[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The `#address-cells` and `#size-cells` properties were left behind in the `qspi1_flash: flash@0` node after moving its partition children into a `partitions` subnode.

--- Patch [5]: [PATCH v7 5/7] ARM: dts: microchip: sama5d27_wlsom1: use fixed-partitions for QSPI flash ---
commit 2272ae3c8afd10d0823376b2412b60934678478f
Author: Manikandan Muralidharan <manikandan.m@microchip.com>
Subject: ARM: dts: microchip: sama5d27_wlsom1: use fixed-partitions for QSPI flash

This commit moves the QSPI flash partitions into a new partitions
subnode with the fixed-partitions compatible string. This change
aligns the device tree with the current MTD partition binding requirements.

[Severity: Low]
This is a pre-existing issue, but should the #address-cells and
#size-cells properties be removed from the qspi1_flash: flash@0 node?

Now that the partitions have been moved to the new partitions subnode,
leaving these properties in the parent flash node can cause dtc warnings
(avoid_unnecessary_addr_size).

It also violates the MTD binding schema, which deprecates them at the
flash node level when a partitions subnode is used.
