ASoC: meson: axg-fifo: relax period size constraints

2019-12-18T20:01:34+00:00

Now that the fifo depths and thresholds are properly in the axg-fifo driver, we can relax the constraints on period. As long as the period is a multiple of the fifo burst size (8 bytes) things should be OK.

ASoC: meson: axg-fifo: improve depth handling

2019-12-18T20:01:15+00:00

Let the fifo driver parse the fifo depth from DT. Eventually all DT should have this property. Until it is actually the case, default to 256 bytes if the property is missing. 256 bytes is the size of the smallest fifo on the supported SoCs. On the supported SoC, fifo A is usually bigger than the other ones. With depth known, we can improve the usage of the fifo and adapt the setup of request threshold.

ASoC: meson: axg-fifo: fix fifo threshold setup

2019-12-18T20:00:24+00:00

On TODDR sm1, the fifo threshold register field is slightly different compared to the other SoCs. This leads to the fifo A being flushed to memory every 8kB. If the period is smaller than that, several periods are pushed to memory and notified at once. This is not ideal. Fix the register field update. With this, the fifos are flushed every 128B. We could still do better, like adapt the threshold depending on the period size, but at least it consistent across the different SoC/fifos Fixes: 5ac825c3d85e ("ASoC: meson: axg-toddr: add sm1 support") Reported-by: Alden DSouza Signed-off-by: Jerome Brunet Link: https://lore.kernel.org/r/20191218172420.1199117-2-jbrunet@baylibre.com Signed-off-by: Mark Brown

ASoC: meson: Use managed buffer allocation

2019-12-11T16:43:20+00:00

Clean up the driver with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped.

ASoC: meson: Drop superfluous ioctl PCM ops

ASoC PCM core deals the empty ioctl field now as default. Let's kill the redundant lines. Cc: Jerome Brunet Cc: Kevin Hilman Signed-off-by: Takashi Iwai Acked-by: Jerome Brunet Link: https://lore.kernel.org/r/20191210145406.21419-11-tiwai@suse.de Signed-off-by: Mark Brown

ASoC: meson: remove snd_pcm_ops

ASoC: meson: tdmin: expose all 16 inputs

2019-09-05T17:17:13+00:00

The TDMIN component, as it, has a maximum of 16 input. Depending on the SoC, these may not all be connected. Instead of decribing only the connected inputs of each SoC, describe them all and let ASoC routing do the rest.
