Merge tag 'drm-for-v4.11-less-shouty' of git://people.freedesktop.org/~airlied/linux

Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.11. Nothing too major, the tinydrm and mmu-less support should make writing smaller drivers easier for some of the simpler platforms, and there are a bunch of documentation updates. Intel grew displayport MST audio support which is hopefully useful to people, and FBC is on by default for GEN9+ (so people know where to look for regressions). AMDGPU has a lot of fixes that would like new firmware files installed for some GPUs. Other than that it's pretty scattered all over. I may have a follow up pull request as I know BenH has a bunch of AST rework and fixes and I'd like to get those in once they've been tested by AST, and I've got at least one pull request I'm just trying to get the author to fix up. Core: - drm_mm reworked - Connector list locking and iterators - Documentation updates - Format handling rework - MMU-less support for fbdev helpers - drm_crtc_from_index helper - Core CRC API - Remove drm_framebuffer_unregister_private - Debugfs cleanup - EDID/Infoframe fixes - Release callback - Tinydrm support (smaller drivers for simple hw) panel: - Add support for some new simple panels i915: - FBC by default for gen9+ - Shared dpll cleanups and docs - GEN8 powerdomain cleanup - DMC support on GLK - DP MST audio support - HuC loading support - GVT init ordering fixes - GVT IOMMU workaround fix amdgpu/radeon: - Power/clockgating improvements - Preliminary SR-IOV support - TTM buffer priority and eviction fixes - SI DPM quirks removed due to firmware fixes - Powerplay improvements - VCE/UVD powergating fixes - Cleanup SI GFX code to match CI/VI - Support for > 2 displays on 3/5 crtc asics - SI headless fixes nouveau: - Rework securre boot code in prep for GP10x secure boot - Channel recovery improvements - Initial power budget code - MMU rework preperation vmwgfx: - Bunch of fixes and cleanups exynos: - Runtime PM support for MIC driver - Cleanups to use atomic helpers - UHD Support for TM2/TM2E boards - Trigger mode fix for Rinato board etnaviv: - Shader performance fix - Command stream validator fixes - Command buffer suballocator rockchip: - CDN DisplayPort support - IOMMU support for arm64 platform imx-drm: - Fix i.MX5 TV encoder probing - Remove lower fb size limits msm: - Support for HW cursor on MDP5 devices - DSI encoder cleanup - GPU DT bindings cleanup sti: - stih410 cleanups - Create fbdev at binding - HQVDP fixes - Remove stih416 chip functionality - DVI/HDMI mode selection fixes - FPS statistic reporting omapdrm: - IRQ code cleanup dwi-hdmi bridge: - Cleanups and fixes adv-bridge: - Updates for nexus sii8520 bridge: - Add interlace mode support - Rework HDMI and lots of fixes qxl: - probing/teardown cleanups ZTE drm: - HDMI audio via SPDIF interface - Video Layer overlay plane support - Add TV encoder output device atmel-hlcdc: - Rework fbdev creation logic tegra: - OF node fix fsl-dcu: - Minor fixes mali-dp: - Assorted fixes sunxi: - Minor fix" [ This was the "fixed" pull, that still had build warnings due to people not even having build tested the result.

Documentation/gpu: drm-mm.rst: fix formatting for struct vm_operations_struct

2017-01-31T20:15:49Z

drm-mm.rst contains some unformatted dump of the vm_operations_struct structure. Add some C formatting around it and some context for the dump. While there, update the structure to resemble the new signature for the fault handler after commit 25d3db7600b8 (mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf).

Documentation/gpu: Move LPE audio section after HD-audio

2017-01-26T10:25:01Z

As Daniel suggested, it makes more sense and reduces the conflicts. Also, while we're at it, tidy up the section title from all lower letters. Signed-off-by: Takashi Iwai

drm: Update kerneldoc for drm_crtc.[hc]

2017-01-25T15:36:23Z

After going through all the trouble of splitting out parts from drm_crtc.[hc] and then properly documenting each I've entirely forgotten to show the same TLC for CRTCs themselves! Let's make amends asap. v2: Review from Eric. Reviewed-by: Eric Engestrom Signed-off-by: Daniel Vetter

drm/i915: setup bridge for HDMI LPE audio driver

2017-01-25T13:21:47Z

Enable support for HDMI LPE audio mode on Baytrail and Cherrytrail when HDaudio controller is not detected Setup minimum required resources during i915_driver_load: 1. Create a platform device to share MMIO/IRQ resources 2. Make the platform device child of i915 device for runtime PM. 3. Create IRQ chip to forward HDMI LPE audio irqs. HDMI LPE audio driver (a standalone sound driver) probes the LPE audio device and creates a new sound card.

drm: Document drm_cache interface

2017-01-10T10:16:33Z

Notice that this uncovers an issue with the kernel-doc handling of array arguments, causing the first parameter of drm_clflush_pages() to not show up in the rst-generated page. A proposed fix is under review in linux-doc: Changes since v1: - Add section to drm-mm.rst. - Fix kernel-doc style issues. - s/memory/kernel memory/.
