Subject: [PATCH 1264/1350] ASoC: add HiFiBerry ADC8x 8-channel ADC to
|
||
|
|
simple-card-driver
|
||
|
|
|
||
|
|
Definitions for the 8 channel ADC card. The card uses only
|
||
|
|
HW-controlled devices which allows the uses of the 'dummy-dai'.
|
||
|
|
It will run only on a PI5 as it requires the designware I2S0 module.
|
||
|
|
|
||
|
|
The necessary output lanes I2S0_DI[0..3] are claimed from within the
|
||
|
|
DT overlay.
