Subject: arm64: dts: qcom: sdm845-xiaomi-beryllium: Add DSI and panel bits
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0e5a6f27036e93110d3710d489fcc1408a674e62;p=linux.git

arm64: dts: qcom: sdm845-xiaomi-beryllium: Add DSI and panel bits

Enabling the Display panel for beryllium requires DSI
labibb regulators and panel dts nodes to be added.
It is also required to keep some of the regulators as
always-on.
