From 5c13941acc513669c7d07b28789c3f9ba66ddddf Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 11 Mar 2009 03:30:43 -0800 Subject: MMC: regulator utilities Glue between MMC and regulator stacks ... verified with some OMAP3 boards using adjustable and configured-as-fixed regulators on several MMC controllers. These calls are intended to be used by MMC host adapters using at least one regulator per host. Examples include slots with regulators supporting multiple voltages and ones using multiple voltage rails (e.g. DAT4..DAT7 using a separate supply, or a split rail chip like certain SDIO WLAN or eMMC solutions).
