ASoC: omap-mcbsp: Single function CLKR/FSR source mux configuration
Use single function for the CLKR/FSR mux configuration. OMAP2/3 has 6 pin configuration on McBSP1 instance, while on OMAP4 McBSP4 instance have the 6 pin configuration so the omap2_mcbsp1_mux_* is not correct name for all support OMAP versions Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Acked-by: Jarkko Nikula <jarkko.nikula@bitmer.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@ti.com>
