    Subject[PATCH 2/2] ARM: dts: stm32: correct vcc-supply for eeprom on stm32mp15xx-osd32
    Date
    According to the OSD32MP1 Power System overview[1] the EEPROM is connected to
    the VDD line and not to some single-purpose fixed regulator.
    Set the EEPROM supply according to the diagram to eliminate this parent-less
    regulator.
