2013-10-31drm/tegra: Add support for tiled buffer objectsThierry Reding
The gr2d and gr3d engines work more efficiently on buffers with a tiled memory layout. Allow created buffers to be marked as tiled so that the display controller can scan them out properly.

2013-10-31drm/tegra: Add 3D supportThierry Reding
Initialize and power the 3D unit on Tegra20, Tegra30 and Tegra114 and register a channel with the Tegra DRM driver so that the unit can be used from userspace. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-31drm/tegra: Introduce tegra_drm_submit()Thierry Reding
Command stream submissions are the same across all devices that expose a channel to userspace, so move the code into a generic function. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-31drm/tegra: Add Tegra114 HDMI supportMikko Perttunen
Tegra114 TMDS configuration requires a new peak_current field and the driver current override bit has changed position. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-31drm/tegra: Properly cleanup and zero out resourcesThierry Reding
When the DRM driver is unloaded, all the associated resources must be cleaned up and zeroed out. This is necessary because of the architecture of the Tegra DRM driver, where not all subdrivers are unloaded along with the DRM driver. Therefore device-managed managed won't be freed and memory cannot be assumed to have been cleared (because it hasn't been reallocated using kzalloc()) by the time the DRM driver is reloaded. It is therefore necessary to zero out the structures to prevent strange errors (such as slab corruptions) from occurring. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-31drm/tegra: Move driver to DRM treeThierry Reding
In order to make subsystem-wide changes easier, move the Tegra DRM driver back into the DRM tree. Signed-off-by: Thierry Reding <treding@nvidia.com>

2013-02-25Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds
Pull drm merge from Dave Airlie: "Highlights: - TI LCD controller KMS driver - TI OMAP KMS driver merged from staging - drop gma500 stub driver - the fbcon locking fixes - the vgacon dirty like zebra fix. - open firmware videomode and hdmi common code helpers - major locking rework for kms object handling - pageflip/cursor won't block on polling anymore! - fbcon helper and prime helper cleanups - i915: all over the map, haswell power well enhancements, valleyview macro horrors cleaned up, killing lots of legacy GTT code, - radeon: CS ioctl unification, deprecated UMS support, gpu reset rework, VM fixes - nouveau: reworked thermal code, external dp/tmds encoder support (anx9805), fences sleep instead of polling, - exynos: all over the driver fixes." Lovely conflict in radeon/evergreen_cs.c between commit de0babd60d8d ("drm/radeon: enforce use of radeon_get_ib_value when reading user cmd") and the new changes that modified that evergreen_dma_cs_parse() function. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (508 commits) drm/tilcdc: only build on arm drm/i915: Revert hdmi HDP pin checks drm/tegra: Add list of framebuffers to debugfs drm/tegra: Fix color expansion drm/tegra: Split DC_CMD_STATE_CONTROL register write drm/tegra: Implement page-flipping support drm/tegra: Implement VBLANK support drm/tegra: Implement .mode_set_base() drm/tegra: Add plane support drm/tegra: Remove bogus tegra_framebuffer structure drm: Add consistency check for page-flipping drm/radeon: Use generic HDMI infoframe helpers drm/tegra: Use generic HDMI infoframe helpers drm: Add EDID helper documentation drm: Add HDMI infoframe helpers video: Add generic HDMI infoframe helpers drm: Add some missing forward declarations drm: Move mode tables to drm_edid.c drm: Remove duplicate drm_mode_cea_vic() gma500: Fix n, m1 and m2 clock limits for sdvo and lvds ...
2013-02-22drm/tegra: Add list of framebuffers to debugfsThierry Reding
This list is most useful to inspect whether framebuffer reference counting works as expected. The code is loosely based on the i915 implementation. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Implement page-flipping supportThierry Reding
All the necessary support bits like .mode_set_base() and VBLANK are now available, so page-flipping case easily be implemented on top. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-22drm/tegra: Implement VBLANK supportThierry Reding
Implement support for the VBLANK IOCTL. Note that Tegra is somewhat special in this case because it doesn't use the generic IRQ support provided by the DRM core (DRIVER_HAVE_IRQ) but rather registers one interrupt handler for each display controller. While at it, clean up the way that interrupts are enabled to ensure that the VBLANK interrupt only gets enabled when required. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-01-28ARM: tegra: migrate to new clock codePrashant Gaikwad
Migrate Tegra clock support to drivers/clk/tegra, this involves moving: 1. definition of tegra_cpu_car_ops to clk.c 2. definition of reset functions to clk-peripheral.c 3. change parent of cpu clock. 4. Remove legacy clock initialization. 5. Initialize clocks using DT. 6. Remove all instance of mach/clk.h Signed-off-by: Prashant Gaikwad <pgaikwad@nvidia.com> [swarren: use to_clk_periph_gate().] Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-11-20drm: Add NVIDIA Tegra20 supportThierry Reding
This commit adds a KMS driver for the Tegra20 SoC. This includes basic support for host1x and the two display controllers found on the Tegra20 SoC. Each display controller can drive a separate RGB/LVDS output.
