From ffee19091a4e0c5dae0e83a6e0927c0f5c554537 Mon Sep 17 00:00:00 2001 From: Gyungoh Yoo Date: Thu, 9 Aug 2012 14:24:34 -0600 Subject: regulator: add MAX8907 driver The MAX8907 is an I2C-based power-management IC containing voltage regulators, a reset controller, a real-time clock, and a touch-screen controller. The original driver was written by: * Gyungoh Yoo Various fixes and enhancements by: * Jin Park * Tom Cherry * Prashant Gaikwad * Dan Willemsen * Laxman Dewangan During upstreaming, I (swarren): * Converted to regmap. * Allowed probing from device tree. * Reworked the regulator driver to be represented as a single device that provides multiple regulators, rather than as a device per regulator. * Replaced many regulator ops with standard functions. * Added ability to specify supplies for each regulator. * Removed the WLED regulator. If/when we expose this in the driver, it should be a backlight object not a regulator object. * Renamed from max8907c->max8907, since the driver covers at least the C and B revisions. * General cleanup.
