Subject: [RFC][PATCH 0/4] PM / shmobile: Use PM QoS latency constraints in touchscreen driver

Hi,

The following series of patches updates the SH7372 PM domain's so that
A4R doesn't need to be turned on during system sleep, drops the SH7372's
PM domains stay_on flag and makes the touchscreen add a PM QoS constraint
on its I2C controller to prevent the A4R domain containing it from being
turned off (due to power management) when the touchscreen is active.

Comments welcome!

Thanks,
Rafael
