Subject: [PATCH 0/2] Add support for new property 'mux-reg-masks-state' for mmio mux

This series extends mmio-mux driver's capability to configure driver in
with extended property.

In current driver implementation (mmio.c), driver is parsing register's
offset, mask and value from two different device tree property. In order
to configure mux register, these two properties should be synchronized
with each other, and this constraint makes it complex to modify or add 
further entries for that memory region. To simplify this, add support for 
a new property, "mux-reg-masks-state", which allows offset, mask, and 
value to be specified together as a tuple, and remove the above
constraint.

This series is based on linux next tagged next-20250604.
