* Qualcomm SSBI



Some Qualcomm MSM devices contain a point-to-point serial bus used to

communicate with a limited range of devices (mostly power management

chips).



These require the following properties:



- compatible: "qcom,ssbi"



- qcom,controller-type

  indicates the SSBI bus variant the controller should use to talk

  with the slave device.  This should be one of "ssbi", "ssbi2", or

  "pmic-arbiter".  The type chosen is determined by the attached

  slave.



The slave device should be the single child node of the ssbi device

with a compatible field.
