A connector's DPMS mode isn't initialized by default, therefore using a default of 0 (DRM_MODE_DPMS_ON). This can cause problems in that the DRM core won't explicitly turn on a connector because it thinks that it is already on. Signed-off-by: NThierry Reding <treding@nvidia.com>

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.

These seem to show up when building for architectures other than ARM, which I guess will never happen. The reason why the kbuild test bot ran into these was a missing dependency which has hence been fixed. Still it doesn't hurt to fix them anyway.

Use EDID data to determine whether the display supports HDMI or DVI only. The HDMI output used to assume to be connected to HDMI displays, but that broke support for DVI displays that don't understand the interspersed audio/other data. To be on the safe side, default to DVI if no EDID data is available.

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.

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: NThierry Reding <treding@nvidia.com>

The Tegra DRM driver currently uses some infrastructure to defer the DRM core initialization until all required devices have registered. The same infrastructure can potentially be used by any other driver that requires more than a single sub-device of the host1x module. Make the infrastructure more generic and keep only the DRM specific code in the DRM part of the driver. Eventually this will make it easy to move the DRM driver part back to the DRM subsystem.

Rework the address table code for the host1x firewall. The previous implementation allocated a bitfield but didn't check for a valid pointer so it could potentially crash. Instead, embed a static bitmap within the gr2d structure to avoid the allocation and use the Linux bitmap API to reduce code complexity. Don't annotate the driver's .remove() function __exit. Even if built in the driver can be unloaded via sysfs, so .remove() needs to stick around after initialization. Also remove the explicit initialization of the driver's .owner field to THIS_MODULE because that's now handled by the driver core. Furthermore make an error message more consistent with other subdrivers, index the syncpts array for better readability, remove a gratuituous newline and reorder some variable declarations to make the code easier to read.

When userspace removes the active framebuffer using DRM_IOCTL_MODE_RMFB, or explicitly disables the CRTC (by calling drmModeSetCrtc(..., NULL) for example), a NULL framebuffer will be passed to the .set_config() implementation of a CRTC. The drm_crtc_helper_set_config() helper will decide to disable a CRTC when that happens. To do so, it calls drm_crtc_helper_disable(), which in turn will iterate over all encoders and decouple them from their connectors and finally call drm_helper_disable_unused_functions() to clean up and call the .disable() or .dpms() implementation for each encoder. However, at no point during this sequence does it track the DPMS mode of a connector, so it will usually remain on after this. When a connector is enabled again, drm_helper_connector_dpms() will not notice that the DPMS mode actually changed and won't do anything, which causes the connector to stay disabled indefinitely. To prevent this from happening, explicitly set the connector's DPMS mode to off when the CRTC is disabled. That way it reflects the correct state and can be enabled again. This solves an issue observed when terminating an X server running on the xf86-video-modesetting driver. Without this patch, the connector would not be enabled properly and the screen would stay dark. Acked-by: NDavid Airlie <airlied@linux.ie> Signed-off-by: NThierry Reding <treding@nvidia.com>

The conflict in intel_drv.h tripped me up a bit since a patch in dinq moves all the functions around, but another one in drm-next removes a single function. So I'ev figured backing this into a backmerge would be good. i915_dma.c is just adjacent lines changed, nothing nefarious there.
