Subject: gpio/ixp4xx: Register the base PA instead of its VA in fwnode
X-Git-Tag: v5.4-rc1~194^2~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ac1213b7d79580ca52d7517e61e1ec4120134f0c;p=platform%2Fkernel%2Flinux-rpi.git

gpio/ixp4xx: Register the base PA instead of its VA in fwnode

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