CM4 based PTP / SyncE 1G Switch with optional GPS

Switchberry is a Raspberry Pi CM4–controlled Ethernet switching + timing platform built around a Microchip KSZ9567 and a Renesas 8A34004 ClockMatrix DPLL. It’s designed for PTP / SyncE / timing lab use cases, to build out a PTP network with Sync-E support.
