Subject: [PATCH v2] arm64: dts: qcom: sdm845-xiaomi-beryllium: Add DSI and panel bits
Date: Thu,  4 Feb 2021 13:39:37 +0530	[thread overview]
Message-ID: <1612426177-6611-1-git-send-email-amit.pundir@linaro.org> (raw)

From: Sumit Semwal <sumit.semwal@linaro.org>

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.
