Subject: [PATCH 0/3] s3c-hsudc powerdomain using generic power domains
Date: Sun, 8 Jan 2012 21:56:43 +0100 [thread overview]
Message-ID: <201201082156.44142.heiko@sntech.de> (raw)
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.

s3c-hsudc: Use helper functions instead of generic container_of
s3c-hsudc: add basic runtime_pm calls
S3C2443: add power domain for usb phy
