[U-Boot] [PATCH v1 0/2] sunxi: MUSB support for the sun50i (A64)

[Philipp Tomsich]

The A64 has 3 USB controllers and 2 USB PHYs, but a somewhat odd
(actually it's wasteful, as there's no way to use the 2 PHYs and
the HSIC output concurrently) muxing scheme between those:
 * PHY 0 is multiplexed to either MUSB (dual-role) or HCI0
 * PHY 1 is dedicated to HCI1

This changeset fixes the common use-case of MUSB controlling PHY0
and HCI1 controlling PHY1. To have HCI0 control PHY0, additional
work will be needed to reconcile the fact that the [eo]hci_sunxi
infrastructure assumes that EHCI/OHCI controllers start at USB1.

Tested on the A64-uQ7 with MUSB (for PHY0) and HCI1 for PHY1.



Philipp Tomsich (2):
  sunxi (sun50i): Set CONFIG_SUNXI_USB_PHYS to 2 (the A64 has 2 PHYs)
  sunxi (sun50i): improved USB support for sun50i (A64)
