Subject: [PATCH] dt-bindings: firmware: xilinx: Describe soc-vvmem subnode
Describe soc-nvmem subnode as the part of firmware node. The name can't be
pure nvmem because dt-schema already defines it as array property that's
why different name should be used.
Signed-off-by: Michal Simek <michal.simek@....com>

Dt binding for nvmem node has been already merged and it is the part of
linux-next tree.
Here is the reference to it just in case:
