From 6abf32f1d9c5009dcccded2c1e7ca899a4ab587b Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Thu, 10 Feb 2022 11:19:45 +0530 Subject: cpuidle: Add RISC-V SBI CPU idle driver The RISC-V SBI HSM extension provides HSM suspend call which can be used by Linux RISC-V to enter platform specific low-power state. This patch adds a CPU idle driver based on RISC-V SBI calls which will populate idle states from device tree and use SBI calls to entry these idle states.
