-Generic CPU0 cpufreq driver
-
-It is a generic cpufreq driver for CPU0 frequency management. It
-supports both uniprocessor (UP) and symmetric multiprocessor (SMP)
-systems which share clock and voltage across all CPUs.
-
-Both required and optional properties listed below must be defined
-under node /cpus/cpu@0.
-
-Required properties:
-- operating-points: Refer to Documentation/devicetree/bindings/power/opp.txt
- for details
-
-Optional properties:
-- clock-latency: Specify the possible maximum transition latency for clock,
- in unit of nanoseconds.
-- voltage-tolerance: Specify the CPU voltage tolerance in percentage.
-
-Examples:
-
-cpus {
- #address-cells = <1>;
- #size-cells = <0>;
-
- cpu@0 {
- compatible = "arm,cortex-a9";
- reg = <0>;
- next-level-cache = <&L2>;
- operating-points = <
- /* kHz uV */
- 792000 1100000
- 396000 950000
- 198000 850000
- >;
- clock-latency = <61036>; /* two CLK32 periods */
- };
-
- cpu@1 {
- compatible = "arm,cortex-a9";
- reg = <1>;
- next-level-cache = <&L2>;
- };
-
- cpu@2 {
- compatible = "arm,cortex-a9";
- reg = <2>;
- next-level-cache = <&L2>;
- };
-
- cpu@3 {
- compatible = "arm,cortex-a9";
- reg = <3>;
- next-level-cache = <&L2>;
