The USB port 2 on PXA310 is an OTG port which can be utilized by OHCI controller
in host mode and by high-speed USB device controller in device mode.
Enabling this port in host mode only still requires manipulation of UDC and
OTG controller registers for proper USB PHY initialization.
This patch series add a minimalistic implementation of PHY configuration mechanism
that can be used across PXA310 based platforms.
Igor Grinberg (2):
[ARM] pxa: add minimal ULPI functionality for USB host port 2 on
PXA310.
[ARM] pxa/cm-x300: enable USB host port 2 on modules with PXA310 cpu.
