The TLV320DAC3100 Audio DAC has 25 built-in digital audio processing blocks
(PRBs). Each of these PRBs has a static filter structure with programmable
coefficients. Once a PRB is selected for use by the DAC, its filter
coefficients can be configured via a dedicated set of registers.
Define a new optional firmware which can be loaded by the TLV320DAC driver.
This firmware describes a full set of filter coefficients for all blocks
used by the various PRBs.
The firmware's binary format is heavily inspired by the one used in the
peb2466 driver. It includes a version marker to allow for potential
evolutions of the format.
Note that adaptive filtering is not supported i.e. filter coefficients are
loaded once before power-on and then cannot be changed while the DAC is
powered. This is why only page A coefficients are modified. Page B
coefficients are only used for adaptive filtering.

The devm_clk_get_enabled() helpers:
- call devm_clk_get()
- call clk_prepare_enable() and register what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code and avoids the calls to clk_disable_unprepare().

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.
Although that is not the case here, it is seems best to use ';'
unless ',' is intended.
Found by inspection.
No functional change intended.

Merge series from amergnat@baylibre.com:
This serie aim to add the following audio support for the Genio 350-evk:
- Playback
- 2ch Headset Jack (Earphone)
- 1ch Line-out Jack (Speaker)
- 8ch HDMI Tx
- Capture
- 1ch DMIC (On-board Digital Microphone)
- 1ch AMIC (On-board Analogic Microphone)
- 1ch Headset Jack (External Analogic Microphone)
Of course, HDMI playback need the MT8365 display patches [1] and a DTS
change documented in "mediatek,mt8365-mt6357.yaml".
The period size represents the size of the DMA descriptor. To ensure all
DMA descriptors start from a well-aligned address, the period size must
be divided by (sample size * maxburst), not just by maxburst.
This adjustment allows for computing a higher maxburst value, thereby
increasing the performance of the DMA transfer.
Previously, snd_pcm_lib_period_bytes() returned 0 because the runtime HW
parameters are computed after the hw_params() callbacks are used.
To address this, we now use params_*() functions to compute the period
size accurately. This change optimizes the DMA transfer performance by
ensuring proper alignment and efficient use of maxburst values.
[andrei.simion@microchip.com: Reword commit message and commit title.
Add macros with values for maximum DMA chunk size allowed.
Add DMA_BURST_ALIGNED preprocessor function to check the alignment of the
DMA burst]

The Nanopc-T6 board does contain some devicetree errors, that came to
light with recent changes to the board.
Support multiple endpoints on TLV320AIC32x4 codec port when
used in of_graph context.
This patch allows to share the codec port between two CPU DAIs.
Example:
Custom STM32MP157C board uses TLV320AIC32x4 audio codec. This codec
is connected to two serial audio interfaces, which are configured
either as rx or tx.
>From AsoC point of view the topolgy is the following:
// 2 CPU DAIs (SAI2A/B), 1 Codec (TLV320AIC32x4)
Playback: CPU-A-DAI(slave) -> (master)CODEC-DAI/port0
Record: CPU-B-DAI(slave) <- (master)CODEC-DAI/port0
In the DT two endpoints have to be associated to the codec port:
tlv320aic32x4_port: port {
tlv320aic32x4_tx_endpoint: endpoint@0 {
remote-endpoint = <&sai2a_endpoint>;
};
tlv320aic32x4_rx_endpoint: endpoint@1 {
remote-endpoint = <&sai2b_endpoint>;
};
};
However, when the audio graph card parses the codec nodes, it expects
to find DAI interface indexes matching the endpoints indexes.
The current patch forces the use of DAI id 0 for both endpoints,
which allows to share the codec DAI between the two CPU DAIs
for playback and capture streams respectively.
