Subject: [PATCH] dtoverlays: adds support for Hifiberry ADC8x to the DAC8x
|
|
|
|
Allows the usage of ADC8x stacked on top of the DAC8x.
|
|
Activates all I2S pins and uses now the dummy-dai instead
|
|
of the formerly used pcm5102 to allow the use of a
|
|
capture device, too. The simple card driver will
|
|
probe for the ADC8x and may activate the 8 channel
|
|
capture. Uses GPIO5 for detection.

Info: Configures the HifiBerry DAC8X audio cards (only on Pi5)
|
|
+ This driver also detects a stacked ADC8x and activates the

+ capture capabilities.
|
|
+ Note: for standalone use of the ADC8x activate the ADC8x module.
