drm/tegra: sor: Add HDMI support

2015-08-13T11:49:37+00:00

The SOR1 introduced on Tegra210 supports HDMI 2.0 and DisplayPort. Add HDMI support and name the debugfs node after the type of SOR. The SOR introduced with Tegra124 is known simply as "sor", whereas the additional SOR found on Tegra210 is known as "sor1". Signed-off-by: Thierry Reding

drm/tegra: sor: Add Tegra210 eDP support

2015-08-13T11:49:36+00:00

The SOR found on Tegra210 is very similar to the version found on Tegra124, except that it no longer supports LVDS. Signed-off-by: Thierry Reding

drm/tegra: dsi: Add Tegra210 support

2015-08-13T11:47:45+00:00

The DSI host controller hasn't changed from Tegra132 to Tegra210, but different characterization parameters may be required. Signed-off-by: Thierry Reding

drm/tegra: dsi: Add Tegra132 support

drm/tegra: dsi: Add Tegra124 support

2015-08-13T11:47:44+00:00

The DSI host controller hasn't changed from Tegra114 to Tegra124, but different characterization parameters may be required. Signed-off-by: Thierry Reding

drm/tegra: dc: Reset VBLANK to off

2015-08-13T11:47:40+00:00

Upon driver load, reset the VBLANK machinery to off to reflect the hardware state. Since the ->reset() callback is called from the initial drm_mode_config_reset() call, move the latter after the VBLANK machinery initialization by drm_vblank_init(). Signed-off-by: Thierry Reding

drm/tegra: Use SIMPLE_DEV_PM_OPS

2015-08-13T11:47:24+00:00

Use this macro to reduce some of the boilerplate. Signed-off-by: Thierry Reding

drm/tegra: Allow VBLANK to be disabled

Merge tag 'drm/tegra/for-4.2-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

2015-06-18T02:53:54+00:00

drm/tegra: Changes for v4.2-rc1 This contains a couple of mostly fixes for issues that have crept up in recent versions of linux-next. One issue is that DP AUX transactions of more than 4 bytes will access the wrong FIFO registers and hence become corrupt. Another fix is required to restore functionality of Tegra20 if using the GART. The current code expects the IOMMU aperture to be the complete 4 GiB address space, whereas the GART on Tegra20 only provides a 128 MiB aperture. One more issue with IOMMU support is that on 64-bit ARM, swiotlb is the default IOMMU implementation backing the DMA API. A side-effect of that is that when dma_map_sg() is called to flush caches (yes, this is a bit of a hack, but ARM does not provide a better API), swiotlb will immediately run out of memory because its bounce buffer is too small to make a framebuffer. Finally I've included a mostly cosmetic fix that stores register values in u32 rather than unsigned long to avoid sign-extension issues on 64- bit ARM. This is only a precaution since it hasn't caused any issues (yet). * tag 'drm/tegra/for-4.2-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: dpaux: Registers are 32-bit drm/tegra: gem: Flush pages after allocation drm/tegra: gem: Take into account IOMMU aperture drm/tegra: dpaux: Fix transfers larger than 4 bytes
