Subject: [PATCH 4.14 18/38] drm/i915: Disable DC states around GMBUS on GLK
Date: Mon, 8 Jan 2018 13:59:11 +0100 [thread overview]
Message-ID: <20180108125917.107405239@linuxfoundation.org> (raw)
In-Reply-To: <20180108125915.951963528@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
commit 3488d0237f6364614f0c59d6d784bb79b11eeb92 upstream.
Prevent the DMC from destroying GMBUS transfers on GLK. GMBUS
lives in PG1 so DC off is all we need.
