Supposedly both src coordinates have to even when doing 90/270
degree rotation with RGB565. This is definitely true for the
X coordinate (we just get a black screen when it is odd). My
experiments didn't show any misbehaviour with an odd
Y coordinate, but let's trust the spec and reject that one
as well.
v2: Ignore ccs hsub/vsub

As a disabled pipe in pipe_mask is not having a valid intel crtc,
driver wrongly populates the possible_crtcs mask while initializing
the plane for a CRTC. Fixing up the plane possible_crtcs mask.
changes since RFC:
- Simplify the possible_crtcs initialization. [Ville]
v2:
- Removed the unnecessary stack garbage possible_crtcs to
drm_universal_plane_init. [Ville]
v3:
- Combine the intel_crtc assignment and declaration. [Ville]
v4:
- Fix possible_crtcs abused bits from
intel_{primary,curosr,sprite}_plane_create(). [Ville]

Detect the modifier corresponding to media compression to enable
display decompression for YUV and xRGB packed formats. A new modifier is
added so that the driver can distinguish between media and render
compressed buffers. Unlike render decompression, plane 6 and plane 7 do not
support media decompression.
v2: Fix checkpatch warnings on code style (Lucas)
From DK:
Separate modifier array for planes that cannot decompress media (Ville)
v3: Support planar formats
v4: Switch plane order
v5:
- Use format block descriptors to get CCS subsampling calculation right
everywhere.
- Extend the plane state normal view array to accommodate 4 color planes.
- Use helpers to convert between main and CCS planes.
v6: Add missing packed YUV formats to the MC format list. (Yang)
v7: Align UV planes to tile-row size.

Gen-12 display decompression operates on Y-tiled compressed main surface.
The CCS is linear and has 4 bits of metadata for each main surface cache
line pair, a size ratio of 1:256. Gen-12 display decompression is
incompatible with buffers compressed by earlier GPUs, so make use of a new
modifier to identify gen-12 compression. Another notable change is that
render decompression is supported on all planes except cursor and on all
pipes. Start by adding render decompression support for [A,X]BGR888 pixel
formats.
v2: Fix checkpatch warnings (Lucas)
v3:
Rebase, disable color clear, styling changes and modify
intel_tile_width_bytes and intel_tile_height to handle linear CCS
v4:
- Use format block descriptors and the i915 specific func to get the
subsampling for each color plane.
- Use helpers to convert between CCS and main planes.
v5:
- Fix subsampling returned by intel_fb_plane_get_subsampling() for
the CCS plane of the first plane.
v6:
- Rebased on v2 of patch 4.
v7:
- Fix plane dimensions during FB check.

Now that we split plane_state which I didn't want to do yet, we can
program the slave plane without requiring the master plane.
This is useful for programming bigjoiner slave planes as well. We
will no longer need the master's plane_state.
Changes since v1:
- set src/dst rectangles after copy_uapi_to_hw_state.
Changes since v2:
- Use the correct color_plane for pre-gen11 by using planar_linked_plane != NULL.
- Use drm_format_info_is_yuv_semiplanar in skl_plane_check() to fix gen11+.

ivb+ supports fp16 pixel formats on the sprite planes planes. Expose
that capability.
On ivb/hsw fp16 scanout is slightly busted. The output from the plane
will have 1/4 the expected value. For the sprite plane we can fix that
up with the plane gamma unit. This was fixed on bdw.
v2: Rebase on top of icl fp16
Split the ivb+ sprite birs into a separate patch
v3: Move ivb_need_sprite_gamma() check one level up so that
we don't waste time programming garbage into he gamma registers

Various pixel formats and plane scaling impose additional constraints
on the cdclk frequency. Provide a new plane->min_cdclk() hook that
will be used to compute the minimum acceptable cdclk frequency for
each plane.
Annoyingly on some platforms the numer of active planes affects
this calculation so we must also toss in more planes into the
state when the number of active planes changes.
The sequence of state computation must also be changed:
1. check_plane() (updates plane's visibility etc.)
2. figure out if more planes now require update min_cdclk
computaion
3. calculate the new min cdclk for each plane in the state
4. if the minimum of any plane now exceeds the current
logical cdclk we recompute the cdclk
4. during cdclk computation take the planes' min_cdclk into
accoutn
5. follow the normal cdclk programming to change the
cdclk frequency. This may now require a modeset (except
on bxt/glk in some cases), which either succeeds or
fails depending on whether userspace has given
us permission to perform a modeset or not.
v2: Fix plane id check in intel_crtc_add_planes_to_state()
Only print the debug message when cdclk needs bumping
Use dev_priv->cdclk... as the old state explicitly

Split the format lists for different planes on skl/icl more cleanly.
On skl+ we have just two types of planes: those can do planar and
those that can't.
On icl we have three types of planes: hdr planes, sdr planes that
can do planar, and sdr planes that can't do planar. Those latter two
are the same set of planes we must when choose from when picking the
UV vs. Y plane for planar scanout. So we shall just designate
them sdr uv planes and sdr y planes.

All sprite planes have a progammable gamma ramp. Set it up with
a linear ramp on all platforms. This actually matches the reset
value but soon we'll want to reprogram this ramp on some machines,
so let's just set it up across the board.
Note that on pre-IVB the hardware bypasses the gamma unit
unless a YCbCr pixel format is used.
