Andriy Gapon c178a7e73c cp2112: driver for the namesake GPIO and I2C master gadget ... Documentation: - CP2112 Datasheet https://www.silabs.com/documents/public/data-sheets/cp2112-datasheet.pdf - AN495: CP2112 Interface Specification https://www.silabs.com/documents/public/application-notes/an495-cp2112-interface-specification.pdf - CP2112 Errata https://www.silabs.com/documents/public/errata/cp2112-errata.pdf The logic is implemented as three sub-drivers. The parent driver claims the USB device and creates two child devices. One acts as a GPIO controller and the other is an I2C controller. Tested with CP2112 revision F02. Both features seem to work. HTU21 sensor was used as an I2C slave. Reviewed by: adrian, hselasky MFC after: 2 weeks Relnotes: maybe Differential Revision: https://reviews.freebsd.org/D25359		2020-08-06 13:41:42 +00:00
