[PATCH v2 0/5] pmdomain/cpuidle-psci: Fix behaviours for CPU PM domains

From: Ulf Hansson

Date: Tue Sep 01 2026 - 07:21:41 EST


From: Ulf Hansson <ulfh@xxxxxxxxxx>

This series fixes a couple of different, but highly related problems, when
dealing with CPU PM domains. More details are available in the commit messages
for each patch.

Note that, this series is a follow up to fix problems that have been pointed
out in a series [1] from Yuanfang Zhang (Qcom), to add support for new
components for the arm coresight subsystem.

Changes in v2:
- Dropped the RFC.
- See updates in the changelog for each patch.

Kind regards
Uffe
