Subject: [PATCH 15/32] arm64: dts: mediatek: mt7988a-bpi-r4: Add fixed
|
|
regulators for 1v8 and 3v3
|
|
|
|
Add regulator nodes used for mmc to Bananapi R4 board.
|
|
This board has 1 MMC controller used for SDMMC and eMMC where only one can
|
|
be used at one time, selected by hardware switches. SD uses 3v3 for both
|
|
supplies and emmc uses both regulators.
|
|
So defining both regulators in board dts and referencing them in the dt
|
|
overlay.
