[PATCH -next 0/2] arm64: dts: ti: Fixes for Beagleplay SD

[Vignesh Raghavendra]

Couple of fixups on top of ti-next branch:

The SD supply on Beagle is really coming from PMIC LDO1 even though its
controllable via GPIO, hence fix the DT accordingly, this also means
PMIC regulator drivers need to be built-in to allow SD card rootfs

[PATCH 1/2] arm64: configs: defconfig: Make TPS65219 regulator built-in

[Vignesh Raghavendra]

These regulators control SD card power supply and thus need to be
built-in to support SD card rootfs, which is common for embedded
devkits and EVMs.

Thanks Vignesh, I will do the fixup.

Chatting with Roger offline, also realized that the board circuitry will
need the following change as it is using a 1/3 voltage divider on SoC's
USB1 as well: I will add this fixup while at it.

I have fixed the following to branch ti-k3-dts-next and ti-k3-config-next on [1].
I had to rewrite history a bit here, but anyways..

Thank you!

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.
