[PATCH v2 1/6] drm/i915: Enable display workaround 827 for all planes, v2.

[Vidya Srinivas]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

The workaround was applied only to the primary plane, but is required
on all planes. Iterate over all planes in the crtc atomic check to see
if the workaround is enabled, and only perform the actual toggling in
the pre/post plane update functions.

Changes since v1:
- Track active NV12 planes in a nv12_planes bitmask. (Ville)

[PATCH v2 4/6] drm/i915: Add NV12 support to intel_framebuffer_init

[Vidya Srinivas]

From: Chandra Konduru <chandra.konduru@intel.com>

This patch adds NV12 as supported format
to intel_framebuffer_init and performs various checks.

v2:
-Fix an issue in checks added (Chandra Konduru)

v3: rebased (me)

v4: Review comments by Ville addressed
Added platform check for NV12 in intel_framebuffer_init
Removed offset checks for NV12 case

v5: Addressed review comments by Clinton A Taylor
This NV12 support only correctly works on SKL.
Plane color space conversion is different on GLK and later platforms
causing the colors to display incorrectly.
Ville's plane color space property patch series
in review will fix this issue.
- Restricted the NV12 case in intel_framebuffer_init to
SKL and BXT only.

v6: Rebased (me)

v7: Addressed review comments by Ville
Restricting the NV12 to BXT for now.

v8: Rebased (me)
Restricting the NV12 changes to BXT and KBL for now.

v9: Rebased (me)

v10: NV12 supported by all GEN >= 9.
Making this change in intel_framebuffer_init. This is
part of addressing Maarten's review comments.
Comment under v8 no longer applicable

v11: Addressed review comments from Shashank Sharma

v12: Adding Reviewed By from Shashank Sharma

v13: Addressed review comments from Juha-Pekka Heikkila
"NV12 not to be supported by SKL"

v14: Addressed review comments from Maarten.
Add checks for fb width height for NV12 and fail the fb
creation if check fails. Added reviewed by from
Juha-Pekka Heikkila

v15: Rebased the series

v16: Setting the minimum value during fb creating to 16
as per Bspec for NV12. Earlier minimum was expected
to be > 16. Now changed it to >=16.

v17: Adding restriction to framebuffer_init - the fb
width and height should be a multiplier of 4

[PATCH v2 5/6] drm/i915: Enable Display WA 0528

[Vidya Srinivas]

Possible hang with NV12 plane surface formats.
WA: When the plane source pixel format is NV12,
the CHICKEN_PIPESL_* register bit 22 must be set to 1
and the render decompression must not be enabled
on any of the planes in that pipe.

v2: removed unnecessary POSTING_READ

[PATCH v2 6/6] drm/i915: Do not do fb src adjustments for NV12

[Vidya Srinivas]

We skip src trunction/adjustments for
NV12 case and handle the sizes directly.
Without this, pipe fifo underruns are seen on APL/KBL.

v2: For NV12, making the src coordinates multiplier of 4
