Hi,
The way pins, groups and functions are tied is too constraining for some
controllers. It concerns mainly the ones we don't care about groups and
functions, each pin can be muxed to any functions.
The goal of these two patches is too remove some of the constraints.
I have added the prototype
When having a controller which allows per pin muxing, declaring with
which groups a function can be used is a useless constraint since groups
are something virtual.

Draft for a future controller which can mux each pin to any functions.
There are up to 6 functions plus a gpio mode (gpio controller driver
won't be included in the pincontroller driver).
There is a concept of ioset. An ioset is a set of pins for a device.
A device can have several iosets.

Using a string to describe a pin in the device tree can be not enough.
Some controllers may need extra information to fully describe a pin. It
concerns mainly controllers which have a per pin muxing approach which
don't fit well the notions of groups and functions.
Instead of using a pin name, a
