From 31e37a183e79e4ba6b6640d65279fa1e8394d24a Mon Sep 17 00:00:00 2001 From: Peter De Schrijver Date: Wed, 14 Dec 2011 17:03:23 +0200 Subject: [PATCH] arm/tegra: add new fields to struct tegra_pingroup_desc Add new fields to struct tegra_pingroup_desc to support new hardware features introduced in the tegra30 SoC. The pinmux driver won't use those fields yet, but the tegra30 pinmux tables will already provide the necessary data.
