Subject: ARM: ux500: Do not register the PMU device if booting with ATAGs
X-Git-Tag: v3.13-rc1~156^2~11^2~37
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a6fdf37e2a8fd16873d9772ba10f7ab8737aca4f;p=kernel%2Fkernel-generic.git

ARM: ux500: Do not register the PMU device if booting with ATAGs

It's time to remove all ATAG support from ux500 and rely solely on
Device Tree booting. This patch is part of that endeavour.
