Users of common properties shouldn't have a type definition as the common schemas already have one. A few new ones slipped in and *-names was missed in the last clean-up pass. Drop all the unnecessary type references in the tree. A meta-schema update to catch these is pending.

fsl_rpmsg is a virtual audio device. Mapping to real hardware devices
|
|
are SAI, DMA controlled by Cortex M core. What we see from Linux
|
|
side is a device which provides audio service by rpmsg channel.

phandle to a node describing reserved memory (System RAM memory)
|

The M core can't access all the DDR memory space on some platform,
|
|
So reserved a specific memory for dma buffer which M core can
|
|
access.
