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.
