[PATCH v2] spi: dt-bindings: cdns,qspi-nor: Update minItems/maxItems of resets for Cadence OSPI controller
Posted by Amit Kumar Mahapatra 6 months, 3 weeks ago
The Cadence Octal SPI (OSPI) controller on AMD Versal SoCs requires only
one reset entry. To reflect this, the maxItems for "resets" and
"reset-names" has been set to 1 for AMD Versal SoCs, and the minItems for
these properties has also been updated to 1.

BRANCH: mtd/next

Changes in v2:
 - Removed "resets" & "reset-names" from required properties.
 - To address review comments, removed "maxItems" from "reset-names".

I think you're still missing one of the things Krzysztof requested on
v1, cos you reduce minItems for all platforms without restricting
it back to 2 for non-versal platforms.
