2014-02-18HID: add hid-cp2112 driverDavid Barksdale1-0/+1066
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. Signed-off-by: David Barksdale <dbarksdale@uplogix.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
