Subject: [PATCH v3 2/2] arm64: dts: rockchip: Increase VOP clk rate on RK3328
Date: Sat, 8 Feb 2025 09:57:57 +0800 [thread overview]
Message-ID: <20250208015757.27594-3-zhangqing@rock-chips.com> (raw)
In-Reply-To: <20250208015757.27594-1-zhangqing@rock-chips.com>
The VOP on RK3328 needs to run at a higher rate in order to produce
a proper 3840x2160 signal.
Change to use 300MHz for VIO clk and 400MHz for VOP clk.
Fixes: 0f2ddb128fa2 ("arm64: dts: rockchip: Increase VOP clk rate on RK3328")
