dt-bindings: More dropping redundant minItems/maxItems

2021-07-15T14:45:27+00:00

Another round of removing redundant minItems/maxItems from new schema in
the recent merge window.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

dt-binding: memory: pl353-smc: Fix the NAND controller node in the example

2021-06-10T15:14:36+00:00

To be fully valid, the NAND controller node in the example should be
named nand-controller instead of flash, should be at the address @0,0
instead of @e1000000 and should have a couple of:
- #address-cells
- #size-cells
properties.

The label is being renamed nfc0 as well which is more usual than nand_0.

dt-binding: memory: pl353-smc: Drop unsupported nodes from the example

2021-06-10T15:14:36+00:00

These nodes are given as examples and are not described nor used
anywhere else. There is also no hardware of my knowledge compatible with
these yet. If we want to be backward compatible, then we should avoid
partially describing nodes and their content while there are no users.
Plus, the examples are wrong (the addresses should be updated) so
let's drop them before converting this file to yaml (only the NAND node,
which will be fixed in the example and described somewhere else is
kept).
