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 introduc
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 o
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

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

Hi,
We are running kernel v3.5.7 on am3517 based hardware (CM-T3517 module).
Recently we faced with the following issue: am35x MUSB module fails when
trying to reinsert it.
It fails with the message "musb-hdrc.0: failed to claim resource 1", see
the console clip below:

No, not really. At least, not that I can tell at this point; maybe
later on it will be more useful.
