drm/i915/dp: there is no audio on port A

2015-06-09T17:43:34+00:00

[ Upstream commit 9fcb1704d1d51b12e2f03c78bca013d0cbbb7c98 ] The eDP port A register on PCH split platforms has a slightly different register layout from the other ports, with bit 6 being either alternate scrambler reset or reserved, depending on the generation. Our misinterpretation of the bit as audio has lead to warning. Fix this by not enabling audio on port A, since none of our platforms support audio on port A anyway. v2: DDI doesn't have audio on port A either (Sivakumar Thulasimani) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89958 Reported-and-tested-by: Chris Bainbridge Cc: stable@vger.kernel.org Reviewed-by: Sivakumar Thulasimani Signed-off-by: Jani Nikula Signed-off-by: Sasha Levin
