^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) * SiRF SoC USP module
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) - compatible: "sirf,prima2-usp-pcm"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) - reg: Base address and size entries:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) - dmas: List of DMA controller phandle and DMA request line ordered pairs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) - dma-names: Identifier string for each DMA request line in the dmas property.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8)   These strings correspond 1:1 with the ordered pairs in dmas.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)   One of the DMA channels will be responsible for transmission (should be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)   named "tx") and one for reception (should be named "rx").

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - clocks: USP controller clock source
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) - pinctrl-names: Must contain a "default" entry.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) - pinctrl-NNN: One property must exist for each entry in pinctrl-names.
