[PATCH 6.6 123/156] dt-bindings: nvmem: mxs-ocotp: Document fsl,ocotp

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Fabio Estevam <festevam@xxxxxxx>

commit a2a8aefecbd0f87d6127951cef33b3def8439057 upstream.

Both imx23.dtsi and imx28.dtsi describe the OCOTP nodes in
the format:

compatible = "fsl,imx28-ocotp", "fsl,ocotp";

Document the "fsl,ocotp" entry to fix the following schema
warning:

efuse@8002c000: compatible: ['fsl,imx23-ocotp', 'fsl,ocotp'] is too long
from schema $id: http://devicetree.org/schemas/nvmem/mxs-ocotp.yaml#
