Subject: [PATCH v2 1/4] arm64: boot: dts: qcom: sm8150: Add nodes for PMIC based typec detection
Date:   Fri,  9 Oct 2020 01:28:40 -0700
Message-Id: <20201009082843.28503-2-wcheng@codeaurora.org>
In-Reply-To: <20201009082843.28503-1-wcheng@codeaurora.org>
References: <20201009082843.28503-1-wcheng@codeaurora.org>

Precedence: bulk

Introduce required child nodes to enable the PMIC based USB type C driver.
This consits of connector and endpoint nodes to drivers, which manage the
type C mux and the USB role switch.
