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 Reviewed-by: Sascha Hauer --- (no changes since v1) drivers/gpu/drm/rockchip/rockchip_drm_vop2.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_vop2.c b/drivers/gpu/drm/rockchip/rockchip_drm_vop2.c index 312da5783362..57784d0a22a6 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_vop2.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_vop2.c @@ -217,6 +217,8 @@ struct vop2 { struct vop2_win win[]; }; +static const struct regmap_config vop2_regmap_config; + static struct vop2_video_port *to_vop2_video_port(struct drm_crtc *crtc) { return container_of(crtc, struct vop2_video_port, crtc); @@ -883,7 +885,11 @@ static void vop2_enable(struct vop2 *vop2) return; } - regcache_sync(vop2->map); + ret = regmap_reinit_cache(vop2->map, &vop2_regmap_config); + if (ret) { + drm_err(vop2->drm, "failed to reinit cache: %d\n", ret); + return; + } if (vop2->data->soc_id == 3566) vop2_writel(vop2, RK3568_OTP_WIN_EN, 1); @@ -913,8 +919,6 @@ static void vop2_disable(struct vop2 *vop2) pm_runtime_put_sync(vop2->dev); - regcache_mark_dirty(vop2->map); - clk_disable_unprepare(vop2->aclk); clk_disable_unprepare(vop2->hclk); }
