Subject: [PATCH 383/423] BCM270X_DT: Fix rpi-dac overlay
|
2016-06-08 09:59:37 +00:00
|
|
|
|
|
|
|
|
The rpi-dac overlay is almost identical to the hifiberry-dac overlay -
|
|
|
|
|
the codec used is different but it also doesn't sit on the I2C bus. As
|
|
|
|
|
a result, when the overlays were modified for dynamic loading and it
|
|
|
|
|
was discovered that the hifiberry-dac overlay didn't work any more, the
|
|
|
|
|
the rpi-dac overlay was also broken.
|
|
|
|
|
|
|
|
|
|
The failure was caused by the fact that outside a bus, device names are
|
|
|
|
|
constructed from the concatenation of the path elements leading to it,
|
|
|
|
|
so moving the codec instantiation inside /soc caused the device name
|
|
|
|
|
to get a "soc" added, breaking ALSA's naming.
