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

From: Lucile Quirion
Date: Thu Aug 11 2016 - 16:32:24 EST


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

gpio: add bindings for Technologic I2C-FPGA gpio controller
