[PATCH 2/2] ARM: dts: stm32: correct vcc-supply for eeprom on stm32mp15xx-osd32
From: Leonard Göhrs
Date: Fri Jun 03 2022 - 05:44:53 EST
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.
