Pull drm updates from Dave Airlie: "Not a major amount of change, the i915 trees got split into display and gt trees to better facilitate higher level review, and there's a major refactoring of i915 GEM locking to use more core kernel concepts (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards get DC support, nouveau got a bump in displayport support with common code extraction from i915.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+1
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2018-09-27Revert "drm/sun4i: Remove R40 display pipeline compatibles"Chen-Yu Tsai1-0/+24
This reverts commit 3510e7a7f91088159bfc67e8abdc9f9e77d28870. During the 4.19 merge window for drm-misc, two patches critical to supporting the display pipeline on the Allwinner R40 SoC were missed. They were applied later but missed the merge window deadline. As a result 4.19-rc1 kernel would crash on the R40 when it couldn't parse the new device tree structure. We ended up removing support for the R40 display pipeline for 4.19. Since the missing patches are already merged for 4.20, we can now revert the commit that removed support.

2018-09-10drm/sun4i: Remove R40 display pipeline compatiblesChen-Yu Tsai1-24/+0
Two patches from the R40 display pipeline support series weren't applied with the rest of the series. When they did get applied, the -rc6 deadline for drm-misc-next had past, so they didn't get into 4.19-rc1 with the rest of the series. However, the two patches are crucial in the parsing of the R40's display pipeline graph in the device tree. Without them, the driver crashes because it can't follow the odd graph structure. This patch removes the R40 compatibles from the sun4i-drm driver, effectively disabling DRM support for the R40 for one release cycle. This will prevent the driver from crashing upon probing. The compatibles should be reinstated for the next release.

2018-07-17drm/sun4i: sun8i: Avoid clearing blending order at each atomic commitPaul Kocialkowski1-12/+3
Blending order is set based on the z position of each DRM plane. The blending order register is currently cleared at each atomic DRM commit, with the intent that each committed plane will set the appropriate bits (based on its z-pos) when enabling the plane. However, it sometimes happens that a particular plane is left unchanged by an atomic commit and thus will not be configured again. In that scenario, blending order is cleared and only the bits relevant for the planes affected by the commit are set. This leaves the planes that did not change without their blending order set in the register, leading to that plane not being displayed. Instead of clearing the blending order register at every atomic commit, this change moves the register's initial clear at bind time and only clears the bits for a specific plane when disabling it or changing its zpos. This way, planes that are left untouched by a DRM atomic commit are no longer disabled.

2018-07-12drm/sun4i: Implement zpos for DE2Jernej Skrabec1-3/+12
Initial implementation of DE2 planes only supported fixed zpos. Expand implementation with configurable zpos property. Implementation background: Channel in DE2 driver represents one DRM plane, whereas pipe is just mapped channel to known Z position. Pipe 0 will always be at the bottom, pipe 1 just above pipe 0 and so on. If, for example, channel 1 is mapped at pipe 0 and channel 0 at pipe 1, whatever is on channel 0 will appear on top. Before this commit, channel id was used for addressing channel related registers (prefixed with SUN8I_MIXER_CHAN_UI_ or SUN8I_MIXER_CHAN_VI_) and pipe registers (prefixed with SUN8I_MIXER_BLEND_). Additionally, register SUN8I_MIXER_BLEND_ROUTE, which takes care for mapping channels to pipes had fixed value. It mapped channel 0 to pipe 0, 1 to 1 and so on. Consequence of all that was fixed Z order of planes. With this commit, pipe registers are using zpos property as index and channel related registers still use channel id as index. Pipe mapping register is now set dynamically too and pipe enable register is rebuild every time to make sure only active pipes are enabled. Testing was done to confirm that there is no issues if bottom plane contains pixels with alpha value < 0xff and if it doesn't whole screen.

Currently, TCON supports 2 ways to match TCON with engine (mixer in this case). Old way is to just traverse of graph backwards and compare node pointer. New way is to match TCON and engine by their respective ids. All SoCs with DE2 enabled till now used the old way, which means mixer id was never used and thus never implemented. However, for R40, only the new way will be used. To prepare for that, implement mixer id fetching from DT.

2018-01-04drm/sun4i: Force the mixer rate at 150MHzMaxime Ripard1-0/+10
It seems like the mixer can only run properly when clocked at 150MHz. In order to have something more robust than simply a fire-and-forget assigned-clocks-rate, let's put that in the code.

2017-12-05drm/sun4i: Add support for DE2 VI planesJernej Skrabec1-2/+17
This commit adds basic support for VI planes. They are meant for video overlay and because of that they support YUV formats too.

2017-12-05drm/sun4i: Reorganize UI layer code in DE2Jernej Skrabec1-152/+22
Till now, DE2 driver supported only UI planes. Before we add support for VI planes, lets split out UI layer specific code from common parts. This commit does the following: - renames sun8i_layer.c to sun8i_ui_layer.c - moves UI channel specific code to sun8i_ui_layer.c - moves common code from sun8i_layer.c to sun8i_mixer.c - renames function and structure names so it is apparent where they belong to No functional change is made.

2017-12-05drm/sun4i: Move interlace related code in DE2Jernej Skrabec1-13/+20
There is no point having code which sets interlace mode of mixer in channel related function. Interlace mode will only change when CRTC state will change, so let's move it to the block which is executed only when primary plane state is changed.

Now that we have properly clipped coordinates in plane state structure, use them. This also fixes bug where source x and y were adjusted for negative value, but width and height weren't.

2017-12-05drm/sun4i: Start using layer id in DE2 driverJernej Skrabec1-29/+21
Till now, plane selection was hardcoded to first overlay in first UI channel and layer parameter is unused. Rename and add parameters to layer functions so they would represent HW more accurately and start using then. It turns out that overlays don't fit well in current DRM design, because they can't be blended together or scaled independetly when they are set to same channel. Because of that, always use only first overlay in each channel.

2017-12-05drm/sun4i: Rework enabling plane in DE2 driverJernej Skrabec1-11/+17
If we want to support multiple planes in the future, code which enables pipe has to be moved to appropriate place and it must depend on channel id instead of being hardcoded. Side effect of that rework is definition of default Z position. For now, put first channel at the bottom, second above it and so on.
