* drm/tegra: Tightly bind RGB output to DCThierry Reding2013-12-031-4/+7
| | | | | | | | | | | | | Previously the association to a DC was done via the encoder's .crtc field. That has the disadvantage that when an encoder is detached from its CRTC, that field is set to NULL, leading to situations where it is impossible to access the DC registers required by the RGB output. However, the coupling between DC and RGB output is really fixed on Tegra. While they can be detached logically in DRM, the RGB output can rely on the DC's existence.

There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.

| * drm/tegra: hdmi: Enable VDD earlier for hotplug/DDCMikko Perttunen2013-10-311-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The VDD regulator used to be enabled only at tegra_output_hdmi_enable, which is called after a sink is detected. However, the HDMI hotplug pin works by returning the voltage supplied by the VDD pin, so this meant that the hotplug pin was never asserted and the sink was not detected unless the VDD regulator was set to be always on. This patch moves the enable to the tegra_hdmi_init() function to make sure the regulator will get enabled and therefore ensure proper hotplug detection.

| * drm/tegra: Allocate resources at probe timeThierry Reding2013-10-315-27/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the .init() and .exit() functions are executed whenever the DRM driver is loaded or unloaded, care must be taken not to use them for resource allocation. Otherwise deferred probing cannot be used, since the .init() and .exit() are not run at probe time. Similarly the code that frees resources must be run at .remove() time. If it is run from the .exit() function, it can release resources multiple times. To handle this more consistently, rename the tegra_output_parse_dt() function to tegra_output_probe() and introduce tegra_output_remove() which can be used to free output-related resources.

| * drm/tegra: Properly cleanup and zero out resourcesThierry Reding2013-10-313-5/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | Commit ac24c2204a76e5b42aa103bf963ae0eda1b827f3 ("drm/tegra: Use generic HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select statement for that symbol is a nop. Drop it.

| | | | | | | | | This reverts commit 83c0bcb694be31dcd6c04bdd935b96a95a0af548. Lucas pointed out this was a mistake, and I missed the discussion, so just revert it out to save a rebase. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: tegra: program only one window during modesetLucas Stach2012-12-301-2/+1
| | | | | | | | The intention is to program exactly WIN_A, not WIN_A and possibly others. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: tegra: clean out old gem prototypesLucas Stach2012-12-301-18/+0
| | | | | | | | There is no gem.c anymore, those functions are implemented by the drm_cma_helpers now. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: tegra: remove redundant tegra2_tmds_config entryLucas Stach2012-12-301-16/+3
| | | | | | | | | | The 720p and 1080p entries are completely redundant, as we are matching the table entries against <=pclk. Also generalize the comment, as we are using those table entries even when driving other modes than the standard TV ones.

* drm: tegra: protect DC register access with mutexLucas Stach2012-12-302-0/+14
| | | | | | | | | | | Window properties are programmed through a shared aperture and have to happen atomically. Also we do the read-update-write dance on some of the shared regs. To make sure that different functions don't stumble over each other protect the register access with a mutex.

* drm: tegra: don't leave clients host1x member uninitializedLucas Stach2012-12-301-0/+2
| | | | | | | | No real problem for now, as nothing is using this, but leaving it unitialized is asking for trouble later on. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
