From 3d2613c4289ff22de3aa24d2d0a29e33937f023a Mon Sep 17 00:00:00 2001 From: Weike Chen Date: Wed, 17 Sep 2014 09:18:39 -0700 Subject: GPIO: gpio-dwapb: Enable platform driver binding to MFD driver The Synopsys DesignWare APB GPIO driver only supports open firmware devices. But, like Intel Quark X1000 SOC, which has a single PCI function exporting a GPIO and an I2C controller, it is a Multifunction device. This patch is to enable the current Synopsys DesignWare APB GPIO driver to support the Multifunction device which exports the designware GPIO controller.
