Subject: [PATCH 0/8] Third pinconfig patches, with example

From: Linus Walleij <linus.walleij@...aro.org>

This is a third iteration of the pinconfig patchset, including a
practical example of how I convert the U300 COH 901XXX GPIO driver
to use it alongside the existing pinmux-u300 driver. In this case
the pinmux driver can move things around but only the GPIO driver
can alter bias and drive mode, so they are working closely on the
same hardware and are thusly set to live in the same subsystem.

Linus Walleij (8):
  pinctrl: add a generic pin config interface
  ARM: u300: localize GPIO assignments
  pinctrl: move the U300 GPIO driver to pinctrl
  pinctrl: u300-pinmux: register proper GPIO ranges
  pinctrl: COH901XXX: driver to request its pins
  pinctrl: COH901XXX: probe the driver from pinmux
  pinctrl: COH901XXX: use pinconf enums and parameters
  pinctrl: support pinconfig on the U300
