Subject: [PATCH 0/6] video: s3c-fb: Use runtime suspend while blanked
Date: Tue, 27 Dec 2011 14:15:51 +0000	[thread overview]
Message-ID: <20111227141550.GA3331@opensource.wolfsonmicro.com> (raw)

This patch series (the first two of which I posted the other day)
improves the runtime power management in the s3c-fb driver by moving it
to keeping the device runtime suspended when the screen is powered down
by userspace.  This saves a trivial amount of power in the framebuffer
controller and allows the SoC core code to enter system wide idle
states which offer much more substantial gains.

Currently it's only lightly tested but it certainly seems to the right
thing for me.
