From 03f0e4c7cd316a4b0b68776e39865ccf60a883a6 Mon Sep 17 00:00:00 2001 From: Adrian Alonso Date: Tue, 11 Aug 2015 11:19:50 -0500 Subject: imx: iomux-v3: add imx7d support for iomuxc * Add imx7d support for iomux controller * imx7d has two iomux controllers iomuxc (0x3033000) and iomuxc-lpsr (0x302C0000) each conroller provides control and mux mode pad registers but shares iomuxc input select register with iomuxc-lpsr IOMUX_CONFIG_LPSR flag is used to properly set daisy chain settings for iomuxc-lpsr pads. * Since mx7d introduces LPSR IOMUX pins, add new base to IOMUX v3 driver for these LPSR pins.
