patch "phy: sun4i-usb: Support set_mode to USB_HOST for non-OTG PHYs" added to usb-linus

This is a note to let you know that I've just added the patch titled

phy: sun4i-usb: Support set_mode to USB_HOST for non-OTG PHYs

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: phy: sun4i-usb: Support set_mode to USB_HOST for non-OTG PHYs

While only the first PHY supports mode switching, the remaining PHYs work in USB host mode. They should support set_mode with mode=USB_HOST instead of failing. This is especially needed now that the USB core does set_mode for all USB ports, which was added in commit b97a31348379 ("usb:
core: comply to PHY framework").

Make set_mode with mode=USB_HOST a no-op instead of failing for the non-OTG USB PHYs.
