Revert "drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume"
This reverts commit b63a553e8f5aa6574eeb535a551817a93c426d8c. regcache_sync will try to reload the configuration in regcache to hardware, but the registers of 4 Cluster windows and Esmart1/2/3 on the upcoming rk3588 can not be set successfully before internal PD power on. Also it's better to keep the hardware register as it is before we really enable it. So let's revert this version, and keep the first version: commit afa965a45e01 ("drm/rockchip: vop2: fix suspend/resume") Signed-off-by: Andy Yan <andy.yan@rock-chips.com> Reviewed-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/20231211115719.1784834-1-andyshrk@163.com
