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.

title: QUP Peripheral-specific properties for I2C, SPI and SERIAL bus
|
|
|
|
description:
|
|
The Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) is
|
|
a programmable module that supports a wide range of serial interfaces
|
|
such as UART, SPI, I2C, I3C, etc. This defines the common properties used
|
|
across QUP-supported peripherals.
