pinctrl: dt-bindings: samsung: Add header with values used for configuration Hard-coded pinctrl configuration values are scattered through DTS files. The numbers are difficult to decode by human, especially without the datasheet. Additionally the drive strength differs between S3C64xx, S5PV210 and Exynos SoC families increasing the confusion. The header will help making this more readable and maintainable.

pinctrl: dt-bindings: samsung: add drive strength macros for Exynos5433 Commit 5db7e3bb87df ("pinctrl: dt-bindings: samsung: Add header with values used for configuration") has added a header file for defining the pinctrl values in order to avoid hardcoded settings in the Exynos DTS related files. Extend samsung.h to the Exynos5433 for drive strength values which are strictly related to the particular SoC and may defer from others.

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.
