Subject: [PATCH v7 6/6] arm64: dts: qcom: db820c: Add user LEDs
Date:   Thu, 29 Apr 2021 14:15:17 -0700
Message-Id: <20210429211517.312792-7-bjorn.andersson@linaro.org>

The db820c has 4 "user LEDs", all connected to the PMI8994. The first
three are connected to the three current sinks provided by the TRILED
and the fourth is connected to MPP2.

By utilizing the DTEST bus the MPP is fed the control signal from the
fourth LPG block, providing a consistent interface to the user.
