Subject: [PATCH v2 4/4] arm64: dts: rockchip: Add basic dts for RK3308 EVB
Date: Mon, 21 Oct 2019 16:46:57 +0800 [thread overview]
Message-ID: <20191021084657.28629-1-andy.yan@rock-chips.com> (raw)
In-Reply-To: <20191021084437.28279-1-andy.yan@rock-chips.com>
This board use uart4 as debug port and arm core voltage
is modulated by pwm, logic voltage is fixed to 1.05V.
Signed-off-by: Andy Yan <andy.yan@rock-chips.com>
