Subject: [PATCH v6 14/19] PCI: microchip: Add event IRQ domain ops to plda_event struct
Date: Fri, 15 Sep 2023 18:22:38 +0800	[thread overview]
Message-ID: <20230915102243.59775-15-minda.chen@starfivetech.com> (raw)
In-Reply-To: <20230915102243.59775-1-minda.chen@starfivetech.com>

For register different event domain ops, Add domain_ops
pointer to plda_event struct.
