From 0ba69e089827c24f5a4b21124185914f9de4f466 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 16 Jul 2015 21:08:23 +0200 Subject: gpio: mpc8xxx: add support for MPC5125 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The gpio controller on MPC5125 is identical to the MPC5121 register wise, the only difference is that the lines 0..3 are input only instead of 28..31 on MPC5121.
