Subject: [PATCH 2/8] irqchip/gic-v3-its: Register the ITS' PA instead of its VA in fwnode
Date: Tue,  6 Aug 2019 15:57:10 +0100	[thread overview]
Message-ID: <20190806145716.125421-3-maz@kernel.org> (raw)
In-Reply-To: <20190806145716.125421-1-maz@kernel.org>

Do not expose the ITS' VA (it appears in debugfs). Instead, record
the PA, which at least can be used to precisely identify the associated
irqchip and domain.
