2016-03-03drm/omap: convert dss_mgr_ops to use omap_channelTomi Valkeinen
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>
2016-03-03drm/omap: remove use of omapdss_find_mgr_from_display()Tomi Valkeinen
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>
2016-03-03drm/omap: remove crtc->mgr fieldTomi Valkeinen
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>
2016-03-03drm/omap: Add dispc_mgr_get_supported_outputs()Tomi Valkeinen
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.

2016-03-03drm/omap, omapfb: move exported dispc function declarations to omapdrm/omapfbTomi Valkeinen
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>

2016-03-03drm/omap: fix suspend/resume handlingTomi Valkeinen
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>
2016-03-03drm/omap: check if rotation is supported before commitTomi Valkeinen
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(). Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2016-03-03drm/omap: fix crtc->plane property delegationTomi Valkeinen
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>

2016-03-03drm/omap: verify that fb plane pitches are the sameTomi Valkeinen
The DSS hardware uses the same ROW_INC value for both Y and UV planes for NV12 format. This means that the pitches of the Y and UV planes have to match. omapdrm doesn't check this at the moment, and this can lead into a broken NV12 fb on the screen. This patch adds the check.

On OMAP4 and OMAP5 ES1.0 the HDMI_WP_VIDEO_TIMING_H:HSW field is set directly to the HSW value. On later SoCs the field needs to be programmed with the value of HSW-1. Currently the driver always programs the field with the HSW value. Most videomodes seem to work fine with that, but at least low resolution interlaced modes don't work at all.

Condition the mapping based on whether the buffer has been allocated using the DMA mapping API instead and clean up the flags to avoid having to check both flags and GEM object filp field to decide how to process buffers.

2016-03-03HACK: drm/omap: always use blocking DMM fillTomi Valkeinen
The current driver uses non-blocking DMM fill when releasing memory. This gives us a small performance increase as we don't have to wait for the fill operation to finish. However, the driver does not have any error handling for non-blocking fill. In case of an error, the fill operation may silently fail, leading to leaking DMM engines, which may eventually lead to deadlock if we run out of DMM engines. This patch makes the DMM driver always use blocking fills, so that we can catch the errors. A more complex option would be to allow non-blocking fills, and implement proper error handling, but that is left for the future. This patch is a HACK, as the proper fix is to either decide to always use sync fills and remove all the async related code, or fix the async code.

2016-03-03drm/omap: HDMI: change enable/disable to avoid sync-lostsTomi Valkeinen
We occasionally see DISPC sync-lost errors when enabling and disabling HDMI. Sometimes we get only a few, which get handled (ignored) by the driver, but sometimes there's a flood of the errors which doesn't seem to stop. The HW team has root caused this to the order in which HDMI and DISPC are enabled/disabled. Currently we enable HDMI first, and then DISPC, and vice versa when disabling. HW team's suggestion is to do it the other way around. This patch changes the order, but this has two side effects as the pixel clock is produced by HDMI, and the clock is not running when we enable/disable DISPC: * When enabling DISPC first, we don't get vertical sync events * When disabling DISPC last, we don't get FRAMEDONE event At the moment we use both of those to verify that DISPC has been enabled/disabled properly. Thus this patch also needs to change the omapdrm and omapdss which handle the DISPC side.
