Subject: [PATCH v15 01/10] irqchip/riscv-intc: Fix low-level interrupt handler setup for AIA
Date: Mon, 26 Feb 2024 09:37:37 +0530
Message-Id: <20240226040746.1396416-2-apatel@ventanamicro.com>
In-Reply-To: <20240226040746.1396416-1-apatel@ventanamicro.com>

Use riscv_intc_aia_irq() as the low-level interrupt handler and print
"using AIA" in the INTC boot banner when AIA is available.

Fixes: c1be2ae5987a ("irqchip/riscv-intc: Add support for RISC-V AIA")
