[0/6] Use MFD framework for SGI IOC3 drivers

Message

Thomas Bogendoerfer April 8, 2019, 2:20 p.m. UTC

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.

Thomas Bogendoerfer (6):
  MIPS: SGI-IP27: remove ioc3 ethernet init
  MIPS: SGI-IP27: remove setup of RTC platform device
  mfd: ioc3: Add driver for SGI IOC3 chip
  MIPS: SGI-IP27: fix readb/writeb addressing
  tty: serial: Add 8250-core base IOC3 driver
  Input: add IOC3 serio driver
