Subject: [PATCH 01/10] dt-bindings: pinctrl: qcom: create common LPASS LPI schema
Date:   Fri,  8 Dec 2023 22:55:25 +0100
Message-Id: <20231208215534.195854-1-krzysztof.kozlowski@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Just like regular TLMM pin controllers in Qualcomm SoCs, the Low Power
Audio SubSystem (LPASS) Low Power Island (LPI) TLMM blocks share a lot
of properties, so common part can be moved to separate schema to reduce
code duplication and make reviewing easier.

Except the move of common part, this introduces effective changes:
1. To all LPASS LPI bindings: Reference pinmux-node.yaml in each pin
   muxing and configuration node, to bring definition of "function" and
   "pins" properties.

2. qcom,sc7280-lpass-lpi-pinctrl: Reference pinctrl.yaml in top leve.
