13ea307f79 board: freescale: t208xrdb: add a config option for rev D dts fixups
Under DM, we rely on u-boot's device tree to provide the correct PHY
addresses. The board_fix_fdt callback is intended to be used for
device tree fixups before relocation. Unfortunately, this isn't an
option when booting from flash since the device tree isn't writable
before relocation.

This patch introduces the CONFIG_T2080RDB_REV_D option to signal that a
board revision D or up is the target. The config option is used to set
the correct Aquantia PHY address in the board's u-boot device tree.

Defconfig files with the option enable explicitly are added for
convenience.

connected to MAC1 and MAC2. The second Aquantia PHY is located at a

Fix-up the Linux device tree to update the PHY address for the second
Aquantia PHY on boards revisions D and up. Also rename the PHY node to
reflect the changes.

11eeeef7b0 pg-wcom-ls102xa: fix sys counter frequency
A system clock of 66MHz was chosen for the pg-wcom-ls102xa.
Compared to the Evalboard, this corresponds to a reduction of 1/3.
The system counter clock should have been reduced accordingly,
but that was not the case, so we had a system time that was
1/3 behind the real time.

This patch corrects the system counter clock to
8.333MHz = 66.667MHz / 8.

fd49502d0f km: ls102x: set ethrotate envvar to no
The default behavior in the latest u-boot revisions is to rotate the
active net device to the next available if the requested link is not
established.

For our ls102x based devices this would mean that if active debug net
device is not available, u-boot will rotate and set the next net device
that is one of the estar adapters.
To return from this situation manual action to set correct ethact
adapter will be needed and this can be annoying when working in
debug mode.

Setting ethrotate=no will disable net adapter rotation and will make sure
that the primary adapter is always used.

On ls102x for the complete DDR region of 1GiB memory_regions_post_test
takes approx. 4min and this is too much for production, so this patch
defines only 1MiB region as compromise.

reality this must not always be the case.
It is possible that tsec adapter is used for 100Mbps connection, and in
this case setting 1000Mbps capabilities can lead to some side effects such
longer autoneg process.

In our ls102x designs this problem leads to long autoneg times (> 4 sec)
in case board rgmii link is 100Mbps capable only.
Limiting the rgmii link capabilities provides faster and smoother

ae7020b435 mmc: fsl_esdhc: convert to CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT
For eSDHC, power supply is through peripheral circuit.
Some eSDHC versions have value 0 of the bit but that
does not reflect the truth. 3.3V is common for SD/MMC,
and is supported for all boards with eSDHC in current
u-boot. So, make 3.3V is supported in default in code.
CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT can be enabled if
future board does not support 3.3V.

This is also a fix-up for one previous patch, which converted
to use IS_ENABLED() for CONFIG_SYS_FSL_MMC_HAS_CAPBLT_VS33
that is not a Kconfig option.

493110cc49 clk: k210: Move k210 clock out of its own subdirectory
Now that we have only one clock driver, we don't need to have our own
subdirectory. Move the driver back with the rest of the clock drivers.

The MAINTAINERS for kendryte pinctrl is also fixed since it has always been
wrong.

c29efc157d clk: k210: Remove bypass driver
This driver no longer serves a purpose now that we have moved away from
CCF. Drop it.

df79e2b48b clk: k210: Don't set PLL rates if we are already at the correct rate
This speeds up boot by preventing multiple reconfigurations of the PLLs.

29e3067d91 clk: k210: Re-add support for setting rate
This adds support for setting clock rates, which was left out of the
initial CCF expunging. There are several tricky bits here, mostly related
to the PLLS:

* The PLL's bypass is broken. If the PLL is reconfigured, any child clocks
  will be stopped.
* PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent
  stopping the CPU while we configure PLL0's rate, ACLK is reparented
  to IN0 while PLL0 is disabled.
* PLL1 is the parent of the AISRAM clock. This clock cannot be reparented,
  so we instead just disallow changing PLL1's rate after relocation (when
  we are using the AISRAM).

612a8334cd clk: k210: Implement soc_clk_dump
Since we are no longer using CCF we cannot use the default soc_clk_dump.
Instead, implement our own.
