Subject: [PATCH 0/2] OPP/pmdomain: Assign the correct required-dev
Date: Tue, 3 Sep 2024 00:48:13 +0200 [thread overview]
Message-ID: <20240902224815.78220-1-ulf.hansson@linaro.org> (raw)
The recent series for OPP/pmdomains [1] that has been queued for v6.12 via the
pmdomain tree introduces a regression for the Qcom Venus driver, which was
reported to me offlist.
This small series attempts to fix the problem by making the assignment of the
required-devs more robust and correct. More details are available in the commit
messages.
I have tested this on specific test setup with Qemu, trying to model all the
various way required-opps are being used. I would appreciate help with further
test on HW and reviews, of course!
Kind regards
Ulf Hansson
