Global symbols in the kernel should be prefixed by the name
of the subsystem and/or driver to avoid conflicts when all
code is built-in.
In this case, function names like 'hdmi_register' or 'hdmi_set_mode'
are way too generic for an MSM specific DRM driver, so I'm renaming
them all to msm_hdmi_* here.
I also rename a lot of the 'static' symbols along with the global
names for consistency, even though those are relatively harmless;
they might only be slightly confusing when they show up in
backtraces.

We need this for GL_TIMESTAMP queries.
Note: currently only supported on a4xx.. a3xx doesn't have this
always-on counter. I think we could emulate it with the one CP
counter that is available, but for now it is of limited usefulness
on a3xx (since we can't seem to do time-elapsed queries in any sane
way with the existing firmware on a3xx, and if you are trying to do
profiling on a tiler you want time-elapsed). We can add that later
if it becomes useful.

Existing userspace wouldn't get this far, since getparam ioctl would
have failed and it would have bailed out creating a screen/context.
But all the same, we shouldn't let evil or confused userspace cause a

The DSI driver is currently unaware of how the DSI physical data lanes
are mapped to the logical lanes provided by the DSI controller.
Create a DT binding "qcom,data-lane-map" that provides this information
on a given platform.
The MSM DSI controller is restricted in terms of what all mappings
it can support. The lane polarity is fixed for all the lanes, the clock
lanes are fixed, and the data lanes can be swapped among each other only
for a few combinations. Apply these restrictions when we parse the DT
data.

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

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.

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.

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.
