    regulator: add MAX8907 driver · ffee1909
    Gyungoh Yoo 提交于
    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 <jack.yoo@maxim-ic.com>
    
    Various fixes and enhancements by:
    * Jin Park <jinyoungp@nvidia.com>
    * Tom Cherry <tcherry@nvidia.com>
    * Prashant Gaikwad <pgaikwad@nvidia.com>
    * Dan Willemsen <dwillemsen@nvidia.com>
    * Laxman Dewangan <ldewangan@nvidia.com>
    
    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.
