Subject[PATCH v4] usb: phy: samsung: Add support to set pmu isolation
Date
Changes form v3:
- Removing the hostphy_en_mas since this gets used in forthcoming patches
only when host phy support is added.
- Resolving few nits:
- using 'const' specifier for driver data structures.
- using ARRAY_SIZE() instead of giving magic number
for of_property_read_u32_array()

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
phandle.
- 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.
