Merge tag 'cpuidle-v5.13-rc1' of https://git.linaro.org/people/daniel.lezcano/linux
Pull ARM cpuidle updates for v5.13 from Daniel Lezcano: "- Fix the C7 state on the tegra114 by setting the L2-no-flush flag unconditionally (Dmitry Osipenko) - Remove the do_idle firmware call as it is not supported by the ATF on tegra SoC (Dmitry Osipenko) - Add a missing dependency on CONFIG_MMU to prevent linkage error (He Ying)" * tag 'cpuidle-v5.13-rc1' of https://git.linaro.org/people/daniel.lezcano/linux: cpuidle: Fix ARM_QCOM_SPM_CPUIDLE configuration cpuidle: tegra: Remove do_idle firmware call cpuidle: tegra: Fix C7 idling state on Tegra114
