Tue Jan 21 01:33:29 PST 2025
This patch adds support for the Variscite Concerto Carrier Board.
This Carrier-Board has the following:
- LVDS interface for the VLCD-CAP-GLD-LVDS 7" LCD 800 x 480 touch
display (not configured)
- USB Host + USB OTG Connector
- 10/100 Mbps Ethernet
- miniPCI-Express slot
- SD Card connector
- Audio Headphone/Line In jack connectors
- S-ATA
- On-board DMIC
Product Page: https://www.variscite.com/product/single-board-computers/concerto-board
This file is based on the one provided by Variscite on their own kernel,
but adapted for mainline.
