+* 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.

+* MSM Timer
+
+Properties:
+
+- compatible : Should at least contain "qcom,msm-timer". More specific
+ properties specify which subsystem the timers are paired with.
+
+ "qcom,kpss-timer" - krait subsystem
+ "qcom,scss-timer" - scorpion subsystem
+
+- interrupts : Interrupts for the the debug timer, the first general purpose
+ timer, and optionally a second general purpose timer in that
+ order.
+
+- reg : Specifies the base address of the timer registers.
+
+- clock-frequency : The frequency of the debug timer and the general purpose
+ timer(s) in Hz in that order.
+
+Optional:
+
+- cpu-offset : per-cpu offset used when the timer is accessed without the
+ CPU remapping facilities. The offset is
+ cpu-offset + (0x10000 * cpu-nr).
+
+Example:
+
+ timer@200a000 {
+ compatible = "qcom,scss-timer", "qcom,msm-timer";
+ interrupts = <1 1 0x301>,
+ <1 2 0x301>,
+ <1 3 0x301>;
+ reg = <0x0200a000 0x100>;
+ clock-frequency = <19200000>,
+ <32768>;
+ cpu-offset = <0x40000>;
+ };
