Subject: [RFT PATCH] arm64: dts: qcom: sdm850-c630: add missing panel supply
Date: Sat, 17 Jun 2023 19:15:12 +0200	[thread overview]
Message-ID: <20230617171512.286795-1-krzysztof.kozlowski@linaro.org> (raw)

Panel bindings (boe,nv133fhm-n61) require supply which here actually can
be turned on/off via GPIO control:

  sdm850-lenovo-yoga-c630.dtb: panel: 'power-supply' is a required property
