Subject: [PATCH 0/8] Flush RSC votes properly on more RPMh platforms
Date: Wed, 31 May 2023 15:22:34 +0200	[thread overview]
Message-ID: <20230531-topic-rsc-v1-0-b4a985f57b8b@linaro.org> (raw)

As pointed out in [1], the Linux implementation of RSC basically requires
(even if not explicitly) that we point it to a power domain which
represents the power state of the CPUs. In an effort to fulfill that
requirement, make it required in bindings and hook it up on all platforms
where I was able to do. This means all RPMh platforms, except

- SC7180
- SC7280
- SA8775

As there wasn't an idle-states setup (which may be on purpose for CrOS
devices, certainly not for Windows SC7[12]80s) that I could validate.
(Doug, Bartosz, could you guys look into your respective platforms of
interest here?)

This series also adds support for idle states on SM6350, as I was able
to add and test that.
