Allwinner R40 SoC has an AHCI SATA controller like the one in A10/A20,
but with a reset control and two dedicated VDD pins for this controller
(one 1.2v and one 2.5v).
Add support for it.

The Allwinner R40 SoC contains a SATA AHCI controller like the one in
A10/A20 SoCs, however a reset control and two power supplies are added
to it.
Add a binding document for it.
As a dedicated binding document is needed now for the A10/A20/R40 AHCI
controller, drop the A10 compatible line from g
Banana Pi M2 Berry has an on-board USB Hub that provides 4 USB Type-A
ports, and it's connected to the USB1 port of the SoC.
Enable it.

On the Banana Pi M2 Berry board, the 5V power output (used by HDMI, SATA
and USB) is controlled via a GPIO.
Add regulator node for it.

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.

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.
Allwinner R40 features a USB PHY like the one in A64, but with 3 PHYs.
Add support for it.

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 R40 support to the USB PHY driver.
The second patch adds USB PHY and EHCI/OHCI nodes to the R40 DTSI.
The thrid and fourth patch adds 5V regulator for t
