[PATCH 00/10] arm64: dts: ti: k3-am64: Add missing properties used in u-boot

[Nishanth Menon]

Hi,

while attempting to cleanup u-boot, I noticed that u-boot had some
additional nodes that were'nt in kernel.org, and this makes syncing the
kernel.org patches back to u-boot hard.

So, sync the same.

Bootlogs: (SK and evm)
https://gist.github.com/nmenon/6b09f55251225d3f3cce076c32a33bba

Baseline: next-20230413 (will be great if we can get into rc2 - will
make u-boot sync easier)

[PATCH 01/10] arm64: dts: ti: k3-am64: Add general purpose timers

[Nishanth Menon]

There are 11 general purpose timers on am64 that can be used for things
like PWM using pwm-omap-dmtimer driver. There are also additional four
timers in the MCU domain that do not have interrupts routable for Linux.

We configure the timers with the 25 MHz input clock by default as the
32.768 kHz clock may not be wired on the device. We leave the MCU domain
timers clock mux unconfigured, and mark the MCU domain timers reserved.
The MCU domain timers are likely reserved by the software for the ESM
module.

Compared to am65, the timers on am64 do not have a dedicated IO mux for
the timers. On am62, the timers have different interrupts, clocks and
power domains compared to am65, and the MCU timers are at a different
IO address. Compared to AM62, the AM64 times have different clocks and
count in main domain are different as well.

[PATCH 06/10] arm64: dts: ti: k3-am642-evm: Enable main_i2c0 and eeprom

[Nishanth Menon]

Enable AT24CM01 on the base board using the corresponding compatible.

Note:
checkpatch does a simple pattern search and fails to find a match
#47: FILE: arch/arm64/boot/dts/ti/k3-am642-evm.dts:353:

But, Documentation/devicetree/bindings/eeprom/at24.yaml
              - items:
                  pattern: cs1024$
Cleanly covers the same and dtbs_check looks clean.

[PATCH 10/10] arm64: dts: ti: k3-am642-sk|evm: Drop bootargs, add aliases

[Nishanth Menon]

Drop bootargs and add aliases based on base pinout of SK as per [1] and
evm per [2].

Indices chosen attempt to maintain some level of consistency with
existing aliases.

While at this, drop a extra EoL. While this patch could be split, it
seems trivial to add additional cleanup steps.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
