[PATCH v3 5/9] pinctrl: mvebu: add pinctrl driver for Armada XP

Sebastian Hesselbarth sebastian.hesselbarth at gmail.com
Mon Sep 10 04:39:42 EDT 2012


From: Thomas Petazzoni <thomas.petazzoni at free-electrons.com>

This pinctrl driver is not a full-blown pinctrl driver from scratch:
it relies on the common pinctrl-mvebu driver, which is used for all
Marvell EBU SoCs.

v2: replaced variant with enum and used bitops.h

+* Marvell Armada XP SoC pinctrl driver for mpp
+
+Please refer to marvell,mvebu-pinctrl.txt in this directory for common binding
+part and usage.
+
+Required properties:
+- compatible: "marvell,mv78230-pinctrl", "marvell,mv78260-pinctrl",
+              "marvell,mv78460-pinctrl"
