From: Bharat Kumar Gogada
Date: Wed Jun 08 2022 - 12:41:24 EST
Xilinx Versal Premium series has CPM5 block which supports Root Port functioning at Gen5 speed.
Xilinx Versal CPM5 has few changes with existing CPM block.
- CPM5 has dedicated register space for control and status registers.
- CPM5 legacy interrupt handling needs additonal register bit
to enable and handle legacy interrupts.
Changes in v4:
- Removed versioning in compatible string
- reg property definitions are added
