ASoC: Add support for the Analog Devices AXI-I2S core
This patch adds support for the AXI-I2S softcore. The core implements a simple bidirectional I2S transceiver and is used by Analog Devices in some of their reference designs for various FPGA platforms. The driver uses the generic PCM dmaengine driver for its PCM. The only restriction is that we need to set the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag as the dmaengine driver for the DMA core (PL330) that is used with this core has no residue reporting capabilities yet. This will be fixed in the future though. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
