From: Arnd Bergmann Date: Sun, 28 Feb 2016 03:18:27 +0000 (+0800) Subject: ARM: imx: select ARM_CPU_SUSPEND only for imx6 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b4042a4c01b815f2fa63d237b9fe03204b7ab232;p=linux-beck.git ARM: imx: select ARM_CPU_SUSPEND only for imx6 i.MX only needs to select ARM_CPU_SUSPEND manually for the very specific case that CONFIG_PM_SLEEP is disabled and imx6 is used with CONFIG_PM enabled for runtime PM. If we are building a kernel only for CPUs that are not using the cpu_suspend() helper, we otherwise get a harmless build warning: warning: (ARCH_MXC && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM && EXYNOS_CPU_SUSPEND && ARCH_VEXPRESS_TC2_PM && ARM_BIG_LITTLE_CPUIDLE && ARM_HIGHBANK_CPUIDLE && QCOM_PM) selects ARM_CPU_SUSPEND which has unmet direct dependencies (ARCH_SUSPEND_POSSIBLE) This moves the option to the SOC_IMX6 option that actually requires it, in effect reverting commit f36b594f3754 ("ARM: mach-imx: Select ARM_CPU_SUSPEND at ARCH_MXC level") that was meant as a cleanup and unintentionally caused this warning.
