Subject: [RFC PATCH 2/6] irqchip: mips-cpu: Allocate fwnode for non-DT platforms
Date: Thu, 26 Mar 2020 14:16:59 +0800
Message-ID: <20200326061704.387483-4-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20200326061704.387483-1-jiaxun.yang@flygoat.com>

fwnode is required by fwspec based domain opreations to match domains.
