Pankaj Dubey 860ac88abe pinctrl: dt-bindings: samsung: Add Exynos7 specific pinctrl macro definitions
Exynos7 SoC pinctrl configurations are similar to existing Exynos4/5 except
for FSYS1 pinctrl drive strengths. So adding Exynos7 specific FSYS1 blocks
pinctrl driver strength related macros which will be used in Exynos7
DTSi files.
