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 Lucile Quirion (2): gpio: add bindings for Technologic I2C-FPGA gpio controller gpio: add Technologic I2C-FPGA gpio support .../devicetree/bindings/gpio/gpio-ts4900.txt | 29 +++ drivers/gpio/Kconfig | 6 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-ts4900.c | 198 +++++++++++++++++++++ 4 files changed, 234 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-ts4900.txt create mode 100644 drivers/gpio/gpio-ts4900.c -- 2.5.5
