Series [v1,1/4] usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu) | expand

usb: xhci: Prepare xHCI driver for MIPS Octeon big-endian support

These patches fix a few issues, found while porting the xHCI to the MIPS
Octeon platforms. The basic issues here are:

- Endianess issues: missing cpu_to_leXX() & leXX_to_cpu() conversions
- Use physical (DMA) address for the xHCI DMA controller

These patches are the groundwork for the upcoming xHCI Octeon support
that will follow soon.


Stefan Roese (4):
  usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu)
  usb: xhci: xhci_mem_init: Use cpu_to_le64() and not xhci_writeq()
  usb: usb-uclass.c: Drop le16_to_cpu() as values are already swapped
  usb: xhci: Add virt_to_phys() to support mapped platforms
