Subject: [PATCH 3/5] dt-bindings: PCI: snps,dw-pcie: Add msi-parent for msi handle check
Date: Sat,  2 May 2026 18:13:16 +0800	[thread overview]
Message-ID: <20260502101319.2364052-4-inochiama@gmail.com> (raw)
In-Reply-To: <20260502101319.2364052-1-inochiama@gmail.com>

The IMSIC device on RISC-V based system does not require ID
remapping for MSI. So this device only needs "msi-parent"
property for IMSIC-based SoC, and the "msi-map" is not a
necessary property.

Add new condition for msi handling on IMSIC based SoC.
