Subject: cpuidle: add ARCH_SUSPEND_POSSIBLE dependencies
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 7787943a3a8ade6594a68db28c166adbb1d3708c upstream.
Some ARMv4 processors don't support suspend, which leads
to a build failure with the tegra and qualcomm cpuidle driver:
WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND
Depends on [n]: ARCH_SUSPEND_POSSIBLE [=n]
Selected by [y]:
- ARM_TEGRA_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64) && (ARCH_TEGRA [=n] || COMPILE_TEST [=y]) && !ARM64 && MMU [=y]
arch/arm/kernel/sleep.o: in function `__cpu_suspend':
(.text+0x68): undefined reference to `cpu_sa110_suspend_size'
(.text+0x68): undefined reference to `cpu_fa526_suspend_size'
Add an explicit dependency to make randconfig builds avoid
this combination.
Fixes: faae6c9f2e68 ("cpuidle: tegra: Enable compile testing")
Fixes: a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver")
