    Subject[PATCH 5.9 110/252] ARM: dts: stm32: Keep VDDA LDO1 always on on DHCOM
    Date
    From: Marek Vasut <marex@denx.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.

    Fixes: 34e0c7847dcf ("ARM: dts: stm32: Add DH Electronics DHCOM STM32MP1 SoM and PDK2 board")
