Subject: [RFC][PATCH 0/2] Introduce 'advanced' Energy Model in DT
Date: Mon, 21 Feb 2022 22:51:29 +0000 [thread overview]
Message-ID: <20220221225131.15836-1-lukasz.luba@arm.com> (raw)
Hi all,
This patch set solves a few issues:
1. It allows to register EM from DT, when the voltage information is not
available. (Some background of the issues present on Chromebook devices
can be checked at [1].)
2. It allows to register 'advanced' EM from the DT, which is more accurate
and reflects total power (dynamic + static).
Implementation details:
It adds a new callback in OPP framework to parse the "energy-model" DT
entry. The propsed DT bindings heavily draw on "operating-points" (v1)
schema.
Comments, suggestions are very welcome.
Regards,
Lukasz Luba
