+Qualcomm Technologies, Inc. GENI Serial Engine QUP Wrapper Controller
+Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP)
+is a programmable module for supporting a wide range of serial
+like UART, SPI, I2C, I3C, etc. A single QUP module can provide upto 8
+Interfaces, using its internal Serial Engines. The GENI Serial Engine
+Wrapper controller is modeled as a node with zero or more child nodes
+representing a serial engine.
+- 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> for Serial Engine Address
+- #size-cells: Must be <1> for Serial Engine Address
+- ranges: Must be present
+Properties for children:
+A GENI based QUP wrapper controller node can contain 0 or more child
+representing serial devices. These serial devices can be a QCOM UART,
+controller, spi controller, or some combination of aforementioned
Where's the SPI binding?
Since the patch series introduces UART and I2C drivers, I added the bindings
only for them. I thought about adding the SPI binding when the SPI
controller driver is introduced. Please let me know if you want me to add
the bindings for SPI in this patch series itself.
There's no requirement to have the driver and I prefer bindings be as
complete as possible.
Ok, I will add the bindings for SPI controller in the next posting.
