Merge tag 'drm/tegra/for-4.13-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next
drm/tegra: Changes for v4.13-rc1 This starts off with the addition of more documentation for the host1x and DRM drivers and finishes with a slew of fixes and enhancements for the staging IOCTLs as a result of the awesome work done by Dmitry and Erik on the grate reverse-engineering effort. * tag 'drm/tegra/for-4.13-rc1' of git://anongit.freedesktop.org/tegra/linux: gpu: host1x: At first try a non-blocking allocation for the gather copy gpu: host1x: Refactor channel allocation code gpu: host1x: Remove unused host1x_cdma_stop() definition gpu: host1x: Remove unused 'struct host1x_cmdbuf' gpu: host1x: Check waits in the firewall gpu: host1x: Correct swapped arguments in the is_addr_reg() definition gpu: host1x: Forbid unrelated SETCLASS opcode in the firewall gpu: host1x: Forbid RESTART opcode in the firewall gpu: host1x: Forbid relocation address shifting in the firewall gpu: host1x: Do not leak BO's phys address to userspace gpu: host1x: Correct host1x_job_pin() error handling gpu: host1x: Initialize firewall class to the job's one drm/tegra: dc: Disable plane if it is invisible drm/tegra: dc: Apply clipping to the plane drm/tegra: dc: Avoid reset asserts on Tegra20 drm/tegra: Check syncpoint ID in the 'submit' IOCTL drm/tegra: Correct copying of waitchecks and disable them in the 'submit' IOCTL drm/tegra: Check for malformed offsets and sizes in the 'submit' IOCTL drm/tegra: Add driver documentation gpu: host1x: Flesh out kerneldoc
