[PATCH 0/5] usb: renesas_usbhs: use otg mode and add support for R-Car E3

[Yoshihiro Shimoda]

This patch set is based on the latest Greg's usb.git / usb-testing branch
(the commit id is ae8a2ca8a2215c7e31e6d874f7303801bb15fbbc)

The previous code set the mode as peripheral mode by the UGCTRL2 register
for R-Car D3. But, this SoC can select OTG mode in fact. So, at first,
I'd like to revert related patches I submitted in patch 1 and 2.
Then, in patch 3, it sets the mode as "OTG" and in patch 4 and 5, it
supports for R-Car E3.

To use this controller for R-Car D3 and E3, we need the following
patch set. Otherwize, the mode will not be changed to peripheral mode
by the phy's COMMCTRL register:

[PATCH 1/5] Revert "usb: renesas_usbhs: add extcon notifier to set mode for non-otg channel"

[Yoshihiro Shimoda]

This reverts commit 8ada211d0383b72878582bd312b984a9eae62b30.

R-Car D3 can use OTG mode in fact. So, the commit doesn't need anymore.
In other words, like other R-Car Gen3 SoCs, R-Car D3 can change the mode
by using the phy-rcar-gen3-usb2 driver.
