Subject: [PATCH v3 0/5] pmdomain/cpuidle-psci: Fix behaviours for CPU PM domains
Date: Mon,  7 Sep 2026 13:16:50 +0200	[thread overview]
Message-ID: <20260907111659.263324-1-ulf.hansson@oss.qualcomm.com> (raw)

From: Ulf Hansson <ulfh@kernel.org>

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 v3:
	- Minor updates to patch1 and patch2.
	- Added tested/reviewed-by tags.

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

Kind regards
Uffe
