drm/tegra: Changes for v4.4-rc1 Just a couple of minor fixes and cleanups for this cycle. * tag 'drm/tegra/for-4.4-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: dc: Request/free syncpoint at init/exit drm/tegra: fb: Remove gratuituous blank line gpu: host1x: Fix MLOCK's debug info
syncpoints are resources provided by host1x and their lifetime is tied to the host1x device. They are not properly reference counted either, so removing the host1x device before any of its clients causes a use-after- free error. Adding proper reference counting would be a major enterprise so work around it for now by requesting and freeing the syncpoint at init and exit time, respectively. The host1x device is guaranteed to be around at this point. Signed-off-by: Thierry Reding <treding@nvidia.com>
This removes the need to separately track fb changes i915. That will be done as a separate commit, however. Changes since v1: - Add dri-devel to cc. - Fix a check in intel's prepare and cleanup fb to take rotation into account. Changes since v2: - Split out i915 changes to a separate commit.

drm/tegra: Changes for v4.3-rc1 There are a bunch of non-critical fixes here that I've collected over the past few months, but the biggest part is Tegra210 support, in the DC, DSI and SOR/HDMI drivers. Also this finally restores DPMS with atomic mode-setting, something that has been broken since the conversion and which I had originally expected to take far less longer to fix. * tag 'drm/tegra/for-4.3-rc1' of git://anongit.freedesktop.org/tegra/linux: (41 commits) drm/tegra: sor: Add HDMI support drm/tegra: sor: Add Tegra210 eDP support drm/tegra: dc: Implement atomic DPMS drm/tegra: sor: Restore DPMS drm/tegra: dsi: Restore DPMS drm/tegra: hdmi: Restore DPMS drm/tegra: rgb: Restore DPMS drm/tegra: sor: Use DRM debugfs infrastructure for CRC drm/tegra: sor: Write correct head state registers drm/tegra: sor: Constify display mode drm/tegra: sor: Reset the correct debugfs fields drm/tegra: sor: Set minor after debugfs initialization drm/tegra: sor: Provide error messages in probe drm/tegra: sor: Rename registers for consistency drm/tegra: dpaux: Disable interrupt when detached drm/tegra: dpaux: Configure pads as I2C by default drm/tegra: dpaux: Provide error message in probe drm/tegra: dsi: Add Tegra210 support drm/tegra: dsi: Add Tegra132 support drm/tegra: dsi: Add Tegra124 support ...
Move all code into the new canonical ->disable() and ->enable() helper callbacks so that they play extra nice with atomic DPMS. Signed-off-by: Thierry Reding <treding@nvidia.com>
The call to platform_driver_register() will already set up the .owner field, so there's no need to do it explicitly. Signed-off-by: Thierry Reding <treding@nvidia.com>
Record interrupt statistics, such as the number of frames and VBLANKs received and the number of FIFO underflow and overflows. Signed-off-by: Thierry Reding <treding@nvidia.com>
Request a syncpoint for display prior to registering the host1x client. This will ensure that the syncpoint will be acquired when the KMS driver initializes. Signed-off-by: Thierry Reding <treding@nvidia.com>
Blank lines at the end of functions are hideous, so get rid of it. Signed-off-by: Thierry Reding <treding@nvidia.com>
