Bryan Brattlof 4fb7eb8285 board/ti/am62x-sk/patches/linux: backport linux clock fix
With newer versions of DM or DMSC firmware (>v09.02.07) invalid clock
requests will be NAKed and generate a warning in the kernel logs rather
than being ignored like in previous versions of firmware. This, together
with the linux clk driver assuming that all clock IDs are contiguous,
can generate a significant amount of warnings during boot when many
drivers are being probed.

A fix for this has been merged into Linux (commit: ad3ac13c6ec31)
however the backport to older kernels was missed which unfortunately
affects the current v6.8 kernel.

Manually backport this fix while we're using the v6.8 kernel

Texas Instuments SK-AM62 Test and Development Board

Description
===========

This configuration will build a complete image for the TI SK-AM62
board: https://www.ti.com/tool/SK-AM62.

How to Build
============

Select the default configuration for the target:

$ make ti_am62x_sk_defconfig

Optional: modify the configuration:

$ make menuconfig

IMPORTANT: make sure to use the tiboot3 firmware that match with the TI
K3 SoC boot ROM (tiboot3-am62x-{gp/hs-fs/hs}-*.bin) used on the board.

HS-FS should be the default for all TI AM6x devices but earlier version
of TI starter kit EVMs for AM6x was produced with a GP device.

See further details on e2e Forum [1] :

   "Unfortunately with this transition any existing GP device based AM62x
   (and AM64x) boards will no longer boot with MMC/SD card images generated"

For such existing GP device based AM62x boards, users have to provide the
tiboot3.bin name using BR2_TARGET_TI_K3_R5_LOADER_TIBOOT3_BIN.

Build:

$ make

To copy the resultimg output image file to an SD card use dd:

$ dd if=output/images/sdcard.img of=/dev/sdX bs=1M

How to Run
==========

Insert the SD card into the SK-AM62 board, and power it up through the
USB Type-C connector. The system should come up. You can use a
micro-USB cable to connect to the connector labeled UART to
communicate with the board.
