Subject: [PATCH v4 5/7] ARM: dts: microchip: sama5d27_wlsom1: use fixed-partitions for QSPI flash
Date: Tue, 30 Jun 2026 14:54:04 +0530 [thread overview]
Message-ID: <20260630092406.150587-6-manikandan.m@microchip.com> (raw)
In-Reply-To: <20260630092406.150587-1-manikandan.m@microchip.com>
Move the QSPI flash partitions under a "partitions" node with the
"fixed-partitions" compatible, as required by the current MTD partition
binding, instead of declaring them as direct children of the flash node.
No functional change.
