From d9ea62566dbda7afb63c790057f3243f51abf771 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Thu, 5 Feb 2015 16:11:37 +0900 Subject: [PATCH] drm/exynos: remove exynos_plane_dpms The exynos_plane_dpms function handles enabled flag of exynos plane and calls internal hw driver callback function for hw overlay on/off. But it causes state disharmory problem currently and is will be obstacle to apply atomic operation later to keep non-standard per-plane dpms state like enabled flag. Let's remove enabled flag, it just stop to recall internal callback function but hw drivers can handle it properly. And call internal callback function directly then we can remove unnecessary exynos_plane_dpms function Signed-off-by: Joonyoung Shim Signed-off-by: Inki Dae --- drivers/gpu/drm/exynos/exynos_drm_plane.c | 33 +++++------------------ drivers/gpu/drm/exynos/exynos_drm_plane.h | 1 - 2 files changed, 6 insertions(+), 28 deletions(-) diff --git a/drivers/gpu/drm/exynos/exynos_drm_plane.c b/drivers/gpu/drm/exynos/exynos_drm_plane.c index 358cff67e5ce..2dfb847d0ce0 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_plane.c +++ b/drivers/gpu/drm/exynos/exynos_drm_plane.c @@ -145,32 +145,6 @@ void exynos_plane_mode_set(struct drm_plane *plane, struct drm_crtc *crtc, exynos_crtc->ops->win_mode_set(exynos_crtc, exynos_plane); } -void exynos_plane_dpms(struct drm_plane *plane, int mode) -{ - struct exynos_drm_plane *exynos_plane = to_exynos_plane(plane); - struct exynos_drm_crtc *exynos_crtc = to_exynos_crtc(plane->crtc); - - if (mode == DRM_MODE_DPMS_ON) { - if (exynos_plane->enabled) - return; - - if (exynos_crtc->ops->win_enable) - exynos_crtc->ops->win_enable(exynos_crtc, - exynos_plane->zpos); - - exynos_plane->enabled = true; - } else { - if (!exynos_plane->enabled) - return; - - if (exynos_crtc->ops->win_disable) - exynos_crtc->ops->win_disable(exynos_crtc, - exynos_plane->zpos); - - exynos_plane->enabled = false; - } -} - int exynos_update_plane(struct drm_plane *plane, struct drm_crtc *crtc, struct drm_framebuffer *fb, int crtc_x, int crtc_y, @@ -199,7 +173,12 @@ exynos_update_plane(struct drm_plane *plane, struct drm_crtc *crtc, static int exynos_disable_plane(struct drm_plane *plane) { - exynos_plane_dpms(plane, DRM_MODE_DPMS_OFF); + struct exynos_drm_plane *exynos_plane = to_exynos_plane(plane); + struct exynos_drm_crtc *exynos_crtc = to_exynos_crtc(plane->crtc); + + if (exynos_crtc->ops->win_disable) + exynos_crtc->ops->win_disable(exynos_crtc, + exynos_plane->zpos); return 0; } diff --git a/drivers/gpu/drm/exynos/exynos_drm_plane.h b/drivers/gpu/drm/exynos/exynos_drm_plane.h index 59d40755095b..9d3c374e7b3e 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_plane.h +++ b/drivers/gpu/drm/exynos/exynos_drm_plane.h @@ -20,7 +20,6 @@ int exynos_update_plane(struct drm_plane *plane, struct drm_crtc *crtc, unsigned int crtc_w, unsigned int crtc_h, uint32_t src_x, uint32_t src_y, uint32_t src_w, uint32_t src_h); -void exynos_plane_dpms(struct drm_plane *plane, int mode); struct drm_plane *exynos_plane_init(struct drm_device *dev, unsigned long possible_crtcs, enum drm_plane_type type); -- 2.39.2
