Subject: [PATCH 0/2] soc: qcom: rpmhpd: Improve rpmhpd enable handling
Date: Fri,  2 Jul 2021 17:54:14 -0700	[thread overview]
Message-ID: <20210703005416.2668319-1-bjorn.andersson@linaro.org> (raw)

During the discussion and investigation of [1] it became apparent that
enabling a rpmhpd, without requesting a performance state is a nop. This
results in a situation where drivers that normally would just describe
their dependency on the power-domain and have the core implicitly enable
that power domain also needs to make an explicit vote for a performance
state - e.g. by a lone required-opp.
