Subject: [PATCH v2 01/11] DONOTMERGE: arm64: dts: ti: Add TI TPS65219 PMIC support for AM642 SK board.
Date:   Tue, 26 Jul 2022 12:33:45 +0200
Message-Id: <20220726103355.17684-2-jneanne@baylibre.com>
In-Reply-To: <20220726103355.17684-1-jneanne@baylibre.com>
References: <20220726103355.17684-1-jneanne@baylibre.com>
Precedence: bulk

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.
