The work is based on ci13xxx rework done by Alexander Shishkin.
To let Greg pick up, I also added patches Alex queued that I depends on.
This patch series can also be found at:
https://github.com/riczhao/kernel-imx/commits/topics/usb-driver
Status:
- this version only support host
- usbotg
Platform drivers do the similar things to add/remove ci13xxx device, so
create a unified one.
