From: Krzysztof Kozlowski <krzk@kernel.org> commit bd7e7ff56feea7810df900fb09c9741d259861d9 upstream. On Odroid XU LDO12 and LDO15 supplies the power to USB 3.0 blocks but the GPK GPIO pins are supplied by LDO7 (VDDQ_LCD). LDO7 also supplies GPJ GPIO pins. The Exynos pinctrl driver does not take any supplies, so to have entire GPIO block always available, make the regulator always on.
