-Texas Instruments SmartReflex binding
-
-SmartReflex is used to set and adjust the SoC operating points.
-
-
-Required properties:
-
-compatible: Shall be one of the following:
- "ti,omap3-smartreflex-core"
- "ti,omap3-smartreflex-mpu-iva"
- "ti,omap4-smartreflex-core"
- "ti,omap4-smartreflex-mpu"
- "ti,omap4-smartreflex-iva"
-
-reg: Shall contain the device instance IO range
-
-interrupts: Shall contain the device instance interrupt
-
-
-Optional properties:
-
-ti,hwmods: Shall contain the TI interconnect module name if needed
- by the SoC
-
-
-Example:
-
- smartreflex_iva: smartreflex@4a0db000 {
- compatible = "ti,omap4-smartreflex-iva";
- reg = <0x4a0db000 0x80>;

IIRC, ti,hwmods has been removed on omap4.
