[PATCH v1 4/7] arm64: dts: ti: k3-am62-verdin: Add Zinnia
From: Francesco Dolcini
Date: Tue Mar 24 2026 - 05:44:41 EST
From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>
Add Zinnia Carrier Board mated with Verdin AM62.
It features 1 x RS232, 1 x RS485, 1 x CAN, 3 x isolated digital I/O,
2 x 1GBit/s Ethernet, a mini PCIe slot with USB / SIM card connector
for a modem, USB and SD card interfaces.
