[PATCH v3] usb: phy: samsung: Add support to set pmu isolation

From: Vivek Gautam
Date: Fri Dec 21 2012 - 03:09:41 EST

Changes from v2:
- Removed the phandle type of device node properties, instead using
sub-nodes now.
- Removed the property 'samsung,enable-mask' since it is SoC dependent
(SoCs like S5PV210 and S3C64XX have different bits to enable/disable
phy controller in comparison to exysno4210 onwards).
- Maintaining the phy enable mask (which is SoC dependent) for device type phy
and host type phy in the driver data.
- Re-structuring to get device properties using sub-nodes for 'usbphy-pmu'

Changes from v1:
- Changed the name of property for phy handler from'samsung,usb-phyctrl'
to 'samsung,usb-phyhandle' to make it look more generic.
- Similarly 'samsung,phyctrl-reg' is changed to 'samsung,phyhandle-reg'
- Added a check for 'samsung,usb-phyhandle' before getting node from
- Putting the node using 'of_node_put()' which had been missed.
- Adding necessary check for the pointer in 'samsung_usbphy_set_isolation()'
to avoid any NULL pointer dereferencing.
- Unmapping the register ioremapped in 'samsung_usbphy_parse_dt_param()'.

Based on usb-next branch with Praveen Paneri's patches on top of it.
