[PATCH v4 1/8] dt-bindings: interrupt-controller: Add Realtek RTD1195/RTD1295 mux

["Andreas Färber" <afaerber@suse.de>]

Add binding for Realtek RTD1295 and RTD1195 IRQ mux.

Acked-by: Rob Herring <robh@kernel.org>
[AF: Converted to YAML schema]
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
 v3 -> v4:
 * Squashed RTD1195
 * Converted to YAML schema
 * Renamed file from realtek,rtd119x-mux to realtek,rtd1195-mux
 
 v2 -> v3:
 * Renamed non-iso irq mux to "misc" for clarity

 v1 -> v2:
 * Dropped reference to common interrupt.txt bindings (Rob)
