From: Sean Paul Date: Thu, 3 Apr 2014 15:10:58 +0000 (+0530) Subject: drm/exynos: Don't reset hdmiphy on hdmi off X-Git-Tag: firefly_0821_release~176^2~3773^2~17^2~44 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=35b95ac5c3fbf93c8d42187d5688db3e89a12f61;p=firefly-linux-kernel-4.4.55.git drm/exynos: Don't reset hdmiphy on hdmi off This patch removes the hdmiphy reset in hdmi_poweroff. The hdmiphy reset was added to take advantage of exynos clockgating, doing it would gate the entire TV domain. Unfortunately, mixer is included in the TV domain and its vsync interrupts are stopped when TV is gated.
