+* 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.
