Subject: [PATCH] cpuidle: psci: Extend information in log about OSI/PC mode
Date: Thu, 20 Oct 2022 13:55:13 +0200 [thread overview]
Message-ID: <20221020115513.93809-1-ulf.hansson@linaro.org> (raw)
It's useful to understand whether we are using OS-initiated (OSI) mode or
Platform Coordinated (PC) mode, when initializing the CPU PM domains.
Therefore, let's extend the print in the log after a successful probe with
this information.
