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.
* tag 'drm/tegra/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux:
drm/tegra: add MODULE_DEVICE_TABLEs
drm/tegra: dc - Reset controller on driver remove
drm/tegra: Properly align stride for framebuffers
drm/tegra: sor - Configure proper sync polarities
drm/tegra: sor - Use bits-per-color from panel
drm/tegra: Make job submission 64-bit safe
drm/tegra: Allow non-authenticated processes to create buffer objects
drm/tegra: Add SET/GET_FLAGS IOCTLs
drm/tegra: Add SET/GET_TILING IOCTLs
drm/tegra: Implement more tiling modes
drm/tegra: dsi - Handle non-continuous clock flag
drm/tegra: sor - missing unlock on error
