Subject: [PATCH v4 4/6] dt-bindings: PCI: snps,dw-pcie: Add msi-parent for MSI handle check
Date: Thu, 9 Jul 2026 12:00:24 +0800 [thread overview]
Message-ID: <20260709040027.958400-5-inochiama@gmail.com> (raw)
In-Reply-To: <20260709040027.958400-1-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.
