Subject: [PATCH v3 0/2] Technologic I2C-FPGA gpio support

This driver aims to support all Technologic Systems's boards embedding FPGA
GPIOs with an I2C interface.

Changes in v2:
 - convert from bool to tristate

Changes in v3:
 - use regmap abstraction to read/write from I2C
 - use devm_gpiochip_add_data()
 - implement ts4900_gpio_get_direction() function
 - use explicit bit names (GPIO_IN/GPIO_OUT)
 - fix ts4900_gpio_set() function (do not force the line as output)
 - doc: document ngpios property
