Subject: [PATCH v3 0/7] Use MFD framework for SGI IOC3 drivers

SGI IOC3 ASIC includes support for ethernet, PS2 keyboard/mouse,
NIC (number in a can), GPIO and a byte  bus. By attaching a
SuperIO chip to it, it also supports serial lines and a parallel
port. The chip is used on a variety of SGI systems with different
configurations. This patchset moves code out of the network driver,
which doesn't belong there, into its new place a MFD driver and
specific platform drivers for the different subfunctions.

Changes in v3:
 - use 1-wire subsystem for handling proms
 - pci-xtalk driver uses prom information to create PCI subsystem
   ids for use in MFD driver
 - changed MFD driver to only use static declared mfd_cells
 - added IP30 system board setup to MFD driver
 - mac address is now read from ioc3-eth driver with nvmem framework 

Changes in v2:
 - fixed issue in ioc3kbd.c reported by Dmitry Torokhov
 - merged IP27 RTC removal and 8250 serial driver addition into
   main MFD patch to keep patches bisectable

Thomas Bogendoerfer (7):
  nvmem: core: add nvmem_device_find
  MIPS: PCI: refactor ioc3 special handling
  MIPS: PCI: use information from 1-wire PROM for IOC3 detection
  MIPS: SGI-IP27: remove ioc3 ethernet init
  mfd: ioc3: Add driver for SGI IOC3 chip
  MIPS: SGI-IP27: fix readb/writeb addressing
  Input: add IOC3 serio driver
