Subject: [PATCH 2/2] arm64: dts: rockchip: Add basic dts for RK3308 EVB
Date:   Thu, 17 Oct 2019 11:05:20 +0800
Message-Id: <20191017030520.32420-1-andy.yan@rock-chips.com>
In-Reply-To: <20191017030242.32219-1-andy.yan@rock-chips.com>
References: <20191017030242.32219-1-andy.yan@rock-chips.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This board use uart4 as debug port and arm core voltage
is modulated by pwm.
