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 [thread overview]
Message-ID: <20201009082843.28503-2-wcheng@codeaurora.org> (raw)
In-Reply-To: <20201009082843.28503-1-wcheng@codeaurora.org>
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.
