This is an RFC serie of patches containing rework of OpenFirmware GPIO binding.
It permits very simple binding of most i2c/spi/etc. GPIO expanders (e.g.
to use pcf8574x driver I had only to patch in support for working w/o platform
data, no OF-specific code at all).
Dmitry Eremin-Solenikov (5):

mcu_mpc8349emitx: port to new of gpio interface
mpc8xxx_gpio: port to new of gpio interface
simple_gpio: port to new of gpio interface
qe_gpio: port to new of gpio interface
