From 2891ba2906b6d2fd453042f410a11e6fc3edc37d Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Mon, 27 Oct 2014 10:21:18 +0900 Subject: [PATCH] pinctrl: exynos: Add support for Exynos4415 The pin controllers of Exynos4415 are similar to Exynos4412, but certain differences cause the need to create separate driver data for it. This patch adds pin controller and bank descriptor arrays to the driver to support the new SoC.
