Add ES7210 audio ADC driver for NuttX implementing the audio lower-half interface. Supports 4-channel recording via I2S with configurable sample rate, bit depth, and mic gain. - drivers/audio/es7210.c: Codec driver using LPWORK for async buffer management, I2C register access, and NuttX audio buffer management - drivers/audio/es7210.h: Internal register definitions and macros - include/nuttx/audio/es7210.h: Public header with platform config structure and es7210_initialize() API - drivers/audio/Kconfig, Make.defs, CMakeLists.txt: Build system integration for CONFIG_AUDIO_ES7210 Key implementation details: - ES7210_SDP_NORMAL (normal I2S) instead of TDM, matching NuttX I2S standard Philips mode - ES7210_ADC_PGA_POWER_ON bit in gain registers REG43-46, required for analog front-end amplifier power-on - 50ms startup delay in es7210_start for codec clock stabilization - I2S_IOCTL(AUDIOIOC_STOP) in es7210_stop to notify I2S layer, preventing DMA from running without buffers after stop Signed-off-by: wangjianyu3 <wangjianyu3@xiaomi.com>

This is a params for fake audio device. The format like:
|
|
{dev_name, playback, sample_rates[4], channels, format[4], period_time, periods}.
|
|
|
|
- dev_name (string): pcm2c or pcm2p or others.
|
|
- playback (bool): true or false.
|
|
- sample_rates(uint32 array): {16000, 32000}.
|
|
- channels (uint8, {min_chan, max_chan}): {1, 2}.
|
|
- format(uint8 array): {8,16,32}.
|
|
- period_time(uint32): 100, unit ms.
|
|
- periods (uint32): 4, buffer cnt.
|
|
e.g:
|
|
{"pcm2c", false, {8000, 16000, 44100}, {1, 2}, {16}, 100, 4},
|
|
{"pcm2p", true, {8000, 16000, 44100}, {1, 2}, {16}, 100, 4},

This dir is used to store the audio file for virtual capture or playback device.
|
|
The filename for capture device should comply with the format "devname_samplerate_channels_format.pcm".
|
|
e.g: pcm2c_16000_2_16.pcm.
|
|
The filename format of playback device is the same as capture device.
|
|
e.g: pcm2p_16000_2_16.pcm.
