^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) - reg: The base address of the UART register bank.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) - interrupts:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) index 0: an interrupt specifier for the UART controller itself
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) index 1: optional, an interrupt specifier with edge sensitivity on Rx pin to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) support Rx in-band wake up. If one would like to use this feature,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) one must create an addtional pinctrl to reconfigure Rx pin to normal
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) GPIO before suspend.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) - clock-names:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) - "baud": The clock the baudrate is derived from
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) - "bus": The bus clock for register accesses (optional)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) For compatibility with older device trees an unnamed clock is used for the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) baud clock if the baudclk does not exist. Do not use this for new designs.
