Subject: [PATCH v2] spi: dt-bindings: cdns,qspi-nor: Update minItems/maxItems of resets for Cadence OSPI controller
Date: Thu, 22 May 2025 16:17:45 +0530 [thread overview]
Message-ID: <20250522104745.327675-1-amit.kumar-mahapatra@amd.com> (raw)
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.
Signed-off-by: Amit Kumar Mahapatra <amit.kumar-mahapatra@amd.com>

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