Subject: [PATCH 1293/1295] overlays: Sets i2s_clk_producer as default for
|
|
Hifiberry DACplusADC
|
|
|
|
As we have never released a (standard) DACplusADC board with onboard
|
|
clocks, we can simply use a fixed setup avoiding incompatibilities
|
|
with Pi5 during driver init. Setting 'hifiberry-dacplusadc,slave' in
|
|
the overlays disables the failing clock probing mechanism.
|
|
|
|
Removes 'slave' parameter description from README which is still
|
|
supported but not needed.
