[PATCH v2 0/5] usb: atmel_usba_udc: Rework errata handling

Here is a set of patches porting existing at91sam9rl erratum handling to
DT and adding new code to handle at91sam9g45/9x5 erratum.
It also adds several compatible strings to differentiate those errata.

These patches should be backported to 3.17 and 3.18 stable releases but
they do not apply cleanly on those stable branches.
I'll send a backport of this series once it is merged in mainline.



Changes since v1:
- cache INT_ENB value to speedup INT_ENB read operations

  usb: atmel_usba_udc: Rework at91sam9rl errata handling
  usb: atmel_usba_udc: Add at91sam9g45 and at91sam9x5 errata handling
  ARM: at91/dt: update udc compatible strings
