| | * drm/omap: remove extra manager checks on disconnectTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | The DSS output drivers check 'dssdev->manager' in disconnect() functions. This check is not needed as the manager must always be set if the output device was connected. Remove the check. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to remove the 'struct omap_overlay_manager' from omap_dss_device. At the moment that field is used, among some other uses, to see if the omap_dss_device is connected to an overlay manager. To make it possible to remove the 'struct omap_overlay_manager' field, this patch adds 'bool dispc_channel_connected' field to track the connected-or-not status.

| | * drm/omap: convert dss_mgr_ops to use omap_channelTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are removing the use of 'struct omap_overlay_manager' from omapdrm. This patch changes the function pointers in 'dss_mgr_ops' to get 'enum omap_channel' parameter instead of 'struct omap_overlay_manager'. The change is very straightforward, as we still use 'struct omap_overlay_manager' inside the function implementations where needed. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| | * drm/omap: remove use of omapdss_find_mgr_from_display()Tomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to remove uses of 'struct omap_overlay_manager' we need to get rid of using omapdss_find_mgr_from_display() when initializing omapdrm. Instead of using omapdss_find_mgr_from_display() and mgr->id to find the dispc channel used for the given display, we can instead use omapdss_find_output_from_display(), and get the output->dispc_channel from there. We can also remove omapdss_find_mgr_from_display() as it's no longer used. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| | * drm/omap: remove crtc->mgr fieldTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to remove uses of 'struct omap_overlay_manager' from omapdrm, this patch removes the crtc->mgr field. To accomplish that, a new static array is added along the current 'omap_crtcs' static array, which is used to store the output device connected to a crtc. Optimally we'd use the struct omap_crtc to store this information, but at the time when omap_crtc_dss_connect() is called, we don't yet have the omap_crtc instances. This might possibly be fixed later, but for now the static array does the job. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are removing the use of the 'struct omap_overlay_manager' from omapdrm, and one part of that is removing the use of mgr->supported_outputs field. This patch adds dispc_mgr_get_supported_outputs() function which can be used instead of mgr->supported_outputs. omap_crtc.c is changed to use the new function.

| | * drm/omap, omapfb: move exported dispc function declarations to omapdrm/omapfbTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | omapdrm and omapfb still share the same include/video/omapdss.h. We need to change that so that we can proceed with omapdrm work. However, it's not trivial to make separate omapfb and omapdrm versions of omapdss.h, as that file is also included in other places like arch code, audio code and omap_vout code. So we'll do it piece by piece. This patch makes private versions of all the dispc function declarations that are in omapdss.h. For omapdrm we create a new file, drivers/gpu/drm/omapdrm/dss/omapdss.h, which will contain headers meant to be visible outside omapdss. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | * drm/omap: fix suspend/resume handlingTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For legacy reasons omapdss handles system suspend/resume via PM notifier callback, where the driver disables/resumes all the outputs. This doesn't work well with omapdrm. What happens on suspend is that the omapdss disables the displays while omapdrm is still happily continuing its work, possibly waiting for an vsync irq, which will never come if the display output is disabled, leading to timeouts and errors sent to userspace. This patch moves the suspend/resume handling to omapdrm, and the suspend/resume is now done safely inside modeset lock. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
| | * drm/omap: check if rotation is supported before commitTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | omapdrm is missing a check on the validity of the rotation property. This leads to omapdrm possibly trying to use rotation on non-rotateable framebuffer, which causes the overlay setup to fail. This patch adds the necessary check to omap_plane_atomic_check().

| | * drm/omap: fix crtc->plane property delegationTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before universal planes we had to have plane specific properties for the crtc too, as on the hardware level a crtc uses a plane. In other words, e.g. 'zorder' property was added to both planes and crtcs, and omap_crtc.c would delegate the property set/get to the primary plane. However, the delegation was a bit too generic, delegating all property set/get calls to planes. Thus it's possible to set, say, FB_ID, on a crtc, which gets redirected to the primary plane. This is not standard, and shouldn't be allowed. To keep backward compatibility, we still need to redirect the properties we supported earlier for crtcs, namely 'zorder' and 'rotation'. This patch redirects only the allowed properties from crtcs to planes. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DSS hardware uses the same ROW_INC value for both Y and UV planes for NV12 format.
