[alsa-devel] [PATCH 00/11] ARM/ASoC: OMAP McBSP device tree support

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).
Peter Ujfalusi (11):
ARM/ASoC: omap-mcbsp: Move OMAP2+ clock parenting code to ASoC driver
ARM: OMAP2+: McBSP: Do not create legacy devices when booting with DT
ARM: OMAP: mcbsp: Enable FIFO use for OMAP2430
ARM: OMAP: board-am3517evm: Configure McBSP1 CLKR/FSR signal source
ASoC: am3517evm: Do not configure McBSP1 CLKR/FSR signal muxing
ARM/ASoC: omap-mcbsp: Remove CLKR/FSR mux configuration code
ASoC: omap-mcbsp: Sidetone: Use SIDLE bits in SYSCONFIG register to
select noidle mode
ARM: OMAP3: Remove callback for McBSP sidetone ICLK workaround
ASoC: omap-mcbsp: Remove unused defines
ASoC: omap-mcbsp: Remove cpu_is_omap* checks from the code
ASoC: omap-mcbsp: Add device tree bindings
