2019-07-31ASoC: meson: g12a-tohdmitx: override codec2codec paramsJerome Brunet1-18/+16
So far, forwarding the hw_params of the input to output relied on the .hw_params() callback of the cpu side of the codec2codec link to be called first. This is a bit weak. Instead, override the stream params of the codec2codec to link to set it up correctly.

2019-06-13ASoC: meson: axg-tdm: fix sample clock inversionJerome Brunet1-1/+1
The content of SND_SOC_DAIFMT_FORMAT_MASK is a number, not a bitfield, so the test to check if the format is i2s is wrong. Because of this the clock setting may be wrong.

2019-06-10ASoC: meson: axg-card: fix null pointer dereference in clean upJerome Brunet1-2/+4
When using modern dai_link style, we must first make sure the struct snd_soc_dai_link_component exists before accessing its members. In case of early probe deferral, some of the '.cpus' or '.codecs' may not have been allocated yet. Check this before calling of_node_put() on the structure member.

Add basic support for codec-to-codec link in the axg sound card. The cpu side of these links is expected to properly set the hw_params and format of the link.

2019-05-16ASoC: meson: axg-card: set link name based on link node nameJerome Brunet1-5/+7
So far the link names of the axg sound card was derived from the cpu name of the link. Since the dai link must be unique, it works as long as a device does not provide more than one cpu dai. However, the 'tohdmitx' does provide 2 dais used as cpu on codec-to-codec links Instead of cpu name, use the node name of the dai link.

2019-04-05ASoC: meson: axg-frddr: add g12a supportJerome Brunet1-3/+140
On the axg, frddr could only be connected to 1 downstream element, so the playback was possible on 1 interface only at a time. On the g12a, the frddr may connect and wait for the request of up to 3 downstream elements. With this, it possible for single playback to be played on several interfaces at the same time. Like the toddr fifo, the g12a frddr also need to take care of resetting the read pointer to the initial fifo address when preparing a playback.

2019-04-05ASoC: meson: axg-toddr: add g12a supportJerome Brunet1-0/+53

2018-12-13ASoC: meson: axg-toddr: add support for spdifin backendJerome Brunet2-11/+7
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.

Add Amlogic's axg TDM interface driver. This driver manages the format and clocks provided on the pads. On this SoC, each stream direction provides 4 serial lanes. This makes a maximum of 8 channels in i2s modes and 128 channels in DSP modes. While each lanes operate on the same slot number (same bit clock), they may have different TDM masks.

2018-07-20ASoC: meson: add tdm formatter base driverJerome Brunet5-0/+500
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>
