Hi This patch series adds support for the Sound Interface Unit (SIU), found on several SuperH SoCs, including sh7722, sh7343, sh7354, sh7367. The driver supports playback and capture at various bitrates, mono and stereo, so far only tested with an I2S codec, support for the PCM (SND_SOC_DAIFMT_LEFT_J) is also included. The hardware also supports S/PDIF, but including support for it would require more work and testing on a suitable hardware platform. The SIU engine includes a DSP, that has to be programmed separately. The driver uses the standard request_firmware() API to load the program and data. This patch series also requires the earlier [PATCH] sh: support SIU sourcing from external clock on sh7722 (http://www.spinics.net/lists/linux-sh/msg04075.html) patch for proper functionality. Comments welcome.
