[PATCH v2 0/5] Allwinner R40 USB host support (DT part)

[Icenowy Zheng]

This patchset adds support for the USB host ports on Allwiner R40, and
enable them on Banana Pi M2 Ultra and Berry boards.

The first patch adds USB PHY and EHCI/OHCI nodes to the R40 DTSI.

The second and third patch adds 5V regulator for the two boards, and
the fourth and fifth patch finally adds USB host ports support.

[PATCH v2 1/5] ARM: sun8i: r40: add USB host port nodes for R40

[Icenowy Zheng]

From: Icenowy Zheng <icenowy-ymACFijhrKM@public.gmane.org>

Allwinner R40 SoC features a USB OTG port and two USB HOST ports.

Add support for the host ports in the DTSI file.

The OTG controller still cannot work with existing compatibles, and needs
more investigation. So it's not added yet.

Changes in v2:
- Dropped the bogus OHCI resources in EHCI device node.

[PATCH v2 2/5] ARM: sun8i: r40: add 5V regulator for Banana Pi M2 Ultra

[Icenowy Zheng]

On newer revisions of the Banana Pi M2 Ultra boards, the 5V power output
(used by HDMI, SATA and USB) is controller via a GPIO.

Add the regulator node for it.

Older revisions just have the 5V power output always on, and the GPIO is
reserved on these boards. So it won't affect the older revisions.

What is the USB hub chip's model? If it's a USB 2.0 hub, then you
don't need to enable the OHCI.
