GENI Serial Engine QUP Wrapper Controller + +Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) wrapper +is a programmable module for supporting a wide range of serial interfaces +like UART, SPI, I2C, I3C, etc. A single QUP module can provide upto 8 Serial +Interfaces, using its internal Serial Engines. The GENI Serial Engine QUP +Wrapper controller is modeled as a node with zero or more child nodes each +representing a serial engine. + +Required properties: +- compatible: Must be "qcom,geni-se-qup". +- reg: Must contain QUP register address and length. +- clock-names: Must contain "m-ahb" and "s-ahb". +- clocks: AHB clocks needed by the device. + +Required properties if child node exists: +- #address-cells: Must be 1 +- #size-cells: Must be 1 +- ranges: Must be present + +Properties for children: + +A GENI based QUP wrapper controller node can contain 0 or more child nodes +representing serial devices.
