of using a bogus divider.

The CLK_RCAR_GEN3 registers two subdrivers, clk_gen3 and rst_gen3.
The former depends on the clock framework, which is always enabled
in this context of clock framework driver, while the later depends
on reset framework which may not always be enabled.
Ensure the reset framework is also always enabled to prevent inobvious
early boot time bind failure of the CPG driver, which leads to system
showing no activity and is difficult to debug.
Note that one possible approach to debug this is to use CONFIG_DEBUG_UART
and add debug printascii()s into the drivers/clk/renesas/clk-rcar-gen3.c .

The prior stage bootloader might have left the SDnCKCR register in completely
arbitrary state before passing control to U-Boot, which includes the register
being populated with incorrect values. Currently the SDHI driver will attempt
to use clock framework to configure SDn clock, which may fail in case SDnCKCR
contains invalid values for the SDnH clock, because the clock framework would
not be able to determine SDnH clock rate and would get -EINVAL instead, which
in turn would not allow the clock framework to determine the correct SDn clock
divider ratio.
This failure occurs specifically in case SDnCKCR reads back 0x209 .
Correct the problem by first setting default SDnH clock rate to 800 MHz, thus
assuring the SDnCKCR SDnH bits are correct, and only afterward set up the SDn
clock rate to default 200 MHz.
Note that the SDHI driver may reconfigure SDnH clock later based on IOS
settings obtained from the attached card, the 800 MHz set up here is only
the default value.

Currently, pinctrl drivers are getting probed during post-bind, however
that is being reverted, and on A37XX pinctrl driver is the one that
registers the GPIO driver during the probe.
So, if the pinctrl driver doesn't get probed GPIO-s won't get registered
and thus they cannot be used.
This is a problem on the Methode eDPU as it just uses SB pins as GPIO-s
and without them being registered networking won't work as it only has
one SFP slot and the TX disable GPIO is on the SB controller.
So, lets just add a flag only to A37XX driver to probe after binding
in order for the GPIO driver to always get registered.

The RK3288 TRM states that, for 8-bit DDR modes:
The CLKDIV register should always be programmed with a value
higher than zero (0); that is, a clock divider should always be
used for 8-bit DDR mode.
In Linux, the driver applies this logic for all SoCs using the driver
and does not distinguish RK3288, so presumably this requirement is the
same for all other Rockchip SoCs using this IP.
Add the necessary code to double the clock frequency when 8-bit DDR is
selected. The dw_mmc core already handles setting CLKDIV correctly
given the input clock and desired bus clock.
