2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-08-25ASoC: rt5677: Allow arbitrary block read/write via SPIBen Zhang
Added rt5677_spi_read() and refactored rt5677_spi_write() so that an arbitrary block in the DSP address space can be read/written via SPI. For example, this allows us to load an ELF DSP firmware with sparse sections, and stream audio samples from DSP ring buffer.

2014-10-23ASoC: rt5677: fix rt5677 spi driver buildBen Zhang
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.

2014-10-20ASoC: rt5677: Support DSP function for VAD applicationOder Chiou
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>
