Tegra124 CPU frequency scaling driver bindings ---------------------------------------------- Both required and optional properties listed below must be defined under node /cpus/cpu@0. Required properties: - clocks: Must contain an entry for each entry in clock-names. See ../clocks/clock-bindings.txt for details. - clock-names: Must include the following entries: - cpu_g: Clock mux for the fast CPU cluster. - pll_x: Fast PLL clocksource. - pll_p: Auxiliary PLL used during fast PLL rate changes. - dfll: Fast DFLL clocksource that also automatically scales CPU voltage. Optional properties: - clock-latency: Specify the possible maximum transition latency for clock, in unit of nanoseconds. Example: -------- cpus { #address-cells = <1>; #size-cells = <0>; cpu@0 { device_type = "cpu"; compatible = "arm,cortex-a15"; reg = <0>; clocks = <&tegra_car TEGRA124_CLK_CCLK_G>, <&tegra_car TEGRA124_CLK_PLL_X>, <&tegra_car TEGRA124_CLK_PLL_P>, <&dfll>; clock-names = "cpu_g", "pll_x", "pll_p", "dfll"; clock-latency = <300000>; }; <...> }; |
