ASoC: meson: axg-toddr: add support for spdifin backend add IEC958_SUBFRAME_LE to the list of format accepted by the fifo frontend. As opposed to what was initially noted in the toddr dai driver, the spdifin does not place the msb at bit 28, it just output a whole spdif subframe. Placing the msb at bit 28 in the toddr driver just filters out the parity, user, channel status and validity bits. It is better to just provide the whole spdif subframe to the userspace and let the iec958 plugin deal with it.

ASoC: meson: axg-fifo: fix fifo threshold setup 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 <aldend@google.com> Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Link: https://lore.kernel.org/r/20191218172420.1199117-2-jbrunet@baylibre.com Signed-off-by: Mark Brown <broonie@kernel.org>
