The DHCOM SoM has two options for supplying ETHRX clock to the DWMAC
block and PHY. Either (1) ETHCK_K generates 50 MHz clock on ETH_CLK
pad for the PHY and the same 50 MHz clock are fed back to ETHRX via
internal eth_clk_fb clock connection OR (2) ETH_CLK is not used at
all, MCO2 generates 50 MHz clock on MCO2 output pad for the PHY and
the same MCO2 clock are fed back into ETHRX via ETH_RX_CLK input pad
using external pad-to-pad connection.
Option (1) has two downsides. ETHCK_K is supplied directly from either
PLL3_Q or PLL4_P, hence the PLL output is limited to exactly 50 MHz and
since the same PLL output is also used to supply SDMMC blocks, the
performance of SD and eMMC access is affected. The second downside is
that using this option, the EMI of the SoM is higher.
Option (2) solves both of those problems, so implement it here. In this
case, the PLL4_P is no longer limited and can be operated faster, at
100 MHz, which improves SDMMC performance (read performance is improved
from ~41 MiB/s to ~57 MiB/s with dd if=/dev/mmcblk1 of=/dev/null bs=64M
count=1). The EMI interference also decreases.

The PWR_MPUCR CSTBYDIS bit is set, therefore the CA cores can never
enter CStandby state and would always end up in CStop state. Clear
the PDDS bit, which indicates the CA cores can enter CStandby state
as it makes little sense to keep it set with CSTBYDIS also set.
This does however fix a problem too. When both PWR_MPUCR and PWR_MCUCR
PDDS bits are set, then the chip enters CStandby state even though the
PWR_MCUCR CSTBYDIS is set. Clearing the PWR_MPUCR PDDS prevents that
from happening.

In case the DHSOM is in suspend state and either reset button is pushed

Avoid this failure by not keeping any Buck regulators enabled during reset,

VDD enabled during reset is ST specific, move this addition to ST specific
SPL board initialization so that it wouldn't affect the DHSOM .

The MVTWSI controller can act either as a master or slave device. When
acting as a master, the FSM is driven by the CPU. As a slave, the FSM is
driven by the bus directly. In what is (apparently) a safety mechanism,
if the bus transitions our FSM in any improper way, the FSM goes to a
"bus error" state (0x00). I could find no documented or experimental way
to get the FSM out of this state, except for a controller reset.
Since U-Boot only uses the MVTWSI controller as a bus master, this
feature only gets in the way: we do not care what happened on the bus
previously as long as the bus is ready for a new transaction. So, when
trying to start a new transaction, check for this state and reset the
controller if necessary.
Note that this should not be confused with the "deblocking" technique
(used by the `i2c reset` command), which involves pulsing SCL repeatedly
if SDA is found to be held low, in an attempt to force the bus back to
an idle state. This patch only resets the controller in case something
else had previously upset it, and (in principle) results in no
externally-observable change in behavior.

On RK3568 most pins have a configurable drive strength of level 0-5 and
some pins level 0-11. When rk3568_set_drive is called with a strength
value above 7 the drv value written to reg may overflow into the write
enable bits, resulting in a bad configuration.
This cause e.g. ethernet PHY on Radxa CM3-IO board not to work after
drive is configured according to the device tree.
Could not get PHY for ethernet@fe010000: addr 0
Level 6-11 can be configured using a second reg for some pins, however
the drv value is reused resulting in lower 6 bits being written to reg.
Input schmitt is configured in 2-bit fields on RK3568 compared to
earlier generation and 2'b10 should be used to enable input schmitt.
Change to use regmap_update_bits with a rmask to fix the overflow issue
and closer match the linux driver. Bit shift the drv value used for the
second reg to configure drive strength level 6-11. Also write correct
values for input schmitt setting.
