Subject: [Update][PATCH 0/5] PM / shmobile: Use PM QoS latency constraints in touchscreen driver on SH7372

Hi,

I have reworked the patchset slightly.

The first two patches are unchaged (apart from the Magnus' ACKs), as well
as the third one.  The fourth one, though, has been split as suggested by
Guennadi and the touchscreen part has been simplified slightly.

[1/5] - Don't include SH7372's INTCS in syscore suspend/resume.
[2/5] - Remove the stay_on flag from SH7372's PM domains.
[3/5] - Introduce dev_pm_qos_add_ancestor_request().
[4/5] - Make st1232 use device PM QoS constraints.
[5/5] - Allow the A4R domain to be turned off and on at runtime.

Thanks,
Rafael
