This is intended to put both the SoC and Codec into slave modes. By default un-patched SoC and Codec drivers will return -EINVAL if they aren't enabled and tested for this mode. soc-dia.h has the new SND_SOC_DAIFMT_IBM_IFM definition set as : #define SND_SOC_DAIFMT_IBM_IFM (5 << 12) /* IC clk & FRM master */ The cs42xx8 codec driver is enabled for this mode and so too is the BCM2835 SoC driver. This forms a chain : bcm2835<=>IC<=>cs42xx8 where the IC is bit and frame master. Matt Flax (3): ASoC : Add an IC bit and frame master mode (SoC and Codec slave). ASoC: cs42xx8: allow IC master mode.
