Subject: [PATCH 0915/1085] ASOc: Add HiFiBerry DAC8X to the simple card driver
|
|
|
|
Defines the settings for the 8 channel version of the standard
|
|
DAC by overwriting the number of channels in the DAI defs.
|
|
It can run in 8ch mode only on PI5 using the 4 lane data output
|
|
of the designware I2S0 module.
