Key features included are: - Clock configuration - PHY configuration - Interrupt configuration (enabling) The clock divider block, built on top of the Cadence xSPI IP, divides an external 800MHz clock. It supports a limited range of clock speeds from 6.25MHz to 200MHz. To manage interrupts correctly, the driver needs to clear both the MSI-X interrupt bit and the xSPI interrupt bit. Additionally, interrupt masking must be disabled.
