From 07e1c0ae83faff57477392be87734128db5e1b14 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Thu, 11 Aug 2016 14:02:51 +0800 Subject: imx: iomux: fix snvs usage for i.MX6ULL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SNVS TAMPER pin and BOOT MODE pins are in SNVS IOMUXC module, not in IOMUXC, so correct the related registers' offset. Use IOMUX_CONFIG_LPSR flag for these pins, so we can differentiate them from iomuxc pins.
