examples:
The I2C Master Hub is a stripped down version of the GENI Serial Engine QUP Wrapper Controller but only supporting I2C serial engines without DMA support. This documents the variant compatible and forbids UART and SPI sub-nodes, and removes requirement for the Master AHB clock and iommu property.
