The PADCONFIG_202 register (0x02621328) is affected by the locking
of the RSTMUX8 register (0x02620328), and so cannot be configured
in kernel. This has been confirmed as a hardware bug and affects
all K2G SoCs.
Setup the pinmux for this pin before locking the RSTMUX8 register
to allow the ICSS1 PRU1 Ethernet PHY port to work properly. The
workaround was added only for the K2G-ICE board to configure the
pins needed for the PRUSS Ethernet usecase.

AM64 EVM has EEPROM populated at 0x50. Am64 SK has EEPROM populated at

The ICSSG IP is different between the two AM65x Silicon Revisions SR1.0
and SR2.0, and the ICSSG Ethernet nodes will look different between the
two versions. The Linux kernel uses a separate overlay file for the IDK
board between the two variants. Introduce a runtime check to use a
different overlay for IDK daughter card specifically for SR1.0 silicon.
Code is based on logic from an older patch from Roger Quadros.

The AM65x EVM board can use either the newer SR2.0 or an older SR1.0
SoC. The default board dts file is used for SR2.0 silicons, and the
differences between the two silicon revision variants are handled
through a board-specific overlay file, k3-am654-base-board-sr1.dtbo.
Add logic to detect the silicon revision and apply this overlay while
booting Linux.
NOTE:
The ICSSG nodes are not yet added to U-Boot, and so there are no separate
overlay files to apply for U-Boot from A53 SPL.

In the boot flow of HyperFlash boot mode, initially the clock rate is set
by ROM and the same is used by R5 and A72 SPLs. By default the status of
HyperFlash DT node is disabled, which implies that w.r.t R5 SPL HyperFlash
is disabled and the clocks assigned to it can now be reassigned. In
common/spl/spl_nor.c the images are directly loaded into RAM without
setting the clock. In case of R5 SPL, tispl.bin image is first loaded and
then other devices are probed because of which the clock rate set by ROM
for HyperFlash does not change and image loaded is correct. However, by the
time the A72 SPL starts executing, the clock rate assigned to HyperFlash
gets changed. So, if the clock rate is not set again, the reads from
HyperFlash will be corrupted leading to a broken boot.
Fix this by probing the hbmc-am654 driver using
uclass_get_device_by_driver() which sets the default clock rate before
calling the driver probe, when the state of SW3.1 dip switch on the board
is set to 1. Also, define the function spl_perform_fixups() in case of R5
SPL too, so that status of HyperFlash in tispl.bin image can be set
appropriately for device probe.

commit 6f9d41403a upstream.
It has been observed that setting SERDES0 lane mux to USB prevents USB 2.0
operation on USB0. Setting SERDES0 lane mux to non-USB when USB0 is used in
USB 2.0 only mode solves this issue. However, for USB3.0+2.0 operation this
issue is not present.

The dart6ul has an i2c eeprom at 0x50 which contains, among other
things, the manufacturing/revision/options info of the SoM. This patch
replaces the current checkboard() implementation with a more
exhaustive one based on the content of the eeprom.
Since this code uses the new driver model, some changes were also
required in the DTS to make the nodes related to i2c available before
relocation.
This code was inspired from the supported u-boot code from Variscite
which can be found here:

The current PHY rework does the following things:
1. Configure 125MHz clock
2. Setup the TX clock delay (RX is enabled by default),
3. Setup reserved bits to avoid voltage peak
The clock delays are nowadays already configured by the
PHY driver (in ar803x_delay_config). The code for that
can simply be dropped. The clock speed can also be
configured by the PHY driver by adding the device tree
property "qca,clk-out-frequency".
What is left is setting up the undocumented reserved bits
to avoid the voltage peak problem. I slightly improved its
documentation while updating the board's PHY rework code.
