On OMAP5 the DISPC channels and DSI PLLs are not connected the same way.
LCD2 on OMAP5 cannot use any DSI PLL as a source clock, but LCD3 can use
DSI2's PLL.
This patch fixes dpi_get_dsidev() by adding separate case for OMAP5 to
handle the difference.

Taal panel driver has support to set rotation and mirroring. However,
these features cannot be used without causing tearing, and are never
used. The code is just extra bloat, so let's remove it.

During the initialization of the DSI protocol registers, we always set
the sources of all DSI channels to L4. However, we don't update the
value in the dsi_data, so we may end up with a different value in the
register and in the dsi_data, leading to DSI problems.
This patch fixes the issue by initializing also the channel source in
the dsi_data.

We currently setup both DSI and DISPC related things when the DSI bus is
enabled. There's no need for DISPC related thing at that point, though,
but only later when the video output is enabled.
To make it possible to use the DSI bus before DISPC overlay manager is
selected, this patch moves DSI's DISPC initialization to
dsi_enable_video_output(), from omapdss_dsi_display_enable(). We also
move the selection of DISPC's LCD clock to dsi_enable_video_output.
This way there are no DISPC dependencies until the video output is
enabled.

The DISPC channel used for each output is currently passed in panel
platform data from the board files.
To simplify this, and to make the panel drivers less dependent on OMAP,
this patch changes omapdss to resolve the channel independently. The
channel is resolved based on the OMAP version and, in case of DSI, the
DSI module id. This resolved channel is stored into a new field in
output, dispc_channel.
The few places where dssdev->channel was used are changed to use
output->recommended_channel. After this patch, dssdev->channel is
obsolete.

dss_mgr_wait_for_vsync() uses dssdev->type to find out if the output is
going to VENC, HDMI, or something else. This creates a dependency on
dssdev, which we want to remove. The task is more logically done by
looking at the output to which the overlay manager in question is
connected to.
This patch changes the code to use output->id to find out which kind of
output we use.

The lgphilips panel driver now manages the gpios required to configure the
panel. This was previously done in omap_dss_device's platform_enable/disable
callbacks defined in board files using this panel.
All the board files using this panel now pass the gpio information as platform
data via the panel_generic_dpi_data struct, which is needed by the panel driver
to configure the gpios connected to the panel. Hence, the
platform_enable/disable ops can be safely removed now.

The lgphilips panel driver leaves gpio configurations to the platform_enable
and disable calls in the platform's board file. These should happen in the
panel driver itself.
Use the platform data as defined for generic dpi panels to pass gpio information
to the lgphilips driver.
This will help in removing the need for the panel drivers to have platform
related callbacks.

The generic dpi panel driver leaves gpio configurations to the platform_enable
and disable calls in the platform's board file. These should happen in the
panel driver itself.
Add a generic way of passing gpio information to the generic dpi panel driver
via it's platform_data. This information includes the number of gpios used by
the panel, the gpio number and logic level (active high/low) for each gpio. This
gpio data will be used by the driver to request and configure the gpios required
by the panel.
This will help in removing the need for the panel drivers to have platform
related callbacks.

The omap_dss_device structs's max_backlight_level is used to pass maximum
backlight level for the platform. However, no board file using this panel
populates this field. Therefore, we remove it's usage from the panel driver.

Structs for platform data of omapdss panels are found in headers in the
'include/video/' path. Board files populate these structs with platform
specific values, and the panel driver uses these to configure the panel.
Currently, each panel has it's own header in the above path. Move all the
omapdss panel platform data structs to a single header omap-panel-data.h.
This is useful because:
- All other omapdss panel drivers will be modified to use platform data. This
would lead to a lot of panel headers usable only by omapdss. A lot of these
platform data structs are trivial, and don't really need a separate header.
- Platform data would be eventually removed, and platform information would be
passed via device tree. Therefore, omapdss panel platform data structs are
temporary, and will be easier to remove if they are all in the same header.
- All board files will have to include the same header to configure a panel's
platform data, that makes the board files more consistent.

Rahul Sharma. I have some follow-up cleanups pending, already acked by

- Some prep-work for the crazy no-pch/display-less platform by Ben.
- Some vlv patches, by far not all (Jesse et al).
- Clean up the HDMI/SDVO #define confusion (Paulo)
- gen2-4 vblank fixes from Ville.
- Unclaimed register warning fixes for hsw (Paulo). More still to come ...
- Complete pageflips which have been stuck in a gpu hang, should prevent
stuck gl compositors (Ville).
- pm patches for vt-switchless resume (Jesse). Note that the i915 enabling
is not (yet) included, that took a bit longer to settle. PM patches are
acked by Rafael Wysocki.
- Minor fixlets all over from various people.

random related bits and fixes from various contributors.
- Some rework of our page table format by Aneesh Kumar which fixes a
thing or two and paves the way for THP support. THP itself will
not make it this time around however.
- More Freescale updates, including Altivec support on the new e6500
