2016-10-24USB: serial: ch341: reinitialize chip on reconfigurationAidan Thornton
Changing the LCR register after initialization does not seem to be reliable on all chips (particularly not on CH341A). Restructure initialization and configuration to always reinit the chip on configuration changes instead and pass the LCR register value directly to the initialization command. (Note that baud rates above 500kbaud are incorrect, but they're incorrect in the same way both before and after this patch at least on the CH340G. Fixing this isn't a priority as higher baud rates don't seem that reliable anyway.)

2016-10-24USB: serial: cp210x: Adding GPIO support for CP2105Martyn Welch
This patch adds support for the GPIO found on the CP2105. Unlike the GPIO provided by some of the other devices supported by the cp210x driver, the GPIO on the CP2015 is muxed on pins otherwise used for serial control lines. The GPIO have been configured in 2 separate banks as the choice to configure the pins for GPIO is made separately for pins shared with each of the 2 serial ports this device provides, though the choice is made for all pins associated with that port in one go. The choice of whether to use the pins for GPIO or serial is made by adding configuration to a one-time programable PROM in the chip and can not be changed at runtime. The device defaults to GPIO. This device supports either push-pull or open-drain modes, it doesn't provide an explicit input mode, though the state of the GPIO can be read when used in open-drain mode. Like with pin use, the mode is configured in the one-time programable PROM and can't be changed at runtime.
