Subject: [PATCH v12 15/21] PCI: microchip: Add event IRQ domain ops to struct plda_event
Date: Wed, 6 Dec 2023 18:58:33 +0800 [thread overview]
Message-ID: <20231206105839.25805-16-minda.chen@starfivetech.com> (raw)
In-Reply-To: <20231206105839.25805-1-minda.chen@starfivetech.com>
For lack of an MSI controller, The new added PCIe interrupts have to be
added to global interrupt event field. PolarFire event domain ops can not
be re-used.
PLDA event domain ops instances will be implemented in later patch.
