Subject: [PATCH 07/13] dt-bindings: avs: cpr: Convert binding to YAML schema
Date: Thu, 26 Nov 2020 19:45:53 +0100 [thread overview]
Message-ID: <20201126184559.3052375-8-angelogioacchino.delregno@somainline.org> (raw)
In-Reply-To: <20201126184559.3052375-1-angelogioacchino.delregno@somainline.org>
Convert the qcom,cpr.txt document to YAML schema and place it in the
appropriate directory, since commit a7305e684fc moves this driver
from power/avs to soc/qcom, but forgets to move the documentation.

-QCOM CPR (Core Power Reduction)
-
-CPR (Core Power Reduction) is a technology to reduce core power on a CPU
-or other device. Each OPP of a device corresponds to a "corner" that has
-a range of valid voltages for a particular frequency. While the device is
-running at a particular frequency, CPR monitors dynamic factors such as
-temperature, etc. and suggests adjustments to the voltage to save power
-and meet silicon characteristic requirements.
-
-- compatible:
- Usage: required
- Value type: <string>
