2020-07-30ASoC: meson: axg-tdm-formatters: fix sclk inversionJerome Brunet1-5/+6
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.

2019-07-03ASoC: meson: axg-tdm-formatter: add resetJerome Brunet1-0/+29
Add the optional reset line handling which is present on the new SoC families, such as the g12a. Triggering this reset is not critical but it helps solve a channel shift issue on the g12a.

2019-04-05ASoC: meson: axg-tdm-formatter: rework quirks settingsJerome Brunet1-2/+4
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 formatter base driverJerome Brunet1-0/+381
Add Amlogic's axg TDM core driver. On this SoC, tdm is bit more complex than usual, mainly because the different TDM input decoders can be attached to any of TDM pad interface, including the output pads. For the this, TDM on this SoC is modeled like this: - TDM interface provides the DAIs the codecs will be attached to. The main responsibility of this driver is to manage the pad format and the TDM clock rates. - TDM Formatters: These are the entities which are actually dealing with the TDM signal. TDMOUT produce a TDM signal from the audio sample provided by FRDDR using the clocks provided the TDM interface. TDMIN feeds TODDR with audio sample using the clocks and TDM signal provided by the TDM Interface. - TDM Streams: This provides the link between 1 DAI stream of the TDM interface and one (or more) TDM formatters. This driver provides the TDM formatter and TDM stream operations. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
