ARM: dts: stm32: Switch DWMAC RMII clock to MCO2 on DHCOM
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.

i2c: mvtwsi: reset controller if stuck in "bus error" state
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.

clk: rockchip: rk3308: Support reading UART rate and clock registers
Add support to read RK3308 registers used to configure UART clocks, and
thus to get UART rate and baudrate. This fixes clock_get_rate returning
error on serial device probing. Moreover, there is no need anymore to
use 'clock-frequency' property for UART nodes in *-u-boot.dtsi files
for all cases where UART is not inited by U-Boot proper or by SPL o by
TPL code but by a preliminary external boot phase (for Rock PI S, UART
is inited by external TPL).
