This patch adds extcon notifier callback to set the mode of

This patch set is based on the Felipe's usb.git / testing/next branch
(commit id = f2830ad455ec0fdc386baeb9d654f7095bf849da).
Yoshihiro Shimoda (4):
usb: renesas_usbhs: Add a function to write the UGCTRL2 register
usb: renesas_usbhs: add a new callback for extcon notifier
usb: renesas_usbhs:
The usbhs_rcar3_power_and_pll_ctrl() will be used by non-otg channel
(e.g. R-Car D3) and the previous code has hardcoded as peripheral mode.
So, this patch sets the mode by using extcon state.
If the channel doesn't get any extcon devices, this driver's behavior
is the same as before.

A malicious USB device with crafted descriptors can cause the kernel
to access unallocated memory by setting the bNumInterfaces value too
high in a configuration descriptor. Although the value is adjusted
during parsing, this adjustment is skipped in one of the error return
paths.

On rk3288-veyron devices on Chrome OS it was found that plugging in an

if the CPU Frequency was at one of the slower operating points (like
100 MHz / 200 MHz).

When plugging in a USB webcam I see the following message:
xhci_hcd :04:00.0: WARN Successful completion on short TX: needs
XHCI_TRUST_TX_LENGTH quirk?
handle_tx_event: 913 callbacks suppressed
All is quiet again with this patch (and I've done a fair but of soak
testing with the camera since).
