Subject: [PATCH v2 2/3] Revert "arm64: dts: rockchip: Increase VOP clk rate on RK3328"
Date: Sat, 25 Jan 2025 09:15:44 +0800 [thread overview]
Message-ID: <20250125011545.15547-3-zhangqing@rock-chips.com> (raw)
In-Reply-To: <20250125011545.15547-1-zhangqing@rock-chips.com>
This reverts commit 0f2ddb128fa20f8441d903285632f2c69e90fae1.
Before changing the PLL frequency, in order to avoid overclocking the
child clock, set the child clock to a large div first, and then set the
CLK as required after the PLL is set.
Fixes: 0f2ddb128fa2 ("arm64: dts: rockchip: Increase VOP clk rate on RK3328")
