SAI supports these operation modes:
- asynchronous mode Both Tx and Rx are set to be asynchronous.
- synchronous mode (Rx sync with Tx) Tx is set to be asynchronous, Rx is set to be synchronous.
- synchronous mode (Tx sync with Rx) Rx is set to be asynchronous, Tx is set to be synchronous.
- synchronous mode (Tx/Rx sync with another SAI's Tx)
- synchronous mode (Tx/Rx sync with another SAI's Rx)
This seems to conflict with something else on my branch - not checked what. Can you take a look please?
+Note: +- If both fsl,sai-asynchronous and fsl,sai-synchronous-rx are absent, the
- default synchronous mode (sync Rx with Tx) will be used, which means both
- transimitter and receiver will send and receive data by following clocks
- of transimitter.
+- fsl,sai-asynchronous will be ignored if fsl,sai-synchronous-rx property is
- already present.
Might be worth printing an error here.
