[PATCH v4 1/5] dt-bindings: qcom: se-common: Add QUP Peripheral-specific properties for I2C, SPI, and SERIAL bus
From: Viken Dadhaniya
Date: Sat May 03 2025 - 07:11:18 EST
Introduce a new YAML schema for QUP-supported peripherals. Define common
properties used across QUP-supported peripherals.
Add property `qcom,enable-gsi-dma` to configure the Serial Engine (SE) for
QCOM GPI DMA mode.
Reference the common schema YAML in the GENI I2C, SPI, and SERIAL YAML
files.

v1 -> v2:
- Update qcom,gsi-dma-allowed property name to qcom,enable-gsi-dma.
- Remove full stop form title.
- Add reference of common schema YAML in the I2C, SPI, and SERIAL YAML files.
