[PATCH 1/4] arm64: dts: ti: k3-am64-tqma64xxl: add supply regulator for I2C devices

[Matthias Schiffer]

Describes the hardware better, and avoids a few warnings during boot:

    lm75 0-004a: supply vs not found, using dummy regulator
    at24 0-0050: supply vcc not found, using dummy regulator
    at24 0-0054: supply vcc not found, using dummy regulator

[PATCH 2/4] arm64: dts: ti: k3-am64-tqma64xxl-mbax4xxl: add muxing for GPIOs on pin headers

[Matthias Schiffer]

The pin headers X41 and X42 do not have a fixed function. All of these
pins can be assigned to PRG0, but as a default, it makes more sense to
configure them as simple GPIOs, as the MBaX4XxL is a starterkit/evaluation
mainboard.

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.
