Subject: [PATCH] arm64: dts: qcom: sdm845-xiaomi-beryllium: Add DSI and panel bits

From: Sumit Semwal <[email protected]>

Enabling the Display panel for beryllium phone (Xiaomi
Pocophone F1) requires DSI labibb regulators and panel
dts nodes to be added. It is also required to keep some
of the regulators as always-on.

Argh.. This patch is not formatted on top of mainline. It doesn't
apply cleanly. Sorry about that. I'll fix that in the next version.
