Subject: [Intel-gfx] [CI 17/28] drm/i915: remove explicit CNL handling from intel_pm.c
Date: Tue, 27 Jul 2021 00:18:34 -0700	[thread overview]
Message-ID: <20210727071845.841554-17-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20210727071845.841554-1-lucas.demarchi@intel.com>

Remove support for CNL as it's highly untested, probably broken, and
there is no real platform that requires this code. This is part of CNL
removal from i915.
