Subject: [PATCH 1290/1295] Overlays:Add specific clk-producer/-consumer
|
|
overlays for Hifiberry DAC+
|
|
|
|
As the easy switching of the I2S module bewteen clock producer/consumer
|
|
on the PI5 is not possible, two specific DT-overlays are introduced.
|
|
The DAC+PRO boards with onboard clocks use the -PRO overlay, the boards
|
|
without oscillators the -STD version.
|
|
The "hifiberry-dacplus,slave" parameter in the -STD overlay disables
|
|
the automatic clock detection inside the hifiberry-dacplus driver.
|
|
|
|
The former hifiberry-dacplus overlay is kept for compatibility but
|
|
will be deprecated.
