From: Daniel Vetter Date: Wed, 16 Oct 2013 20:55:58 +0000 (+0200) Subject: drm/i915: Add new CRC sources X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3d099a05b121727bfa797391ea1da15eb33eac16;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Add new CRC sources On pre-gen5 and vlv we can't use the pipe source when TV-out or a DP port is connected to the pipe. Hence we need to expose new CRC sources. Also simplify the existing pipe source platform code a bit by rejecting all unhandled sources by default.
