2021-12-20ASoC: meson: Use dev_err_probe() helperKuninori Morimoto1-12/+4
Use the dev_err_probe() helper, instead of open-coding the same operation. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/20211214020843.2225831-17-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
2021-04-07ASoC: meson: axg-fifo: add NO_PERIOD_WAKEUP supportJerome Brunet1-5/+6
On the AXG family, the fifo irq is not necessary for the HW to operate. It is just used to notify that a period has elapsed. If userpace does not care for these wakeups (such as pipewire), we are just wasting CPU cycles. Add support for NO_PERIOD_WAKEUP and disable irq when they are no needed.

2019-12-18ASoC: meson: axg-fifo: relax period size constraintsJerome Brunet1-4/+4
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.

2019-12-18ASoC: meson: axg-fifo: improve depth handlingJerome Brunet1-2/+17
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.

2019-12-18ASoC: meson: axg-fifo: fix fifo threshold setupJerome Brunet1-2/+25
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>

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.
