Subject[PATCH v2 3/3] arm64: dts: qcom: sdm845-xiaomi-beryllium: enable qcom wled backlight and link to panel
Date
Xiaomi Poco F1 uses the QCOM WLED driver for backlight control.
Enable and link it to the panel to use it.

Signed-off-by: Joel Selvaraj <jo@jsfamily.in>
---
Changes in v2:
- Remove qcom,enabled-strings property as either it or qcom,num-strings
should be present. qcom,num-strings is specified and sufficient.
(Marijn Suijten's Suggestion)
