Subject: [PATCH v9 15/20] PCI: microchip: Add event IRQ domain ops to struct plda_event
Date: Fri, 20 Oct 2023 18:43:36 +0800 [thread overview]
Message-ID: <20231020104341.63157-16-minda.chen@starfivetech.com> (raw)
In-Reply-To: <20231020104341.63157-1-minda.chen@starfivetech.com>
For PLDA lack of an MSI controller, The new added
PCIe interrupts can not be added to MSI.PolarFire event
domain ops can not be re-used.
PLDA event domain ops instances will be implemented
in later patch.
