From e92935e13a052df7e6bc274e00fc91b80531f1e4 Mon Sep 17 00:00:00 2001 From: Roland Stigge Date: Fri, 18 May 2012 10:19:52 +0200 Subject: gpio/lpc32xx: Add device tree support This patch adds device tree support for gpio-lpc32xx.c. To register the various GPIO banks as (struct) gpio_chips via the same DT gpio-controller, we utilize the adjusted of_xlate API to manipulate the actually used struct gpio_chip.
