Subject: [PATCH v6 4/6] dt-bindings: PCI: snps,dw-pcie: Add msi-parent for MSI handle check
Date: Wed, 23 Sep 2026 09:50:13 +0800	[thread overview]
Message-ID: <20260923015016.64069-5-inochiama@gmail.com> (raw)
In-Reply-To: <20260923015016.64069-1-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.
