drm/tegra: Changes for v3.17-rc1

Browse source 
Mostly some cleanup all over the place. Pitch alignment limitations of
 the display controller are now honored and job submission is 64-bit
 safe.
 
 The SOR output (used for eDP) properly configures sync signal polarities
 according to the display mode rather than hard-coding them to some value
 and the number of bits per color is now taken from the panel rather than
 hard-coded to properly support 24-bit vs. 18-bit panels.
 
 The DSI controller now properly supports non-continuous clock mode.
 
 GEM objects can now have their flags and tiling mode modified via IOCTLs
 to allow buffers imported from Nouveau to be properly displayed. Newer
 generations of the Tegra display controller can also detile block linear
 buffers at scan-out time.
 
 Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it
 to be automatically loaded when built as a module.

drm/tegra: Changes for v3.17-rc1

Mostly some cleanup all over the place. Pitch alignment limitations of
the display controller are now honored and job submission is 64-bit
safe.

The SOR output (used for eDP) properly configures sync signal polarities
according to the display mode rather than hard-coding them to some value
and the number of bits per color is now taken from the panel rather than
hard-coded to properly support 24-bit vs. 18-bit panels.

The DSI controller now properly supports non-continuous clock mode.

GEM objects can now have their flags and tiling mode modified via IOCTLs
to allow buffers imported from Nouveau to be properly displayed. Newer
generations of the Tegra display controller can also detile block linear
buffers at scan-out time.

Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it
to be automatically loaded when built as a module.
