Subject: [PATCH v3 6/8] arm64: dts: qcom: sa8295p-adp: add max20411
Date: Tue, 23 Jan 2024 20:25:20 -0800	[thread overview]
Message-ID: <20240123-sa8295p-gpu-v3-6-d5b4474c8f33@quicinc.com> (raw)
In-Reply-To: <20240123-sa8295p-gpu-v3-0-d5b4474c8f33@quicinc.com>

From: Bjorn Andersson <andersson@kernel.org>

The SA8295P ADP has a MAX20411 LDO regulator on I2C 12, supplying the
VDD_GFX pads. Enable the bus and add the maxim,max20411 device on the
bus.
