Subject: [PATCH v2 4/7] pinctrl: samsung: Add GPF support for Exynos5433

From: Joonyoung Shim <jy0922.shim@...sung.com>

This patch add the support of GPF[1-5] pin of Exynos5433 SoC. The GPFx need
to support the multiple memory map because the registers of GPFx are located
in the different domain.
