2020-08-02drm/panel: remove return value of function drm_panel_addBernard Zhao1-1/+3
The function "int drm_panel_add(struct drm_panel *panel)" always returns 0, this return value is meaningless. Also, there is no need to check return value which calls "drm_panel_add and", error branch code will never run.

2020-05-27drm: Nuke mode->vrefreshVille Syrjälä1-1/+0
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 <[email protected]> Cc: Neil Armstrong <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Jonas Karlman <[email protected]> Cc: Jernej Skrabec <[email protected]> Cc: Inki Dae <[email protected]> Cc: Joonyoung Shim <[email protected]> Cc: Seung-Woo Kim <[email protected]> Cc: Kyungmin Park <[email protected]> Cc: Linus Walleij <[email protected]> Cc: CK Hu <[email protected]> Cc: Philipp Zabel <[email protected]> Cc: Ben Skeggs <[email protected]> Cc: Thierry Reding <[email protected]> Cc: Sam Ravnborg <[email protected]> Cc: Jerry Han <[email protected]> Cc: Icenowy Zheng <[email protected]> Cc: Jagan Teki <[email protected]> Cc: Stefan Mavrodiev <[email protected]> Cc: Robert Chiras <[email protected]> Cc: "Guido Günther" <[email protected]> Cc: Purism Kernel Team <[email protected]> Cc: Benjamin Gaignard <[email protected]> Cc: Vincent Abriou <[email protected]> Cc: VMware Graphics <[email protected]> Cc: Thomas Hellstrom <[email protected]> Cc: [email protected] Cc: [email protected] Reviewed-by: Laurent Pinchart <[email protected]> Reviewed-by: Emil Velikov <[email protected]> Reviewed-by: Sam Ravnborg <[email protected]> Acked-by: Linus Walleij <[email protected]> Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2019-12-09drm/panel: drop drm_device from drm_panelSam Ravnborg1-3/+2
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 <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]> Reviewed-by: Linus Walleij <[email protected]> Cc: Thierry Reding <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Sam Ravnborg <[email protected]> Cc: Maarten Lankhorst <[email protected]> Cc: Maxime Ripard <[email protected]> Cc: David Airlie <[email protected]> Cc: Daniel Vetter <[email protected]> Cc: Linus Walleij <[email protected]> Cc: Jagan Teki <[email protected]> Cc: Stefan Mavrodiev <[email protected]> Cc: Robert Chiras <[email protected]> Cc: "Guido Günther" <[email protected]> Cc: Purism Kernel Team <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2019-12-09drm/panel: add drm_connector argument to get_modes()Sam Ravnborg1-2/+2
Today the bridge creates the drm_connector, but that is planned to be moved to the display drivers. To facilitate this, update drm_panel_funcs.get_modes() to take drm_connector as an argument.

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(). The panel drivers have been updated with the following Coccinelle semantic patch, with manual inspection to verify that no call to drm_panel_init() with a single argument still exists. @@ expression panel; expression device; identifier ops; @@ drm_panel_init(&panel + , device, &ops ); ...

2018-09-27drm/panel: Add support for Olimex LCD-OLinuXino panelStefan Mavrodiev1-0/+330
This patch adds Olimex Ltd. LCD-OLinuXino bridge panel driver. The panel is used with different LCDs (currently from 480x272 to 1280x800). A small EEPROM chip is used for identification, which holds some factory data and timing requirements.
