Subject: [PATCH v7 1/6] DONOTMERGE: arm64: dts: ti: Add TI TPS65219 PMIC support for AM642 SK board.

From: Jerome NEANNE <jneanne@...libre.com>

Add support fot the TI Power Management IC TPS65219
on the AM642 SKEVM board.

Needed for driver testing but official board support pending.
TI commitment is required before board upstream kick-off.
