This series adds cpuidle support for Tegra194 carmel CPUs.

MCE firmware is responsible for deciding on CPU idle power state
based on state information and MCE firmware background work.

Tegra MCE ARI driver is the interface driver to communicate with
MCE firmware from the kernel.

CPU idle driver passes idle state information to MCE through Tegra
MCE driver and requests idle state transition to MCE happens through
PSCI CPU suspend.

This series includes below patches
- Add CPUIDLE section to MAINTAINERS
- Add Tegra MCE ARI driver to communicate with MCE firmware from kernel
- Add dt-bindings for Tegra194 cpu idle states
- Add cpuidle driver to support Tegra194 CPUs idle state management
- Update Tegra194 device tree with cpuidle support to Tegra194 CPUs.
