From c8587eeef8fc219e806e868c6f0c7170c769efab Mon Sep 17 00:00:00 2001 From: Christian Ruppert Date: Thu, 13 Jun 2013 14:55:31 +0200 Subject: pinctrl: add pin list based GPIO ranges Traditionally, GPIO ranges are based on consecutive ranges of both GPIO and pin numbers. This patch allows for GPIO ranges with arbitrary lists of pin numbers.
