* drm/panel: remove return value of function drm_panel_addBernard Zhao2020-08-021-1/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* drm/panel: Add and fill drm_panel type fieldLaurent Pinchart2019-09-081-1/+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.

* drm/panel: Add a driver for the TPO TPG110Linus Walleij2019-01-111-0/+496
The TPO (Toppoly) TPG110 is a pretty generic display driver similar in vein to the Ilitek 93xx devices. It is not a panel per se but a driver used with several low-cost noname panels. This is used on the Nomadik NHK15 combined with a OSD OSD057VA01CT display for WVGA 800x480. The driver is pretty minimalistic right now but can be extended to handle non-default polarities, gamma correction etc. The driver is based on the baked-in code in drivers/video/fbdev/amba-clcd-nomadik.c which will be decomissioned once this us upstream.
