Subject: ARM: ux500: move old HREF ipgpio to the device tree
X-Git-Tag: upstream/snapshot3+hdmi~3514^2~6^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3ae2750a8c7112b83697dda5ef915886cb2a38cf;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ARM: ux500: move old HREF ipgpio to the device tree

The old HREFs (MOP500) were controlling an image-processor
GPIO (IPGPIO) by using hogs. Do the same thing with device tree
and get rid of the mop500_pins setting.
