Subject: [RFC PATCH v3 16/17] ACPI: RISC-V: Create PLIC platform device
Date: Tue, 19 Dec 2023 23:15:25 +0530 [thread overview]
Message-ID: <20231219174526.2235150-17-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20231219174526.2235150-1-sunilvl@ventanamicro.com>
Since PLIC needs to be a platform device, probe the MADT and create
platform devices for each PLIC in the system.
