2022-07-09drm/mipi-dsi: Make remove callback return voidUwe Kleine-König1-3/+1
All implementations return 0 and the return value of mipi_dsi_drv_remove() is ignored anyhow. So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour.

2020-09-24drm/panel: rm68200: allow using non-continuous dsi clockYannick Fertre1-1/+1
The panel is able to work when dsi clock is non-continuous, thus the system power consumption can be reduced using such feature. Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags.

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.

2019-12-09drm/panel: drop drm_device from drm_panelSam Ravnborg1-1/+1
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(). 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 ); ...
