- Subject: [PATCH 376/381] BCM270X_DT: Fix rpi-dac overlay
- 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.
- See: http://forum.kodi.tv/showthread.php?tid=269814&pid=2349776#pid2349776
