This adds a driver for mmio-based syscon multiplexers controlled by bitfields in a syscon register range. This is heavily based on the linux mmio-mux driver.

The mux framework is a minimalistic subsystem that handles multiplexer
|
|
controllers. It provides the same API as Linux and mux drivers should
|
|
be portable with a minimum effort.

MMIO register bitfield-controlled Multiplexer controller.
|
|
|
|
The driver builds multiplexer controllers for bitfields in a syscon
|
|
register. For N bit wide bitfields, there will be 2^N possible
|
|
multiplexer states.
