Before commit d6f346f (cpuidle: improve governor Kconfig options),
the CONFIG_ARCH_NEEDS_CPU_IDLE_COUPLED option didn't depend on
CONFIG_CPU_IDLE but now it has been moved under the CPU_IDLE
menuconfig.
That raises the following warnings:
warning: (ARCH_OMAP4 && ARCH_TEGRA_2x_SOC) selects ARCH_NEEDS_CPU_IDLE_COUPLED
which has unmet direct dependencies (CPU_IDLE)
warning: (ARCH_OMAP4 && ARCH_TEGRA_2x_SOC) selects ARCH_NEEDS_CPU_IDLE_COUPLED
which has unmet direct dependencies (CPU_IDLE)
because the tegra2 and omap4 Kconfig files select this option
without checking if CPU_IDLE is set.
Fix that by moving ARCH_NEEDS_CPU_IDLE_COUPLED outside of CPU_IDLE.

CPU idle is a generic framework for supporting software-controlled
|
|
idle processor power management. It includes modular cross-platform
|
|
governors that can be swapped during runtime.
|
|
|
|
If you're using an ACPI-enabled platform, you should say Y here.

This is useful if you have a system with different CPU latencies and

states. If unsure say N.
