[Sound-open-firmware] [PATCH 1/2] dai: add stream_format to dai_data for codec stream
by Keyon Jie 29 Dec '16

29 Dec '16

Adding stream_format to indicate the stream format that the dai buffer is using, which will be used for volume copy functions mapping.

[Sound-open-firmware] [PATCH 1/4] pipeline: set up static buffers using platform macros.
by Liam Girdwood 28 Dec '16

Use period frames instead of period size in bytes. This makes the pipeline configuration less ambiguous and also allows for host, dai and internal frame sizes to be defined.

[Sound-open-firmware] [PATCH v2 0/7] SSP: baytrail 24 bits support
by Keyon Jie 23 Dec '16

23 Dec '16

This series is created to change the SSP format setting for both Tx and Rx, and it is verified on MinnowMax + ALC5651 codec with I2S stereo both SSP_CLK_EXT and SSP_CLK_AUDIO mode. Changes including: 1. change ssp clock from 25M to 19.2M; 2. add 16bit <==> 24bit volume converting functions; 3. change to get dai format from host; 4. change to get ssp stream format from host; 5. remove the shim SSP divider and use SSCR0.SCR for BCLK generating. changes from v1: 1. change to make dai format configurable; 2. change to make ssp stream format configurable; 3. clean shim SSP divider code; 4. optimize volume copy functions. Keyon Jie (7): ssp: switch to use SCR for BCLK generation. platform: switch default ssp clock to 19.2M volume: add 16bit<==>24bit volume copy function and mapping ssp: switch dai format form PCM B mode to normal I2S mode intel-ipc: get dai format from ipc dai: add stream_format to dai_data for codec stream intel-ipc: change to get ssp stream format from ipc src/audio/dai.c | 10 ++ src/audio/volume.c | 119 ++++++++++++--------- src/drivers/ssp.c | 5 +- src/include/reef/dai.h | 1 + src/include/reef/stream.h | 20 ++++ src/include/uapi/intel-ipc.h | 2 + src/ipc/intel-ipc.c | 32 +++--- src/platform/baytrail/include/platform/platform.h | 10 +- src/platform/baytrail/platform.c | 120 ---------------------- 9 files changed, 126 insertions(+), 193 deletions(-) -- 2.7.4

[Sound-open-firmware] [PATCH] dma: Add support for callback DMA reload.
by Liam Girdwood 22 Dec '16

22 Dec '16

Add support to immediately reload the DMA during a DMA transfer completion callback. This allows components to respond quickly to any physical DMA copy updates i.e. period split over two non continuous physical host pages.

[Sound-open-firmware] [PATCH 0/8] SSP: baytrail 24 bits support
by Keyon Jie 20 Dec '16

20 Dec '16

This series is created to change the SSP format setting for both Tx and Rx, and it is verified on MinnowMax + ALC5651 codec with I2S stereo both SSP_CLK_EXT and SSP_CLK_AUDIO mode. Changes including: 1. change ssp clock from 25M to 19.2M; 2. add 16bit <==> 24bit volume converting functions; 3. switch to use I2S mode(more common on host side); 4. change ssp stream format to 24 bits; 5. remove the usage of shim SSP divider and use SSCR0.SCR for BCLK generating. Keyon Jie (8): platform: ssp divider: read the ssp clock directly platform: switch default ssp clock to 19.2M volume: add 16bit<==>24bit volume copy function and mapping ssp: switch dai format form PCM B mode to normal I2S mode platform: add divider m/n setting for 50 bclk_fs dai: add stream_format to dai_data for codec stream ssp: change stream format to S24_4LE ssp: switch to use SCR for BCLK src/audio/dai.c | 9 +++++ src/audio/volume.c | 43 +++++++++++++++++++++++ src/drivers/ssp.c | 4 +-- src/ipc/intel-ipc.c | 19 +++------- src/platform/baytrail/include/platform/platform.h | 8 +++-- src/platform/baytrail/platform.c | 10 ++---- 6 files changed, 66 insertions(+), 27 deletions(-) -- 2.7.4

[Sound-open-firmware] [PATCH] pipeline: clear buffer content to 0s on new
