ASoC: clarify Codec2Codec params
Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
ASoC is supporting Codec2Codec, but its parameter name is
"params" and "num_params" which are very unclear naming.
This patch-set clarifies it by replacing to c2c_params / num_c2c_params.

ASoC: samsung: switch to use c2c_params instead of params
ASoC is now using c2c_params instead of params. This patch replace it.
num_c2c_params (was num_params) was not mandatory before,
but let's set it by this patch.

Up to date documentation for reSpeaker products can be found in Seeed Studio Wiki!
Coherence
Estimate the magnitude squared coherence using Welch’s method.
Note: 'CO 1-2' means the coherence between channel 1 and channel 2.
# How to get the coherence of the captured audio(a.wav for example).
sudo apt install python-numpy python-scipy python-matplotlib
python tools/coherence.py a.wav
# Requirement of the input audio file:
- format: WAV(Microsoft) signed 16-bit PCM
- channels: >=2
uninstall seeed-voicecard
If you want to upgrade the driver , you need uninstall the driver first.
pi@raspberrypi:~/seeed-voicecard $ sudo ./uninstall.sh
...
------------------------------------------------------
Please reboot your raspberry pi to apply all settings
Thank you!

Enjoy !
Technical support
For hardware testing purposes we made a Rasperry Pi OS 5.10.17-v7l+ 32-bit image with reSpeaker drivers pre-installed, which you can download by clicking on this link.
We provide official support for using reSpeaker with the following OS:
- 32-bit Raspberry Pi OS
- 64-bit Raspberry Pi OS
And following hardware platforms:
- Raspberry Pi 3 (all models), Raspberry Pi 4 (all models)
Anything beyond the scope of official support is considered to be community supported. Support for other OS/hardware platforms can be added, provided MOQ requirements can be met.
If you have a technical problem when using reSpeaker with one of the officially supported platforms/OS, feel free to create an issue on Github. For general questions or suggestions, please use Seeed forum.
