- reg: The base address of the UART register bank.
-- interrupts: A single interrupt specifier.
+- interrupts:
+ index 0: an interrupt specifier for the UART controller itself
+ index 1: optional, an interrupt specifier with edge sensitivity on Rx pin to
+ support Rx in-band wake up. If one would like to use this feature,
+ one must create an addtional pinctrl to reconfigure Rx pin to normal
+ GPIO before suspend.
- clocks : Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
