drm/tegra: dc: Add missing call to drm_vblank_on()

2014-11-13T13:07:50+00:00

When the CRTC is enabled, make sure the VBLANK machinery is enabled.
Failure to do so will cause drm_vblank_get() to not enable the VBLANK on
the CRTC and VBLANK-synchronized page-flips won't work.

While at it, get rid of the legacy drm_vblank_pre_modeset() and
drm_vblank_post_modeset() calls that are replaced by drm_vblank_on()
and drm_vblank_off().

drm/tegra: add MODULE_DEVICE_TABLEs

2014-08-04T08:07:39+00:00

When tegra-drm.ko is built as a module, these MODULE_DEVICE_TABLEs allow
the module to be auto-loaded since the module will match the devices
instantiated from device tree.

(Notes for stable: in 3.14+, just git rm any conflicting file, since they
are added in later kernels. For 3.13 and below, manual merging will be
needed)

drm/tegra: dc - Reset controller on driver remove

2014-08-04T08:07:38+00:00

Since the device will no longer be used, may as well keep it in reset to
potentially save some power and make sure it is in a clean state the
next time it's probed.

drm/tegra: Properly align stride for framebuffers

2014-08-04T08:07:38+00:00

Tegra20 and Tegra30 both required the buffer line stride to be aligned
on 8 byte boundaries. Tegra114 and Tegra124 increased the alignment to
64 bytes. Introduce a parameter to specify the alignment requirements
for each display controller and round up the pitch of newly allocated
framebuffers appropriately.

drm/tegra: Implement more tiling modes

2014-08-04T08:07:34+00:00

Tegra124 supports a block-linear mode in addition to the regular pitch
linear and tiled modes. Add support for these by moving the internal
representation into a structure rather than a simple flag.

drm/tegra: Add hardware cursor support

2014-06-05T21:14:47+00:00

Enable hardware cursor support on Tegra124. Earlier generations support
the hardware cursor to some degree as well, but not in a way that can be
generically exposed.

drm/tegra: Remove host1x drm_bus implementation

2014-06-05T21:14:46+00:00

The DRM core can now cope with drivers that don't have an associated
struct drm_bus, so the host1x implementation is no longer useful.

drm/tegra: dc - Compute shift clock divider in output drivers

2014-06-05T21:09:33+00:00

The shift clock divider is highly dependent on the type of output, so
push computation of it down into the output drivers. The old code used
to work merely by accident.

drm/tegra: dc - Move around shift clock programming

2014-06-05T21:09:32+00:00

Program the shift clock divider in tegra_crtc_setup_clk() since that's
where the divider is computed, so passing it around can be avoided.

drm/tegra: dc - Use proper H/V ref-to-sync values

2014-06-05T21:09:20+00:00

For HDMI compliance both of these values need to be set to 1.
