[PATCH 0/4] pin controller subsystem v6

From: Linus Walleij

From: Linus Walleij <linus.walleij@xxxxxxxxxx>

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

ChangeLog v5->v6:

- Create an abstract pin group concept that can sort pins into
named and enumerated groups no matter what the use of these
groups may be, one possible usecase is a group of pins being
muxed in or so. The intention is however to also use these
groups for other pin control activities.

- Make it compulsory for pinmux functions to associate with
at least one group, so the abstract pin group concept is used
to define the groups of pins affected by a pinmux function.
The pinmux driver interface has been altered so as to enforce
a function to list applicable groups per function.

- Provide an optional .group entry in the pinmux machine map
so the map can select beteween different available groups
to be used with a certain function.

- Consequent changes all over the place so that e.g. debugfs
present reasonable information about the world.

- Drop the per-pin mux (*config) function in the pinmux_ops
struct - I was afraid that this would start to be used for
things totally unrelated to muxing, we can introduce that to
the generic struct pinctrl_ops if needed. I want to keep
muxing orthogonal to other pin control subjects and not mix
these things up.

Linus Walleij (4):
drivers: create a pin control subsystem v6
pinmux: add a driver for the U300 pinmux
amba: request muxing for PrimeCell devices
mach-u300: activate pinmux driver, delete old padmux driver
