Subject: [PATCH v9 13/20] PCI: microchip: Add INTx and MSI event num to struct plda_event
Date: Fri, 20 Oct 2023 18:43:34 +0800 [thread overview]
Message-ID: <20231020104341.63157-14-minda.chen@starfivetech.com> (raw)
In-Reply-To: <20231020104341.63157-1-minda.chen@starfivetech.com>
The INTx and MSI interrupt event num is different in Microchip and
StarFive platform.
