drm/i915: Introduce i915_has_asle() (f3e30485) · Commits · 戴 / test

We want to allow the desktop PNV to not have .is_mobile set. To that end let's add a small helper to determine if the platform has the ASLE interrupt (or equivalent). Supposdely both PNV variants have it. Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by:
