Subject: [PATCH] Add support of TI ICDI to USB simple serial device
Date:   Fri, 26 Oct 2018 19:38:07 +0800
Message-Id: <20181026113807.20735-1-dscao999@gmail.com>

Precedence: bulk

TI In-Circuit Debug Interface (ICDI) is a debugging interface for TI ARM microcontrollers. It has four USB interfaces and the first two of them are presented as standard ACM serial device. The 3rd interface is the debugging interface and it can be driven as a Linux USB simple serial device. With it, debugging sessions and firmware up/down loading are supported on Linux.
