* ASoC: rt5677: fix rt5677 spi driver buildBen Zhang2014-10-231-0/+2
| | | | | | | | | | | Create a separate module for rt5677 spi driver. Without this patch, the build fails due to multiple defs of 'init_module' and 'cleanup_module'. module_spi_driver() defines its own module, so it can't be part of the rt5677 module.

* ASoC: rt5677: Support DSP function for VAD applicationOder Chiou2014-10-201-0/+128
The ALC5677 has a programmable DSP, and there is a SPI that is dadicated for DSP firmware loading. Therefore, the patch includes a SPI driver for writing the DSP firmware. The VAD(Voice Activaty Detection) has be implemented and use the DSP to recognize the key phase. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
