Hi,
This patch set trys to prepare for support of usb port power
off mechanism on non-ACPI devices. The port power off mechasnism
has been discussed for some time[1][2], and support for ACPI
devices has been in shape:
- usb port device is introduced
- port connect type is
Power controller is an abstract on simple power on/off switch.
One power controller can bind to more than one device, which
provides power logically, for example, we can think one usb port
in hub provides power to the usb device attached to the port, even
though the power is supplied actually by
The global device ADD/DEL notifier is introduced so that
some platform code can bind some device resource to the
device. When this platform code runs, there is no any bus
information about the device, so have to resort to the
global notifier.

This patch applies the power controller on usb port, so that
hub driver can power on one port which isn't provided power
by bus.

This patch defines power controller for powering on/off LAN95xx
USB hub and USB ethernet devices, and implements one match function
to associate the power controller with related USB port device.
The big problem of this approach is that it depends on the global
device ADD/DEL notifier.

This series migrates it to the hub driver as suggested by
Felipe Balbi.

Both OMAP4 and 5 exhibit the same revision ID in the REVISION register
but they have different number of ports i.e. 2 and 3 respectively.
So we can't rely on REVISION register for number of ports on OMAP5
