General informations

The Linux kernel configuration item CONFIG_ARM_EXYNOS5_BUS_DEVFREQ has multiple definitions:

ARM Exynos5250 Bus DEVFREQ Driver found in drivers/devfreq/Kconfig

The configuration item CONFIG_ARM_EXYNOS5_BUS_DEVFREQ:

• prompt: ARM Exynos5250 Bus DEVFREQ Driver
• type: tristate
• depends on: CONFIG_SOC_EXYNOS5250
• defined in drivers/devfreq/Kconfig
• found in Linux kernels: 3.18–3.19, 4.0–4.6
• modules built: exynos5_bus, exynos_ppmu

Help text

This adds the DEVFREQ driver for Exynos5250 bus interface (vdd_int). It reads PPMU counters of memory controllers and adjusts the operating frequencies and voltages with OPP support.
