[PATCH v4 11/14] riscv: dts: microchip: refactor icicle kit device tree

Mon Jan 17 03:07:52 PST 2022


From: Conor Dooley <conor.dooley at microchip.com>

Assorted minor changes to the MPFS/Icicle kit device tree:

- rename serial to mmuart to match microchip documentation
- move phy0 inside mac1 node to match phy configuration
- add labels where missing (cpus, cache controller)
- add missing address cells & interrupts to MACs
