+ McBSP will insert a blank period (high-impedance period) before the first
+ data bit. This can be used to interface to T1-framing devices.

+ ti,T1-framing-rx:
+ $ref: /schemas/types.yaml#/definitions/flag
+ description:
+ If the property is present, rx data delay is set to 2 bit clock periods.
+ McBSP will discard the bit preceding the data stream (called framing bit).
+ This can be used to interface to T1-framing devices.
