Subject: [PATCH 3/8] irqchip/gic: Register the distributor's PA instead of its VA in fwnode
Date: Tue, 6 Aug 2019 15:57:11 +0100 [thread overview]
Message-ID: <20190806145716.125421-4-maz@kernel.org> (raw)
In-Reply-To: <20190806145716.125421-1-maz@kernel.org>
Do not expose the distributor's VA (it appears in debugfs). Instead,
record the PA, which at least can be used to precisely identify
the associated irqchip and domain.
