Subject: [ARM] 4429/2: iop13xx: expose the 'iop' attribute versions of the tpmi control registers
X-Git-Tag: v2.6.23-rc1~1101^2^4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=51198ea9478b6e10759ab07cd0b9917663c8df7a;p=platform%2Fkernel%2Flinux-3.10.git

[ARM] 4429/2: iop13xx: expose the 'iop' attribute versions of the tpmi control registers

The tpmi control registers can be accessed on the internal bus via an
address with PCI attributes or IOP attributes (i.e. read-only,
read-write... etc).  The sas driver needs access to the iop-attribute
registers for initialization.

Changelog:
* use ARRAY_SIZE for num_resources, Russell King
