ASoC: meson: add axg fifo base driver 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.

ASoC: meson: add axg frddr driver Add the playback memory interface of Amlogic's axg SoCs. This device pulls data from DDR to an internal FIFO. This FIFO is then used to feed TDM and SPDIF Output devices.

ASoC: meson: add axg toddr driver Add the capture memory interface of Amlogic's axg SoCs. TDM, SPDIF or PDM input devices place audio samples inside this FIFO.

ASoC: meson: add tdm formatter base driver 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.

ASoC: meson: add tdm interface driver 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.
