Yes, I think the USB PHY handling for all exynos chips should be changed from an ad-hoc method to a more formal device driver. As I commented in another patch of this series, I think the main problem is that treat the USB PHY as a property of the "platform", which it really isn't. We have a bunch of other USB PHY drivers for other platforms that are inside of the drivers/usb hierarchy. For all I know, there is no formal USB PHY driver API yet, and it seems that it would be a good idea to introduce one now, but for now, just move the code to drivers/usb/phy/ and make it one file per different kind of PHY.
