[Intel-gfx] [PATCH 6/6] drm/i915/cnp: Panel Power sequence changes for CNP PCH.
Panel Power sequences for CNP is similar to Broxton,
but with only one sequencer.
Main difference from SPT is that PP_DIVISOR was removed
and power cycle delay has been moved to PP_CONTROL.
v2: Add missed pp_div write, that is now part of PP_CONTROL[8:4]
as on Broxton. (Found by DK)
v3: Improve commit message. (By DK)

Re: [Intel-gfx] [PATCH 6/6] drm/i915/cnp: Panel Power sequence changes for CNP PCH.
Jani, Daniel, could I merge the 5 patches already after CI respond?
I rebased and retest here on CNL But I'd like to start merging so
we unblock CFL as well, maybe on top of this CNP before CNL...
Jani, also I believe you would be the best reviewer for this 6th patch
here, could you please consider taking a look?
Thanks,
Rodrigo.
