+OMAP Counter-32K bindings
+
+Required properties:
+- compatible: Must be "ti,omap-counter32k" for OMAP controllers
+- reg: Contains timer register address range (base address and length)
+- ti,hwmods: Name of the hwmod associated to the counter, which is typically
+ "counter_32k"
+
+Example:
+
+counter32k: counter@4a304000 {
+ compatible = "ti,omap-counter32k";
+ reg = <0x4a304000 0x20>;
+ ti,hwmods = "counter_32k";

+OMAP Timer bindings
+
+Required properties:
+- compatible: Must be "ti,omap2-timer" for OMAP2+ controllers.
+- reg: Contains timer register address range (base address and
+ length).
+- interrupts: Contains the interrupt information for the timer. The
+ format is being dependent on which interrupt controller
+ the OMAP device uses.
+- ti,hwmods: Name of the hwmod associated to the timer, "timer<X>",
+ where <X> is the instance number of the timer from the
+ HW spec.
+
+Optional properties:
+- ti,timer-alwon: Indicates the timer is in an alway-on power domain.
+- ti,timer-dsp: Indicates the timer can interrupt the on-chip DSP in
+ addition to the ARM CPU.
+- ti,timer-pwm: Indicates the timer can generate a PWM output.
+- ti,timer-secure: Indicates the timer is reserved on a secure OMAP device
+ and therefore cannot be used by the kernel.
+
+Example:
+
+timer12: timer@48304000 {
+ compatible = "ti,omap2-timer";
+ reg = <0x48304000 0x400>;
+ interrupts = <95>;
+ ti,hwmods = "timer12"
+ ti,timer-alwon;
+ ti,timer-secure;
+};
properties:
- compatible : Should be "ti,omap-ocp2scp"
+- reg : Address and length of the register set for the device
- #address-cells, #size-cells : Must be present if the device has sub-nodes
- ranges : the child address space are mapped 1:1 onto the parent address space
- ti,hwmods : must be "ocp2scp_usb_phy"
Sub-nodes:
All the devices connected to ocp2scp are described using sub-node to ocp2scp
+
+ocp2scp@4a0ad000 {
+ compatible = "ti,omap-ocp2scp";
+ reg = <0x4a0ad000 0x1f>;

- multipoint : Should be "1" indicating the musb controller supports
multipoint. This is a MUSB configuration-specific setting.
