From 40dbea961a3d92a7dec92a72c18ee03d33ccc52a Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 12 Jan 2023 20:43:50 +0100 Subject: cpuidle, OMAP3: Use WFI for omap3_pm_idle() arch_cpu_idle() is a very simple idle interface and exposes only a single idle state and is expected to not require RCU and not do any tracing/instrumentation. As such, omap_sram_idle() is not a valid implementation. Replace it with the simple (shallow) omap3_do_wfi() call. Leaving the more complicated idle states for the cpuidle driver.
