drm/omap: fix fbdev pix format to support all platforms

2015-12-14T08:00:22+00:00

omap_fbdev always creates a framebuffer with ARGB8888 pixel format. On OMAP3 we have VIDEO1 overlay that does not support ARGB8888, and on OMAP2 none of the overlays support ARGB888. This patch changes the omap_fbdev's fb to XRGB8888, which is supported by all platforms. Signed-off-by: Tomi Valkeinen Tested-by: H. Nikolaus Schaller Acked-by: Laurent Pinchart

drm/omap: Use new drm_fb_helper functions

2015-08-06T12:13:03+00:00

Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. v3: - Update error handling for new drm_fb_helper funcs. Check using IS_ERR() instead of checking for NULL.

drm: omapdrm: Remove manual update display support

2015-03-20T12:30:19+00:00

All the manual update display code implements eventually ends up to just calls to omap_connector_flush(), currently implemented as an empty TODO stub. Remove it, the code can always be revived and implemented later if interest in manual update displays becomes a reality. Signed-off-by: Laurent Pinchart

drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03+00:00

Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.

drm: Introduce drm_fb_helper_prepare()

2014-07-08T01:31:28+00:00

To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

drm: Constify struct drm_fb_helper_funcs

drm/omap: fix missing unref to fb's buf object

2014-04-14T09:34:37+00:00

omap_fbdev_create() takes a reference to the fb's gem object with omap_gem_get_paddr(). However, it never releases it with omap_gem_put_paddr(). This patch adds the missing omap_gem_put_paddr() to omap_fbdev_free(). Signed-off-by: Tomi Valkeinen

drm: Drop all the stub gamma_get, gamma_set, load_lut functions from drivers

2013-06-17T09:42:47+00:00

Many of the drivers didn't implement palette/gamma handling, but were forced to provide stubs for the hooks to avoid drm_fb_helper from oopsing. Now that the hooks are optional, we can eliminate all the stubs. Signed-off-by: Ville Syrjälä Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie
