drm/rockchip: vop2: fix rk3588 dp+dsi maxclk verification
From: Heiko Stuebner <heiko.stuebner@...> Date: Sun, 24 Dec 2023 19:31:28 +0100
Commit-Message
The clock is in Hz while the value checked against is in kHz, so actual frequencies will never be able to be below to max value. Fix this by specifying the max-value in Hz too. Fixes: 5a028e8f062f ("drm/rockchip: vop2: Add support for rk3588") Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
