[RFC 0/9] ehci-hcd.c: make it works on big-endian mips (AR9331)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchseries is very preliminary and has several issues:

  * USBMODE_BE bit set does not work on AR9331
    see the 'usb: ehci: add big-endian registers support' patch
  * tested on USB-flash; I have to test E100 USB Ethernet too;
  * the 'usb: ehci-hcd: add OF bindings' patch is not taken into account;
    see http://lists.infradead.org/pipermail/barebox/2015-August/024545.html
