Subject: [PATCH 19/51] arm64: dts: rockchip: set display regulators to
|
|
always-on on BPI-R2-Pro
|
|
|
|
The gpu power supply needs to stay always on until the issues with power-
|
|
domains not being regulator aware is resolved. Otherwise we run into
|
|
issues where the gpu-regulator gets shut down and we start getting mmu
|
|
faults.
