From 880cf0717f70678b2ecd6bb762e469c64c3b0d83 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Wed, 19 Jun 2013 01:22:20 +0900 Subject: [PATCH] ARM: SAMSUNG: Introduce GPIO_SAMSUNG Kconfig entry This patch adds Kconfig entry that selects whether legacy Samsung GPIO driver should be built or not. For platforms that support only DT based boot, the new pinctrl driver is used and so the old one is not needed.
