This patch series adds support for the UHCI controller found on the
Aspeed AST2700 SoC.

Compared to earlier SoCs (AST2400/2500/2600), AST2700 UHCI:
- requires a reset line to be deasserted before use
- supports 64-bit DMA addressing

This series updates the bindings and platform driver accordingly.

v2:
- usb-uhci.yaml
- add required resets for aspeed,ast2700-uhci
- uhci-platform.c
- change the err_clk before err_reset.
