Subject: [Intel-gfx] [PATCH 17/25] drm/i915: remove explicit CNL handling from intel_pm.c
Date: Wed, 28 Jul 2021 14:59:38 -0700	[thread overview]
Message-ID: <20210728215946.1573015-18-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20210728215946.1573015-1-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.
