[PATCH 1/3] qcom: spm: allow compile-testing

[PATCH 1/3] qcom: spm: allow compile-testing

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

ARM_QCOM_SPM_CPUIDLE can be selected when compile-testing on
other architectures, but this causes a Kconfig warning
for QCOM_SPM:

WARNING: unmet direct dependencies detected for QCOM_SPM
  Depends on [n]: ARCH_QCOM [=n]
  Selected by [y]:
  - ARM_QCOM_SPM_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64) && (ARCH_QCOM [=n] || COMPILE_TEST [=y]) && !ARM64 && MMU [=y]

Make it possible to also compile-test this one, which can
be done now that v5.15-rc5 lets you select QCOM_SCM everywhere.

Fixes: a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver")
Fixes: 498ba2a8a275 ("cpuidle: Fix ARM_QCOM_SPM_CPUIDLE configuration")

Bjorn, if you think this is the right solution, let me know and I can
apply it on top of the drivers branch that I have already pulled
into the soc tree.

Alternatively, this could go through the cpuidle tree, along with
the other two patches.

[PATCH 2/3] cpuidle: tegra: add ARCH_SUSPEND_POSSIBLE dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Some StrongARM processors don't support suspend, which leads
to a build failure with the tegra 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'

Add an explicit dependency to make randconfig builds avoid
this combination.
