      drm/omap: Add dispc_mgr_get_supported_outputs() · 7b9cb5ee
      由 Tomi Valkeinen 提交于 
      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: fix crtc->plane property delegation · 6bdad6cf
      由 Tomi Valkeinen 提交于 
      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.

      drm/omap: increase vblank wait timeout · 61f3c40b
      由 Tomi Valkeinen 提交于 
      omap_crtc_wait_pending() waits until the config changes have been taken
into use, usually at next vblank. The wait-timeout used is 50ms, which
usually is enough, but in some rare cases not.

As time wait-timeout is just a safety measure for cases where something
is broken, we can just as well increase the timeout considerably.

This patch makes the timeout 250ms.

      drm/omap: HDMI: change enable/disable to avoid sync-losts · 4e4b53ce
      由 Tomi Valkeinen 提交于 
      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.

      drm: Pass 'name' to drm_crtc_init_with_planes() · f9882876
      由 Ville Syrjälä 提交于 
      Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

I didn't convert drm_crtc_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.
