Subject: OMAP3+: VC: move on/onlp/ret/off command configuration into common init
X-Git-Tag: upstream/snapshot3+hdmi~8855^2^2~1^2~29
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=08d1c9a3e2dc7a285db7c689c42963d0f5271c1f;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

OMAP3+: VC: move on/onlp/ret/off command configuration into common init

Configuring the on/onlp/ret/off command values is common to OMAP3 & 4.
Move from OMAP3-only init into common VC init.
