Subject: [PATCH 4/5] arm64: dts: qcom: msm8916-huawei-g7: Add display regulator
Date: Fri, 14 May 2021 12:43:27 +0200 [thread overview]
Message-ID: <20210514104328.18756-4-stephan@gerhold.net> (raw)
In-Reply-To: <20210514104328.18756-1-stephan@gerhold.net>
The display on the Huawei Ascend G7 is supplied by a TI TPS65132
regulator. The panel needs a driver in mainline first, but the
TPS65132 is already supported in mainline by the tps65132 driver.
