[PATCH 4/8] irqchip/gic-v2m: Register the frame's PA instead of its VA in fwnode

From: Marc Zyngier
Date: Tue Aug 06 2019 - 10:57:39 EST


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