From 05cc995f4d44c2b14a1f15f3271cc9715cb81099 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Wed, 3 Aug 2016 14:05:57 +0200 Subject: gpio: mmio: add brcm,bcm6345 support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds support for the GPIO found in Broadcom's bcm63xx-gpio chips. This GPIO controller is used in the following Broadcom SoCs: BCM6338, BCM6345. It can be used in newer SoCs, without the capability of pin multiplexing.
