      add single-wire serial bus interface (SSBI) driver · e44b0cee
      Kenneth Heitke authored
      SSBI is the Qualcomm single-wire serial bus interface used to connect
      the MSM devices to the PMIC and other devices.
      
      Since SSBI only supports a single slave, the driver gets the name of the
      slave device passed in from the board file through the master device's
      platform data.
      
      SSBI registers pretty early (postcore), so that the PMIC can come up
      before the board init. This is useful if the board init requires the
      use of gpios that are connected through the PMIC.
      
      Based on a patch by Dima Zavin <dima@android.com> that can be found at:
      http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=eb060bac4
      
      This patch adds PMIC Arbiter support for the MSM8660. The PMIC Arbiter
      is a hardware wrapper around the SSBI 2.0 controller that is designed to
      overcome concurrency issues and security limitations.  A controller_type
      field is added to the platform data to specify the type of the SSBI
      controller (1.0, 2.0, or PMIC Arbiter).
      
      [davidb@codeaurora.org:
       I've moved this driver into drivers/ssbi/ and added an include for
       linux/module.h so that it will compile]
