[PATCH 08/11] powerpc/mpc5121: add USB host support
Anatolij Gustschin

Wed Jan 20 07:24:10 EST 2010
Platform specific code for MPC5121 USB Host support.
MPC5121 Rev 2.0 silicon EHCI registers are big endian.
Add appropriate support by specifying "big-endian-regs"
property in device tree node for USB controller. Also
allow specifying DRVVBUS and PWR_FAULT signal polarity
of MPC5121 internal PHY using "invert-drvvbus" and
"invert-pwr-fault" properties.
