s3c-hsudc powerdomain using generic power domains

A patchset in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Sun, 8 Jan 2012 21:38:30 +0100

The S3C2443/S3C2416/S3C2450 contain a power domain for the usb phy. Up until now the s3c-hsudc was writing directly to the PWRCFG register in the (un)init_phy functions to control it. This patchset introduces a power domain for the usbphy and hooks the hsudc-device to it. The new runtime_pm calls then handle the enabling and disabling of the power domain on udc start and stop. As a result another arch dependency is gone from the driver. This set applies cleanly to linux-next from 2012-01-06 and is tested on S3C2416 hardware.
