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
