From: Rafael J. Wysocki Date: Fri, 23 Dec 2011 00:24:25 +0000 (+0100) Subject: PM / input / touchscreen: Make st1232 use device PM QoS constraints X-Git-Tag: v3.3-rc1~167^2~2^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ee27ffbe303ce18e7336115f1d443e9911eba53;p=pandora-kernel.git PM / input / touchscreen: Make st1232 use device PM QoS constraints Make the st1232 driver use dev_pm_qos_add_ancestor_request() to add a device PM QoS latency constraint for the controller it depends on, so that the controller won't go into an overly deep low-power state when the touchscreen has to be particularly responsive (e.g. when the user moves his or her finger on it). This change is based on a prototype patch from Guennadi Liakhovetski. Signed-off-by: Rafael J. Wysocki --- Reading git-diff-tree failed
