ASoC: wm*: Remove now redundant non_legacy_dai_naming flag
The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

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

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.
