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. v4: - usb-uhci.yaml - fix errors 'make dt_binding_check' - uhci-platform.c - remove IS_ERR_OR_NULL(uhci->rsts) check, due to reset_control_assert will return 0, when uhci->rsts is null. - use dma_mask_32 as default, and just add aspeed,ast2700-uhci for dma_64. v3: - uhci-platform.c - add reset_control_assert in uhci_hcd_platform_remove. v2: - usb-uhci.yaml - add required resets for aspeed,ast2700-uhci - uhci-platform.c - change the err_clk before err_reset.
