2017-05-14ASoC: rt5514: Add more width and channels support in the TDM modeOder Chiou1-0/+6
This patch adds more width and channels support in the TDM mode. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-10-25ASoC: rt5514: Add the DMIC initial delay to wait it ready.Oder Chiou1-0/+2
Due to the DMIC that needs time to initial after the MCLK is provided, the field of delay time is implemented by the platform data. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-09-12ASoC: rt5514: make the volume TLV to match the units 0.01dBOder Chiou1-2/+2
The volume have a step of 0.375dB, but TLV uses the units 0.01dB. It should be changed to a step of 0.75dB to match the units of TLV. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-06-22ASoC: rt5514: Add the MCLK handlingOder Chiou1-0/+3
The patch adds the control of MCLK that depends on the status of DAPM. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-06-07ASoC: rt5514: add rt5514 SPI driverOder Chiou1-0/+4
The device has multiple control interfaces, I2C and SPI. The I2C interface mainly controls the register settings of codec. The SPI interface is in order to provide the high speed transmission of data. For example, high bandwidth memory read/write of DSP. The patch adds the rt5514 SPI driver for loading the firmware of DSP and retrieving the voice data from DSP after the system is waked up by specific voice.

2016-02-03ASoC: rt5514: add rt5514 codec driverOder Chiou1-0/+252
This is the initial codec driver for rt5514. The codec includes a low power DSP for voice wake up. The register address is incremental by 4 in the DSP memory map. In order to recover the codec settings in the codec mode and manipulate the DSP mode for voice wake up, we use the multi-level register map. One is for ALSA API in codec mode that can be recovered by cache before recording. Another is for DSP related settings that can be accessed with 32bit address of the DSP in the application of voice wake up.
