[PATCH v2 1/5] arm64: dts: mediatek: asurada: Add display regulators

From: Nícolas F. R. A. Prado
Date: Thu Oct 06 2022 - 17:26:12 EST


Add the regulators present on the Asurada platform that are used to
power the internal and external displays.

Tested-by: Chen-Yu Tsai <wenst@xxxxxxxxxxxx>
Signed-off-by: Nícolas F. R. A. Prado <nfraprado@xxxxxxxxxxxxx>

Changes in v2:
- Added missing vin-supply to regulators
- Removed min/max-microvolt from regulators that are simple switches
