ASoC: Add support for BCM2835
This driver adds support for digital audio (I2S) for the BCM2835 SoC that is used by the Raspberry Pi. External audio codecs can be connected to the Raspberry Pi via P5 header. It relies on cyclic DMA engine support for BCM2835. Signed-off-by: Florian Meier <florian.meier@koalo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
