Laurent Pinchart 69a12263f6 drm: omapdrm: Wire up atomic state object scaffolding
Hook up the default .reset(), .atomic_duplicate_state() and
.atomic_free_state() helpers to ensure that state objects are properly
created and destroyed, and call drm_mode_config_reset() at init time to
create the initial state objects.

Framebuffer reference count also gets maintained automatically by the
transitional helpers except for the legacy page flip operation. Maintain
it explicitly there.

Laurent Pinchart 5a35876e28 drm: omapdrm: Remove manual update display support
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.

Tomi Valkeinen 7a16360d56 OMAPDSS: DISPC: remove OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES
DISPC can drive data lines either on rising or falling pixel clock edge,
which can be configured by the user.

Sync lines can also be driven on rising or falling pixel clock edge, but
additionally the HW can be configured to drive the sync lines on
opposite clock edge from the data lines.

This opposite edge setting does not make any sense, as the same effect
can be achieved by just setting the sync lines to be driven on the other
edge compared to the data lines. It feels like some kind of backward
compatibility option, even if all DSS versions seem to have the same
implementation.

To simplify the code and configuration of the signals, and to make the
dispc timings more compatible with what is used on other platforms,
let's just remove the whole opposite-edge support.

The drivers that used OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES setting are
changed so that they use the opposite setting from the data edge.

Make the omapdrm driver use the new HDMI ops when possible.

omapdrm will call set_hdmi_mode (when available) to tell the encoder
driver whether the monitor is a DVI or HDMI monitor, and if it's an HDMI
monitor, omapdrm will call set_hdmi_infoframe to to set the AVI
infoframe.

Tomi Valkeinen d8d789416a OMAPDSS: convert pixel clock to common videomode style
omapdss has its own video-timings struct, but we want to move the common
videomode.

The first step is to change the omapdss's pixelclock unit from kHz to
Hz. Also, omapdss uses "pixel_clock" field name, whereas the common
videomode uses "pixelclock" field name. This patch changes the field
name also, as that makes it easy to spot any non-converted pixel_clock
uses.

Archit Taneja bddabbe174 drm/omap: Make fixed resolution panels work
The omapdrm driver requires omapdss panel drivers to expose ops like detect,
set_timings and check_timings. These can be NULL for fixed panel DPI, DBI, DSI
and SDI drivers. At some places, there are no checks to see if the panel driver
has these ops or not, and that leads to a crash.

The following things are done to make fixed panels work:

- The omap_connector's detect function is modified such that it considers panel
  types which are generally fixed panels as always connected(provided the panel
  driver doesn't have a detect op). Hence, the connector corresponding to these
  panels is always in a 'connected' state.

- If a panel driver doesn't have a check_timings op, assume that it supports the
  mode passed to omap_connector_mode_valid(the 'mode_valid' drm helper function)

- The function omap_encoder_update shouldn't really do anything for fixed
  resolution panels, make sure that it calls set_timings only if the panel
  driver has one.

Rob Clark 8bb0daffb0 drm/omap: move out of staging
Now that the omapdss interface has been reworked so that omapdrm can use
dispc directly, we have been able to fix the remaining functional kms
issues with omapdrm.  And in the mean time the PM sequencing and many
other of that open issues have been solved.  So I think it makes sense
to finally move omapdrm out of staging.
