Add a driver for the USB PHY on the Conexant CX92755 SoC, from the
Digicolor series of SoCs. The PHY is connected to the on-chip chipidea
usb2 host.

The hardware is somewhat similar to the phy-mxs-usb.c usb_phy, but it is
different enough to merit its own driver. Also, this driver uses the
generic phy infrastructure.

the register set looks very similar to MXS one indeed. How is it different 
please ?

Almost of the bits that are defined in the MXS USBPHY_CTRL register are not 
defined in the Digicolor one. Some have different meaning, and some are 
reserved. OTOH, the Digicolor USBPHY_CTRL register uses all bits in the 1-13 
range. Also, the Digicolor phy does not have anatop registers.

The driver looks OK.

Thanks.

BTW, do you know why the phy-mxs-usb driver calls its init from 
postcore_initcall? Is there a special need to register the driver so early?
