Subject: [PATCH 1/3] arm64: boot: dts: qcom: sm8150: Add nodes for PMIC based typec detection
Date:   Thu, 30 Jul 2020 21:57:10 -0700
Message-Id: <20200731045712.28495-2-wcheng@codeaurora.org>
In-Reply-To: <20200731045712.28495-1-wcheng@codeaurora.org>
References: <20200731045712.28495-1-wcheng@codeaurora.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.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.
