Subject: [PATCH 1/5] dt-bindings: qcom: se-common: Add QUP Peripheral-specific
|
|
properties for I2C, SPI, and SERIAL bus
|
|
|
|
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.

+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.
