From: Russell King Date: Sat, 5 Nov 2011 11:26:32 +0000 (+0000) Subject: ARM: restart: iop3xx: use new restart hook X-Git-Tag: upstream/snapshot3+hdmi~8412^2^2~39 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bec92b1ec67b4998b6a3bad7c2f03c846cbac71e;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git ARM: restart: iop3xx: use new restart hook Hook these platforms restart code into the arm_pm_restart hook rather than using arch_reset(). In doing so, we split out the n2100 platform specific restart handler into the n2100 platform file.
