[PATCH 0/4 v5] pin controller subsystem v5

[Linus Walleij]

From: Linus Walleij <linus.walleij@xxxxxxxxxx>

This is the fifth iteration of the controller subsystem, most
changes are described in the first patch, copied here for reference:

ChangeLog v4->v5:

- Defined a "position" for each function, so the pin controller now
  tracks a function in a certain position, and the pinmux maps define
  what position you want the function in. (Feedback from Stephen
  Warren and Sascha Hauer).

- Since we now need to request a combined function+position from
  the machine mapping table that connect mux settings to drivers,
  it was extended with a position field and a name field. The
  name field is now used if you e.g. need to switch between two
  mux map settings at runtime.

- Switched from a class device to using struct bus_type for this
  subsystem. Verified sysfs functionality: seems to work fine.
  (Feedback from Arnd Bergmann and Greg Kroah-Hartman)

- Define a per pincontroller list of GPIO ranges from the GPIO
  pin space that can be handled by the pin controller. These can
  be added one by one at runtime. (Feedback from Barry Song)

- Expanded documentation of regulator_[get|enable|disable|put]
  semantics.

- Fixed a number of review comments from Barry Song. (Thanks!)

Linus Walleij (4):
  drivers: create a pin control subsystem v5
  pinmux: add a driver for the U300 pinmux
  amba: request muxing for PrimeCell devices
  mach-u300: activate pinmux driver, delete old padmux driver
