Cover letter [PATCH 0/6] video: s3c-fb: Use runtime suspend while blanked
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.
