Merge tag 'drm-fixes-2019-04-12' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "Fixes across the driver spectrum this week, the mediatek fbdev support might be a bit late for this round, but I looked over it and it's not very large and seems like a useful feature for them. Otherwise the main thing is a regression fix for i915 5.0 bug that caused black screens on a bunch of Dell XPS 15s I think, I know at least Fedora is waiting for this to land, and the udl fix is also for a regression since 5.0 where unplugging the device would end badly. core: - make atomic hooks optional i915: - Revert a 5.0 regression where some eDP panels stopped working - DSI related fixes for platforms up to IceLake - GVT (regression fix, warning fix, use-after free fix) amdgpu: - Cursor fixes - missing PCI ID fix for KFD - XGMI fix - shadow buffer handling after reset fix udl: - fix unplugging device crashes. mediatek: - stabilise MT2701 HDMI support - fbdev support tegra: - fix for build regression in rc1. sun4i: - Allwinner A6 max freq improvements - null ptr deref fix dw-hdmi: - SCDC configuration improvements omap: - CEC clock management policy fix" * tag 'drm-fixes-2019-04-12' of git://anongit.freedesktop.org/drm/drm: (32 commits) gpu: host1x: Fix compile error when IOMMU API is not available drm/i915/gvt: Roundup fb->height into tile's height at calucation fb->size drm/i915/dp: revert back to max link rate and lane count on eDP drm/i915/icl: Fix port disable sequence for mipi-dsi drm/i915/icl: Ungate ddi clocks before IO enable drm/mediatek: no change parent rate in round_rate() for MT2701 hdmi phy drm/mediatek: using new factor for tvdpll for MT2701 hdmi phy drm/mediatek: remove flag CLK_SET_RATE_PARENT for MT2701 hdmi phy drm/mediatek: make implementation of recalc_rate() for MT2701 hdmi phy drm/mediatek: fix the rate and divder of hdmi phy for MT2701 drm/mediatek: fix possible object reference leak drm/i915: Get power refs in encoder->get_power_domains() drm/i915: Fix pipe_bpp readout for BXT/GLK DSI drm/amd/display: Fix negative cursor pos programming (v2) drm/sun4i: tcon top: Fix NULL/invalid pointer dereference in sun8i_tcon_top_un/bind drm/udl: add a release method and delay modeset teardown drm/i915/gvt: Prevent use-after-free in ppgtt_free_all_spt() drm/i915/gvt: Annotate iomem usage drm/sun4i: DW HDMI: Lower max. supported rate for H6 Revert "Documentation/gpu/meson: Remove link to meson_canvas.c" ...
