[PATCH] Implement driver for Topaz signature pads

2017-04-07 Thread Alyssa Rosenzweig
This patch adds a new driver targeting the T-LBK766SE-BHSB-R. This model is a 320x240 signature pad communicating via USB HID packets. Optionally, it can also communicate over RS-232, but this is not supported in this patch. Enough of the protocol itself is implemented here in order to blit bitmaps
