From e932d817866770d456815c9a84b7ed94f0589d80 Mon Sep 17 00:00:00 2001 From: David Barksdale Date: Tue, 4 Feb 2014 12:42:48 -0600 Subject: HID: add hid-cp2112 driver This patch adds support for the Silicon Labs CP2112 "Single-Chip HID USB to SMBus Master Bridge." This is a HID device driver which registers as an i2c adapter and gpiochip to expose these functions of the CP2112. The customizable USB descriptor fields are exposed as sysfs attributes. The SMBus byte-read, byte-data-read/write, and word-data-read transfer modes have been tested by talking to an i2c sensor. The GPIO functions and USB descriptor field programming have also been tested.
