Subject: [PATCH v3] arm64: dts: qcom: sdm845-xiaomi-beryllium: Add DSI and panel bits
Date: Wed, 10 Feb 2021 13:48:48 +0530 [thread overview]
Message-ID: <1612945128-23174-1-git-send-email-amit.pundir@linaro.org> (raw)
From: Sumit Semwal <sumit.semwal@linaro.org>
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.

---
v3: Addressed Konrad's concerns. Configured labibb regulators
explicitly based on downstream microvolt values. Display
comes up fine with default discharge-resistor-kohms and
soft-start-us properties, so didn't touch them.
Smoke tested on next-20210209.
v2: Rebased to mainline (v5.11-rc6) and fixed build warnings.
