RISC-V CPU Idle Support
This series adds RISC-V CPU Idle support using SBI HSM suspend function. The RISC-V SBI CPU idle driver added by this series is highly inspired from the ARM PSCI CPU idle driver. Special thanks Sandeep Tripathy for providing early feeback on SBI HSM support in all above projects (RISC-V SBI specification, OpenSBI, and Linux RISC-V). * palmer/riscv-idle: RISC-V: Enable RISC-V SBI CPU Idle driver for QEMU virt machine dt-bindings: Add common bindings for ARM and RISC-V idle states cpuidle: Add RISC-V SBI CPU idle driver cpuidle: Factor-out power domain related code from PSCI domain driver RISC-V: Add SBI HSM suspend related defines RISC-V: Add arch functions for non-retentive suspend entry/exit RISC-V: Rename relocate() and make it global RISC-V: Enable CPU_IDLE drivers
