2023-01-31ASoC: meson: use helper functionKuninori Morimoto
Current ASoC has many helper function. This patch use it.

2021-03-31ASoC: meson: axg-tdmout: remove useless assignmentPierre-Louis Bossart
cppcheck complains about potential null pointer dereference but it's rather an unnecessary assignment to NULL before walking through a list.

2020-07-30ASoC: meson: axg-tdm-formatters: fix sclk inversionJerome Brunet
After carefully checking, it appears that both tdmout and tdmin require the rising edge of the sclk they get to be synchronized with the frame sync event (which should be a rising edge of lrclk). TDMIN was improperly set before this patch. Remove the sclk_invert quirk which is no longer needed and fix the sclk phase.

On the sm1, the TDMOUT number of input is extended and the the gain enable bit moved to accommodate this extension Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Link: https://lore.kernel.org/r/20190905120120.31752-9-jbrunet@baylibre.com Signed-off-by: Mark Brown <broonie@kernel.org>
2019-06-13ASoC: meson: axg-tdmout: right_j is not supportedJerome Brunet
Right justified format is actually not supported by the amlogic tdm output encoder. Fixes: c41c2a355b86 ("ASoC: meson: add tdm output driver") Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-05ASoC: meson: axg-tdmout: add g12a supportJerome Brunet
The axg tdmout driver just need a different skew offset to operate correctly on the g12a SoC family. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-05ASoC: meson: axg-tdm-formatter: rework quirks settingsJerome Brunet
The g12a tdmout requires a different signal skew offset than the axg. With this change, the skew offset is added as a parameter of the tdm formatters to prepare the addition of the g12a support. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-07-20ASoC: meson: add tdm output driverJerome Brunet
Add Amlogic's axg tdm output driver which pulls data from FRDDR fifo and produce the TDM signals for 4 output lanes. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
