[PATCH v2 0/2] PCI/pwrctrl: A couple of fixes
From: Manivannan Sadhasivam via B4 Relay
Date: Mon Feb 23 2026 - 09:47:57 EST
Hi,
This series fixes a couple of issues introduced in the recent pwrctrl rework
for v7.0. Both issues are due to some incorrect assumptions on deciding when to
create pwrctrl devices. First issue is due to assuming that all OF graph nodes
require pwrctrl and another one is due to assuming that all PCI child nodes are
PCI devices.
Both issues are fixed by changing the pwrctrl device creation logic in
pwrctrl/core.
Testing
=======
This series is tested on Lenovo Thinkpad T14s.
Note for Bjorn H
================
Even though only patch 1 is fixing a regression on the IPQ board which was not
part of the testbed of the pwrctrl rework went in for v7.0, patch 2 is also
fixing an actual issue, but it is not impacting any of the current upstream
supported platforms. But I'd like to get these two patches merged for v7.0 so
that both the issues are fixed in the same major release where the issues
originated.
