[Intel-gfx] [PATCH 06/56] drm/i915/display: Simplify GLK display version tests

Matt Roper matthew.d.roper at intel.com
Thu Mar 11 22:35:42 UTC 2021 

GLK has always been a bit of a special case since it reports INTEL_GEN()
as 9, but has version 10 display IP.  Now we can properly represent the
display version as 10 and simplify the display generation tests
throughout the display code.

Aside from manually adding the version to the glk_info structure, the
rest of this patch is generated with a Coccinelle semantic patch:

        @@ expression dev_priv; @@
        - DISPLAY_VER(dev_priv) >= 10 || IS_GEMINILAKE(dev_priv)
