* Name: esp32s2_es8311_initialize
|
|
*
|
|
* Description:
|
|
* This function is called by platform-specific, setup logic to configure
|
|
* and register the ES8311 device. This function will register the driver
|
|
* as /dev/audio/pcm[x] where x is determined by the I2S port number.
|
|
*
|
|
* Input Parameters:
|
|
* i2c_port - The I2C port used for the device;
|
|
* i2c_addr - The I2C address used by the device;
|
|
* i2c_freq - The I2C frequency used for the device.
|
|
*
|
|
* Returned Value:
|
|
* Zero is returned on success. Otherwise, a negated errno value is
|
|
* returned to indicate the nature of the failure.
|
|
