The SAI and XCVR have the timestamp counters and bit counters, which can be used by software to track the progress of the transmitter and receiver. They can also be used to calculate the relative frequency of the bit clock against the bus interface clock.
Changes in v2: - remove arrays of enums, define transmit_tstmp_enum and receive_tstmp_enum separately. - remove __bf_shf(), define the XXX_SHIFT macros.
