From 9d881361206ebcf6285c2ec2ef275aff80875347 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 21 Sep 2021 12:42:25 +0300 Subject: bus: ti-sysc: Add quirk handling for reinit on context lost Some interconnect target modules such as otg and gpmc on am335x need a re-init after resume. As we also have PM runtime cases where the context may be lost, let's handle these all with cpu_pm. For the am335x resume path, we already have cpu_pm_resume() call cpu_pm_cluster_exit().
