Subject: [PATCH] BCM270X_DT: Sound DT adjustments for Dynamic DT
|
2016-06-08 09:59:37 +00:00
|
|
|
|
|
|
|
There are a number of issues when loading and unloading overlays for
|
|
|
|
sound cards:
|
|
|
|
1) The "sound" and "audio" nodes must be children of a bus node, such
|
|
|
|
as "/soc", otherwise the DT changes don't result in platform devices
|
|
|
|
being created and deleted.
|
|
|
|
2) The "/sound" node must have a "disabled" status property, otherwise
|
|
|
|
setting the status to "okay" won't be detected.
|
|
|
|
3) ALSA doesn't like having components unloaded under its feet, and it
|
|
|
|
is easy to deadlock or crash. Ordering the overlay fragments so that
|
|
|
|
the sound card appears last avoids this problem.
