Subject: [PATCH v2 08/11] dt-bindings: firmware: arm,scmi: Extend bindings for protocol@13
Date: Thu, 13 Jul 2023 16:17:35 +0200 [thread overview]
Message-ID: <20230713141738.23970-9-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20230713141738.23970-1-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 domaintoo. The common way to describe this, is to use
the "power-domain" DT bindings, so let's use that.

Changes in v2:
- Updated the DT binding to require "oneOf" #power-domain-cells or
#clock-cells.
