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.
