We have encountered circumstances when a board design does not include
pull-up resistors on the external MDIO buses which are not used. This
leads to the MDIO data line not being pulled-up, thus the MDIO controller
will always see the line as busy.
Without a timeout in the MDIO bus driver, the execution is stuck in an

arm: dts: k3-am65: Fix mmc nodes
Because of fundamental interface issues in am65x pg1, only the
initial sdhci1 node at 25 MHz was added in the u-boot.dtsi
from which both the base-board.dts and r5-base-board.dts
inherit the node. Move the node out to k3-am65-main.dtsi
where it belongs and add the board specific properties
in base-board.dts and r5-base-board.dts
This ensures dts compatibility with the kernel dts in the
base-board.dts and enables the SD card interface at 50 MHz
and High Speed mode
While we are here, also fix the main_mmc0_pins_default
property to be included and inherit from the base-board.dts
instead of the u-boot.dtsi

mmc: am654_sdhci: Add support for software tuning
With the new SW tuning App note[1], a custom tuning algorithm is
required for eMMC HS200, HS400 and SD card UHS modes. The algorithm
involves running through the 32 possible input tap delay values and
sending the appropriate tuning command (CMD19/21) for each of them
to get a fail or pass result for each of the values. Typically, the
range will have a small contiguous failing window. Considering the
tuning range as a circular buffer, the algorithm then sets a final
tuned value directly opposite to the failing window.

fs: fat: usage basename in file_fat_write_at, fat_mkdir
This patch involves no functional change. It is just about code
readability.
Both in file_fat_write_at() and fat_mkdir() the incoming file or directory
path are split into two parts: the parent directory and the base name.
In file_fat_write_at() the value of the variable basename is assigned to
the filename parameter and afterwards the variable filename is used instead
of basename. It is more readable to use the variable basename and leave
filename unchanged.
In fat_mkdir() the base name variable is called directory. This is
confusing. Call it basename like in file_fat_write_at(). This allows to
rename parameter new_directory to directory in the implementation of
fat_mkdir() to match the function declaration.
