Subject: [PATCH 1283/1295] Overlays: Add definitions for HiFiBerry 8 channel
|
|
DAC8X
|
|
|
|
Dedicated overlay claiming all 4 data lanes of the designware
|
|
I2S0 module to drive 4x PCM5102. THe devices share BCLK and
|
|
LRCLK, therefore all outputs will always run at the same
|
|
samplerate and format.
|
|
|
|
Compatible only with PI5!
