[PATCH v2 0/4] 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.

Thanks,
Stefan

Changes in v2:
- Add missing (uintptr_t) cast to remove compile time warning

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
