Subject: [PATCH 5.9 110/252] ARM: dts: stm32: Keep VDDA LDO1 always on on DHCOM

From: Marek Vasut <marex@...x.de>

[ Upstream commit f4c7fa39415da6db1fa0bc26162ac23a0fbae8bb ]

The VDDA LDO1 PMIC output supplies the analog VDDA input of the
STM32MP1 on DHCOM, keep it always on, otherwise there could be
leakage through the SoC.
