Subject: [PATCH 1263/1350] dtoverlays: adds the definitions for the HiFiBerry
|
|
8-channel ADC
|
|
|
|
Additions and changes for the 8 channel ADC card. This 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.
