From 9798e47ff232c48b3c25b9a6b9395b505e389475 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 12 Feb 2013 17:24:04 -0700 Subject: [PATCH] ARM: tegra: create a DT header defining GPIO IDs All Tegra GPIOs are named after the GPIO bank and GPIO number within the bank. Define a macro to calculate the GPIO ID based on those parameters. Make the macro available via all Tegra .dtsip files.
