can we specify memory-region and memory-region-names properties like the code
below?
memory-region:
items:
- description:
Phandle for the node (wo-emi) used to run firmware EMI region
- description:
Phandle for the node (wo-ilm) used to run firmware ILM region
- description:
Phandle for the node (wo-data) used to run firmware CPU DATA region
memory-region-names:
items:
- const: wo-emi
- const: wo-ilm
- const: wo-data

Lorenzo
