Update the drm_panel infrastructure to support this to simplify the drivers. With this the panel driver just needs to add the following to the probe() function: err = drm_panel_of_backlight(panel); if (err) return err; Then drm_panel will handle all the rest. There is one caveat with the backlight support. If drm_panel_(enable|disable) are called multiple times in row then backlight_(enable|disable) will be called multiple times. The above will happen when a panel drivers unconditionally calls drm_panel_disable() in their shutdown() function, whan the panel is already disabled and then shutdown() is called. Reading the backlight code it seems safe to call the backlight_(enable|disable) several times. v3: - Improve comments, fix grammar (Laurent) - Do not fail in drm_panel_of_backlight() if no DT support (Laurent) - Log if backlight_(enable|disable) fails (Laurent) - Improve drm_panel_of_backlight() docs - Updated changelog with backlight analysis (triggered by Laurent) v2: - Drop test of CONFIG_DRM_PANEL in header-file (Laurent) - do not enable backlight if ->enable() returns an error Signed-off-by: Sam Ravnborg Cc: Thierry Reding Cc: Laurent Pinchart Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Sean Paul Cc: David Airlie Cc: Daniel Vetter Reviewed-by: Laurent Pinchart Reviewed-by: Linus Walleij --- drivers/gpu/drm/drm_panel.c | 58 ++++++++++++++++++++++++++++++++++++- include/drm/drm_panel.h | 25 ++++++++++++++++ 2 files changed, 82 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/drm_panel.c b/drivers/gpu/drm/drm_panel.c index 4ab7229fb22b..c312d5eb214d 100644 --- a/drivers/gpu/drm/drm_panel.c +++ b/drivers/gpu/drm/drm_panel.c @@ -21,11 +21,13 @@ * DEALINGS IN THE SOFTWARE. */ +#include #include #include #include #include +#include static DEFINE_MUTEX(panel_lock); static LIST_HEAD(panel_list); @@ -196,11 +198,20 @@ EXPORT_SYMBOL(drm_panel_unprepare); */ int drm_panel_enable(struct drm_panel *panel) { + int ret = 0; + if (!panel) return -EINVAL; if (panel->funcs && panel->funcs->enable) - return panel->funcs->enable(panel); + ret = panel->funcs->enable(panel); + + if (ret < 0) + return ret; + + ret = backlight_enable(panel->backlight); + if (ret < 0) + DRM_DEV_INFO(panel->dev, "failed to enable backlight: %d\n", ret); return 0; } @@ -218,9 +229,15 @@ EXPORT_SYMBOL(drm_panel_enable); */ int drm_panel_disable(struct drm_panel *panel) { + int ret; + if (!panel) return -EINVAL; + ret = backlight_disable(panel->backlight); + if (ret < 0) + DRM_DEV_INFO(panel->dev, "failed to disable backlight: %d\n", ret); + if (panel->funcs && panel->funcs->disable) return panel->funcs->disable(panel); @@ -289,6 +306,45 @@ struct drm_panel *of_drm_find_panel(const struct device_node *np) EXPORT_SYMBOL(of_drm_find_panel); #endif +#ifdef CONFIG_BACKLIGHT_CLASS_DEVICE +/** + * drm_panel_of_backlight - use backlight device node for backlight + * @panel: DRM panel + * + * Use this function to enable backlight handling if your panel + * uses device tree and has a backlight phandle. + * + * When the panel is enabled backlight will be enabled after a + * successfull call to &drm_panel_funcs.enable() + * + * When the panel is disabled backlight will be disabled before the + * call to &drm_panel_funcs.disable(). + * + * A typical implementation for a panel driver supporting device tree + * will call this function at probe time.

With this change drm_panel_attach() and drm_panel_detach() no longer have any use as they are empty functions. v2: - editorial correction in changelog (Laurent) Signed-off-by: Sam Ravnborg Reviewed-by: Laurent Pinchart Reviewed-by: Linus Walleij Cc: Thierry Reding Cc: Laurent Pinchart Cc: Sam Ravnborg Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: David Airlie Cc: Daniel Vetter Cc: Linus Walleij Cc: Jagan Teki Cc: Stefan Mavrodiev Cc: Robert Chiras Cc: "Guido Günther" Cc: Purism Kernel Team --- drivers/gpu/drm/drm_panel.c | 6 ------ drivers/gpu/drm/panel/panel-arm-versatile.c | 2 +- .../gpu/drm/panel/panel-feiyang-fy07024di26a30d.c | 2 +- drivers/gpu/drm/panel/panel-ilitek-ili9322.c | 15 ++++++++------- drivers/gpu/drm/panel/panel-ilitek-ili9881c.c | 2 +- drivers/gpu/drm/panel/panel-innolux-p079zca.c | 6 +++--- drivers/gpu/drm/panel/panel-jdi-lt070me05000.c | 2 +- .../gpu/drm/panel/panel-kingdisplay-kd097d04.c | 6 +++--- drivers/gpu/drm/panel/panel-lg-lb035q02.c | 2 +- drivers/gpu/drm/panel/panel-lg-lg4573.c | 4 ++-- drivers/gpu/drm/panel/panel-lvds.c | 2 +- drivers/gpu/drm/panel/panel-nec-nl8048hl11.c | 2 +- drivers/gpu/drm/panel/panel-novatek-nt39016.c | 2 +- .../gpu/drm/panel/panel-olimex-lcd-olinuxino.c | 5 ++--- drivers/gpu/drm/panel/panel-orisetech-otm8009a.c | 2 +- .../gpu/drm/panel/panel-osd-osd101t2587-53ts.c | 4 ++-- .../gpu/drm/panel/panel-panasonic-vvx10f034n00.c | 4 ++-- .../gpu/drm/panel/panel-raspberrypi-touchscreen.c | 5 ++--- drivers/gpu/drm/panel/panel-raydium-rm67191.c | 2 +- drivers/gpu/drm/panel/panel-raydium-rm68200.c | 2 +- .../gpu/drm/panel/panel-rocktech-jh057n00900.c | 2 +- drivers/gpu/drm/panel/panel-ronbo-rb070d30.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6d16d0.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6e3ha2.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6e63j0x03.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6e63m0.c | 2 +- drivers/gpu/drm/panel/panel-seiko-43wvf1g.c | 9 ++++----- drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c | 4 ++-- drivers/gpu/drm/panel/panel-sharp-ls037v7dw01.c | 2 +- drivers/gpu/drm/panel/panel-sharp-ls043t1le01.c | 4 ++-- drivers/gpu/drm/panel/panel-simple.c | 15 ++++++--------- drivers/gpu/drm/panel/panel-sitronix-st7701.c | 2 +- drivers/gpu/drm/panel/panel-sitronix-st7789v.c | 4 ++-- drivers/gpu/drm/panel/panel-sony-acx565akm.c | 2 +- drivers/gpu/drm/panel/panel-tpo-td028ttec1.c | 2 +- drivers/gpu/drm/panel/panel-tpo-td043mtea1.c | 2 +- drivers/gpu/drm/panel/panel-tpo-tpg110.c | 2 +- include/drm/drm_panel.h | 7 ------- 38 files changed, 63 insertions(+), 81 deletions(-) diff --git a/drivers/gpu/drm/drm_panel.c b/drivers/gpu/drm/drm_panel.c index 3daebf56dc44..993e40c0d582 100644 --- a/drivers/gpu/drm/drm_panel.c +++ b/drivers/gpu/drm/drm_panel.c @@ -114,11 +114,6 @@ EXPORT_SYMBOL(drm_panel_remove);
