Subject: [PULL 27/40] hw/riscv: virt: Use AIA INTC compatible string when available
Date: Sat, 12 Feb 2022 10:00:18 +1000 [thread overview]
Message-ID: <20220212000031.3946524-28-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20220212000031.3946524-1-alistair.francis@opensource.wdc.com>
From: Anup Patel <anup.patel@wdc.com>
We should use the AIA INTC compatible string in the CPU INTC
DT nodes when the CPUs support AIA feature. This will allow
Linux INTC driver to use AIA local interrupt CSRs.
