Hello,
in order to be able to add DT support for the McBSP driver which is used on all
OMAP platforms (OMAP1/2/3/4/5) I needed to make some cleanups to the stack:
- Removing callbacks used by the driver for
- clock re-parenting (code moved to sound driver)
- FSR/CLKR mux configuration (from now on it need to be done at board level)
This mux is board specific and depends on the wiring.
- OMAP3 sidetone ICLK workaround has been reimplemented using the SYSCONFIG
register's SIDLEMODE filed to prevent ICLK gating while ST is running.
- Replaced the cpu_is_omap* checks with future proof check.
- The FIFO was not enabled on OMAP2430 SoC
It has been tested on BeagleBoard (with legacy and DT boot).
The series changes McBSP related files mostly. It would be great if the whole
series could go via audio tree (if the patches are OK and it is fine by Tony).
Regards,
Peter
