The schema for 'sercomm,scpart-id' is broken. The 'if' condition is never true because 'compatible' is in the parent node, not the child node the sub-schema applies to. The example passes as there are no constraints on additional/unevaluated properties. That's a secondary issue which is complicated due to nested partitions. Drop the if/then schema and the unnecessary 'allOf' so that the 'sercomm,scpart-id' property is at least defined.

title: Fixed partitions
|
|
|
|
description: |
|
|
This binding can be used on platforms which have strong conventions about
|
|
which portions of a flash are used for what purposes, but which don't use an
|
|
on-flash partition table such as RedBoot.
|
|
|
|
The partition table should be a node named "partitions". Partitions are then
|
|
defined as subnodes.

description: Partition id in Sercomm partition map. Mtd parser

|
uses this id to find a record in the partition map containing
|
|
offset and size of the current partition. The values from
|
|
partition map overrides partition offset and size defined in
|
|
reg property of the dts. Frequently these values are the same,
|
|
but may differ if device has bad eraseblocks on a flash.
