ad6bb3067c ASoC: cs42l51: add multi endpoint support
Support multiple endpoints on cs42L51 codec port
when used in of_graph context.

This patch allows to share the codec port between two CPU DAIs.

Example:

STM32MP157C-DK2 board uses CS42L51 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 (CS42L51)
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:
cs42l51_port: port {
	cs42l51_tx_endpoint: endpoint@0 {
		remote-endpoint = <&sai2a_endpoint>;
	};
	cs42l51_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.

96c3bb0023 ASoC: tlv320aic32x4: Dynamically Determine Clocking
The existing code uses a static lookup table to determine the
settings of the various clock devices on board the chip.  This is
limiting in a couple of ways.  First, this doesn't allow for any
master clock rates other than the three that have been
precalculated.  Additionally, new sample rates are difficult to
add to the table.  Witness that the chip is capable of 192000 Hz
sampling, but it is not provided by this driver.  Last, if the
driver is clocked by something that isn't a crystal, the
upstream clock may not be able to achieve exactly the rate
requested in the driver.  This will mean that clocking will be
slightly off for the sampling clock or that it won't work at all.

This patch determines the settings for all of the clocks at
runtime considering the real conditions of the clocks in the
system.  The rules for the clocks are in TI's SLAA557 application
guide on pages 37, 51 and 77.

d90ba6c8b5 ASoC: da7219: Expose BCLK and WCLK control through CCF
For the purposes of platforms which use the codec as DAI clock
master for the CPU and other codec devices, there is the need to
not only expose the clock gating of BCLK and WCLK but also the
ability to set those rates without going through the ASoC APIs.

To make this possible, the previous CCF implementation in the
driver has been extended to separate BCLK and WCLK out. WCLK is
the parent clock to BCLK, and is also the clock gate for both.
BCLK in HW is a factor/multiplier of WCLK so derives from whatever
SR is chosen for WCLK, hence the need to make it a child of WCLK
for the purposes of CCF. Enabling/disabling either BCLK or WCLK
will result in clocks being ungated/gated accordingly. To simplify
matters, these clocks can only be configured if the codec is set
as master, otherwise CCF control is disallowed.

03d0aa4d4f ASoC:hdac_hda:use correct format to setup hda codec
The current implementation of the hdac_hda codec results in zero-valued
samples on capture and noise with headset playback when SOF is used on
platforms with an on-board HDaudio codec. This is root-caused to SOF
using be_hw_params_fixup, and the prepare() call using invalid runtime
fields to determine the format.

This patch moves the format handling to the hw_params() callback, as
done already for hdac_hdmi, to make sure the fixed-up information is
taken into account but keeps the codec initialization in prepare() as
the stream_tag is only available at that time. Moving everything in the
prepare() callback is possible but the code is less elegant so this
two-step solution was chosen.

The solution was tested with the SST driver with no regressions, and all
the issues with SOF playback and capture are solved.

bbf62563d8 ASoC: hdmi-codec: avoid limiting params->msbits in hw_params()
Limiting the value of the passed in params->msbits in the hw_params()
callback is redundant on three counts:

1. We already specify in the DAI driver that we can only handle up to
   24 bits.  This means msbits will be limited to 24 via the ALSA
   constraints imposed by the ASoC core, unless we have multiple codecs
   that can handle more bits.

2. Nothing in our hw_params() implementation uses this value.

3. The copy of the params that we are passed by the ASoC core never
   reads back the msbits value.

Consequently, this code is unnecessary and does nothing useful.  Remove
it.
