|  | Exynos5440 cpufreq driver | 
|  | ------------------- | 
|  |  | 
|  | Exynos5440 SoC cpufreq driver for CPU frequency scaling. | 
|  |  | 
|  | Required properties: | 
|  | - interrupts: Interrupt to know the completion of cpu frequency change. | 
|  | - operating-points: Table of frequencies and voltage CPU could be transitioned into, | 
|  | in the decreasing order. Frequency should be in KHz units and voltage | 
|  | should be in microvolts. | 
|  |  | 
|  | Optional properties: | 
|  | - clock-latency: Clock monitor latency in microsecond. | 
|  |  | 
|  | All the required listed above must be defined under node cpufreq. | 
|  |  | 
|  | Example: | 
|  | -------- | 
|  | cpufreq@160000 { | 
|  | compatible = "samsung,exynos5440-cpufreq"; | 
|  | reg = <0x160000 0x1000>; | 
|  | interrupts = <0 57 0>; | 
|  | operating-points = < | 
|  | 1000000 975000 | 
|  | 800000  925000>; | 
|  | clock-latency = <100000>; | 
|  | }; |
