It is meaningless the glue layer driver has its own platform flag
which is the same meaning with common platform flag.

All imx usb controller's non core registers uses the same clock gate with
core registers, the usbmisc_imx is the library for imx glue driver, the
glue keeps clock on when it calls usbmisc_imx API to change non-core register.
Besides, we will support runtime pm in the future, it also needs to

It moved platform_set_drvdata(pdev, ci) before hcd is created,
and the hcd will assign itself as ci controller's drvdata during
the hcd creation function (in usb_create_shared_hcd), so it
overwrites the real ci's drvdata which we want to
Hi Greg,
I find one bug that existed at chipidea driver in patch series
which I sent you for v3.19, it will cause oops during the system
suspend routine at host mode, hope it is not too late for merge.
Apologize for that.

As usb function drivers assumes that all usb request will be completed
before function unbind call, we should supply such behavior. In some
cases ep_disable() won't kill all request effectively, because some
IN requests can be in running state. In such situation it's possible
to have unbind functio

This patch to add a generic PHY driver for ROCKCHIP usb PHYs,
currently this driver can support RK3288. The RK3288 SoC have
three independent USB PHY IPs which are all configured through a
set of registers located in the GRF (general register files)
module.
