This is the NVIDIA technique for managing the peak current consumption of the power rail. EDP management manages the components to avoid exceeding the design limits, it limits peak current consumption while maximizing performance. if EDP_MANAGEMENT config TEGRA_CPU_EDP_LIMITS bool "VDD_CPU EDP" depends on ARCH_TEGRA depends on CPU_FREQ && THERMAL default n help Enforce electrical design limits on CPU rail. VDD_CPU EDP prevents the CPU from drawing more current than its voltage regulator can supply.
