This patch series for Realtek USB2 PHY driver adds support for RTL9607C
USB2 PHY.
RTL9607C is a big endian MIPS CPU which is quite far from RTD series SoCs
supported by realtek usb2 phy driver, but the phy initilization is found
to be very indentical in most areas.
Most of the code was based on the Realtek's usb driver from the GPL tarball
in [1] and adjusted to fit into the realtek usb2 phy driver code format.
The patch series was split into smaller patches that add/change something
in the driver that are not exactly related to RTL9607C and that also
helps for easier review. That also means, patch 5 depends on all the prior
patches that come before it.
USB2 PHY on RTL9607C is primarly used for its internal OHCI/EHCI controllers.
