From 82741978e25036e4805d43621a575995f4edeb86 Mon Sep 17 00:00:00 2001 From: Kalesh Singh Date: Thu, 30 Jun 2022 19:12:29 +0000 Subject: pm/sleep: Add PM_USERSPACE_AUTOSLEEP Kconfig Systems that initiate frequent suspend/resume from userspace can make the kernel aware by enabling PM_USERSPACE_AUTOSLEEP config. This allows for certain sleep-sensitive code (wireguard/rng) to decide on what preparatory work should be performed (or not) in their pm_notification callbacks. This patch was prompted by the discussion at [1] which attempts to remove CONFIG_ANDROID that currently guards these code paths.
