Subject: [PATCH] ARM: dts: Move audio node under the vchiq parent
|
|
|
|
VCHIQ kernel clients are now instantiated as platform drivers rather
|
|
than using DT, but the children of the vchiq device can optionally be
|
|
given a sub-node of the vchiq parent for configuration and to disable
|
|
them.
|
|
|
|
Move the existing audio node beneath the vchiq parent, to prevent
|
|
multiple instantiation and unpleasant warnings. Note that the node
|
|
name has to match the module name - "bcm2835_audio".
