This patch series implements driver for lan966 flexcom multiplexer.
Converts atmel-flexcom.txt bindings to yaml format and add new
compatible string for lan966 flexcom.
This patch also adds dt bindings for lan966 flexcom multiplexer.
v1 -> v2:
- addressed comments for atmel,flexcom.yaml.
- added child node and its parameters properly in flexcom bindings.
- added ref to mux-consumer.yaml.
- added ref to mux-controller.yaml in lan966-flx-mux.yaml
- added MODULE() stuff in lan966 mux driver.

dt-bindings: mfd: atmel,flexcom: Convert to json-schema
dt-bindings: mfd: atmel,flexcom: Add lan966 compatible string and mux
properties
dt-bindings: mux: Add lan966 flexcom mux controller
mux: lan966: Add support for flexcom mux controller
