Subject: [PATCH 1/3] lib: sbi_irqchip: Add irqchip private context pointer in sbi_irqchip_device
Date: Wed, 11 Feb 2026 17:20:23 -0500 [thread overview]
Message-ID: <20260211222025.2463312-2-raymondmaoca@gmail.com> (raw)
In-Reply-To: <20260211222025.2463312-1-raymondmaoca@gmail.com>
From: Raymond Mao <raymond.mao@riscstar.com>
HW specific private data is required for irqchip device operations,
for example, for APLIC, address, num_idc and num_source are needed
for mask / unmask / claim an IRQ, thus it is reasonable to add a
private HW data pointer in sbi_irqchip_device.
