[igt-dev] [PATCH i-g-t 0/7] Add tests for HDR metadata interfaces and bpc switch

[Swati Sharma]

This series contains tests to validate HDR metadata interfaces
and bpc switch test cases (8bpc<->10bpc).
Minor changes are made in the original patch series 
https://patchwork.freedesktop.org/patch/255755/

Changes made to the original series:
*Current version is made compatible for both amd and intel driver,
earlier it could be used by amd driver only.
*No assumption is made regarding output. Tests will execute on
all availabe outputs, since there is no ROI to execute
tests on all the pipes; tests will execute on single pipe.
*To make tests generic, moved tests from tests/amdgpu/amd_hdr.c to
tests/kms_hdr.c.
*Also, splitted the hdr igt into multiple patches so that subtests
can be easily reviewed.
*Renaming of functions, addition of new flags, igt_describe()

As per current design, test will execute on all the attached
monitors even if its non-HDR because we haven't exposed any property
from kernel to tell userspace whether monitor is hdr or not.
TODO: Either expose debugfs entry (or) parse edid in IGT to know
      whether monitor supports hdr

Also, amd exposes max_bpc as a debugfs entry..so it's asserted for their
driver. i915 drives misses that.
TODO: Expose max_bpc as debugfs entry in i915 driver too, if required.
