2020-06-24ASoC: meson: add missing free_irq() in error pathPavel Machek (CIP)1-2/+8
[ Upstream commit 3b8a299a58b2afce464ae11324b59dcf0f1d10a7 ] free_irq() is missing in case of error, fix that.

2020-02-11ASoC: meson: axg-fifo: fix fifo threshold setupJerome Brunet1-2/+25
commit 864cee90d4bd870e5d5e5a0b1a6f055f4f951350 upstream. 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> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-04-05ASoC: meson: axg-fifo: add g12a supportJerome Brunet1-3/+31
The g12a fifos gained the ability to set the initial address of the pointer within the buffer, instead of defaulting to the buffer start address. It is not very useful to us (yet) but we need to put a copy the buffer start address in the related register for the fifo to work properly on the g12a SoC family Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2018-07-18ASoC: meson: add axg fifo base driverJerome Brunet1-0/+341
Amlogic's axg SoCs have two types of fifos which are the memory interfaces of the audio subsystem. FRDDR provides the playback interface while TODDR provides the capture interface. The way these fifos operate is very similar. Only a few settings are specific to each. They implement the same pcm driver here and the specifics of each will be dealt with the related DAI driver.
