[PATCH v3 0/3] mtd: rawnand: omap_elm: convert DT binding to yaml

[Roger Quadros]

Hi,

This series converts omap_elm DT bindings to yaml and adds
support for ELM on AM64 SoC.

Changelog:
v3
- use 'enum' for compatible specifier. Get rid of 'items'.

v2
- explain hwmod usage deprecated in commit log
- fix example node name to 'ecc'
- remove 'items' for single compatible specifier

cheers,
-roger

[PATCH v3 1/3] dt-bindings: mtd: ti,elm: Convert to yaml

[Roger Quadros]

Convert elm.txt to ti,elm.yaml.

hwmod framework use is deprecated for new platforms
so mark it so.
