2020-05-27drm: Nuke mode->vrefreshVille Syrjälä1-3/+1
Get rid of mode->vrefresh and just calculate it on demand. Saves a bit of space and avoids the cached value getting out of sync with reality. Mostly done with cocci, with the following manual fixups: - Remove the now empty loop in drm_helper_probe_single_connector_modes() - Fix __MODE() macro in ch7006_mode.c - Fix DRM_MODE_ARG() macro in drm_modes.h - Remove leftover comment from samsung_s6d16d0_mode - Drop the TODO @@ @@ struct drm_display_mode { ... - int vrefresh; ... }; @@ identifier N; expression E; @@ struct drm_display_mode N = { - .vrefresh = E }; @@ identifier N; expression E; @@ struct drm_display_mode N[...] = { ..., { - .vrefresh = E } ,... }; @@ expression E; @@ { DRM_MODE(...), - .vrefresh = E, } @@ identifier M, R; @@ int drm_mode_vrefresh(const struct drm_display_mode *M) { ... - if (M->vrefresh > 0) - R = M->vrefresh; - else if (...) { ... } ... } @@ struct drm_display_mode *p; expression E; @@ ( - p->vrefresh = E; | - p->vrefresh + drm_mode_vrefresh(p) ) @@ struct drm_display_mode s; expression E; @@ ( - s.vrefresh = E; | - s.vrefresh + drm_mode_vrefresh(&s) ) @@ expression E; @@ - drm_mode_vrefresh(E) ? drm_mode_vrefresh(E) : drm_mode_vrefresh(E) + drm_mode_vrefresh(E) @find_substruct@ identifier X; identifier S; @@ struct X { ... struct drm_display_mode S; ... }; @@ identifier find_substruct.S; expression E; identifier I; @@ { .S = { - .vrefresh = E } } @@ identifier find_substruct.S; identifier find_substruct.X; expression E; identifier I; @@ struct X I[...] = { ..., .S = { - .vrefresh = E } ,... }; v2: Drop TODO v3: Rebase v4: Rebase Cc: Andrzej Hajda <a.hajda@samsung.com> Cc: Neil Armstrong <narmstrong@baylibre.com> Cc: Laurent Pinchart <Laurent.pinchart@ideasonboard.com> Cc: Jonas Karlman <jonas@kwiboo.se> Cc: Jernej Skrabec <jernej.skrabec@siol.net> Cc: Inki Dae <inki.dae@samsung.com> Cc: Joonyoung Shim <jy0922.shim@samsung.com> Cc: Seung-Woo Kim <sw0312.kim@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: CK Hu <ck.hu@mediatek.com> Cc: Philipp Zabel <p.zabel@pengutronix.de> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Jerry Han <hanxu5@huaqin.corp-partner.google.com> Cc: Icenowy Zheng <icenowy@aosc.io> Cc: Jagan Teki <jagan@amarulasolutions.com> Cc: Stefan Mavrodiev <stefan@olimex.com> Cc: Robert Chiras <robert.chiras@nxp.com> Cc: "Guido Günther" <agx@sigxcpu.org> Cc: Purism Kernel Team <kernel@puri.sm> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Vincent Abriou <vincent.abriou@st.com> Cc: VMware Graphics <linux-graphics-maintainer@vmware.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Cc: linux-amlogic@lists.infradead.org Cc: nouveau@lists.freedesktop.org Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200428171940.19552-4-ville.syrjala@linux.intel.com

2019-12-10drm/panel: drop drm_device from drm_panelSam Ravnborg1-3/+3
The panel drivers used drm_panel.drm for two purposes: 1) Argument to drm_mode_duplicate() 2) drm->dev was used in error messages The first usage is replaced with drm_connector.dev - drm_connector is already connected to a drm_device and we have a valid connector The second usage is replaced with drm_panel.dev - this makes drivers more consistent in their dev argument used for dev_err() and friends With these replacements there are no more uses of drm_panel.drm, so it is removed from struct drm_panel. 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 <sam@ravnborg.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Laurent Pinchart <Laurent.pinchart@ideasonboard.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Jagan Teki <jagan@amarulasolutions.com> Cc: Stefan Mavrodiev <stefan@olimex.com> Cc: Robert Chiras <robert.chiras@nxp.com> Cc: "Guido Günther" <agx@sigxcpu.org> Cc: Purism Kernel Team <kernel@puri.sm> Link: https://patchwork.freedesktop.org/patch/msgid/20191207140353.23967-8-sam@ravnborg.org

2019-09-08drm/panel: Add and fill drm_panel type fieldLaurent Pinchart1-1/+2
Add a type field to the drm_panel structure to report the panel type, using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS, eDP, DSI and DPI). This will be used to initialise the corresponding connector type. Update all panel drivers accordingly. The panel-simple driver only specifies the type for the known to be LVDS panels, while all other panels are left as unknown and will be converted on a case-by-case basis as they all need to be carefully reviewed.

2019-08-24drm/panel: Initialise panel dev and funcs through drm_panel_init()Laurent Pinchart1-3/+1
Instead of requiring all drivers to set the dev and funcs fields of drm_panel manually after calling drm_panel_init(), pass the data as arguments to the function. This simplifies the panel drivers, and will help future refactoring when adding new arguments to drm_panel_init().

2019-01-23drm/panel: panel-innolux: set display off in innolux_panel_unprepareHsin-Yi, Wang1-6/+5
Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable() to innolux_panel_unprepare(), so they are consistent with innolux_panel_enable() and innolux_panel_prepare(). This also fixes some mode check and irq timeout issue in MTK dsi code. Since some dsi code (e.g. mtk_dsi) have following call trace: 1. drm_panel_disable(), which calls innolux_panel_disable() 2. switch to cmd mode 3. drm_panel_unprepare(), which calls innolux_panel_unprepare() However, mtk_dsi needs to be in cmd mode to be able to send commands (e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()), so we need these functions to be called after the switch to cmd mode happens, i.e. in innolux_panel_unprepare.

2018-05-18drm/panel: Remove drm_panel_detach() calls from all panel driversJyri Sarha1-1/+0
Remove all drm_panel_detach() calls from all panel drivers and update the kerneldoc for drm_panel_detach(). Setting the connector and drm to NULL when the DRM panel device is going away hardly serves any purpose. Usually the whole memory structure is freed right after the remove call. However, calling the detach function from the master DRM device, and setting the connector pointer to NULL, has the logic of marking the panel again as available for another DRM master to attach. The usual situation would be the same DRM master device binding again.
