Following features are not described in the bindings:
- The McBSP uses an internal sample rate generator to provide bit clock or frame clock. This sample rate generator can be programmed to be driven by McBSP's internal clock source or by an external clock source (located on CLKS pin).
- McBSP can be configured in 'free-running' mode so that its serial clocks will continue to run during emulation halt.
- McBSP can generate a SYNCERR when unexpected frame pulses are detected
Add an optional clock item that allows to select an external clock as sample rate generator's input.
Add a 'ti,disable-free-run' flag to disable the free-running mode. This mode is selected by default by the driver that's why I add a disabling flag instead of an enabling one.
Add a 'ti,enable-sync-err' flag to enable SYNCERR generation when unexpected frame pulses are detected.
