Subject: [PATCH 09/16] dt-bindings: firmware: arm,scmi: Extend bindings for protocol@13
Date: Wed, 7 Jun 2023 14:46:21 +0200 [thread overview]
Message-ID: <20230607124628.157465-10-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20230607124628.157465-1-ulf.hansson@linaro.org>
The protocol@13 node is describing the performance scaling option for the
ARM SCMI interface, as a clock provider. This is unnecessary limiting, as
performance scaling is in many cases not limited to switching a clock's
frequency.
Therefore, let's extend the binding so the interface can be modelled as a
generic "performance domain" too. The common way to describe this, is to
use the "power-domain" bindings, so let's use that.
