2019-02-06ASoC: meson: Drop superfluous PCM preallocation error checksTakashi Iwai1-3/+4
snd_pcm_lib_preallocate_pages() and co always succeed, so the error check is simply redundant. Drop it. Reviewed-by: Jaroslav Kysela <perex@perex.cz> Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-12-13ASoC: meson: fix do_div warning in spdifinJerome Brunet1-2/+2
Even if this spdif input driver is only supposed to be used on 64bits platform, there is possible problem with 32bits and do_div, as reported by the kbuild robot. Just fix it.

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 the axg sound card to handle the specifities of the axg audio sub system.

2018-07-20ASoC: meson: add tdm interface driverJerome Brunet4-0/+552
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. This requires to provide a function to let the card set the 4 masks, in lieu of the usual set_tdm_slots() callback of the dai driver.

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>

2018-07-18ASoC: meson: add axg frddr driverJerome Brunet3-0/+150

2018-07-18ASoC: meson: add axg fifo base driverJerome Brunet4-0/+434
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.
