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
Changes in v4: - do not use deprecated gpio interface (linux/gpio.h) - select REGMAP_I2C
Lucile Quirion (2): gpio: add bindings for Technologic I2C-FPGA gpio controller gpio: add Technologic I2C-FPGA gpio support
