2018-05-16	gpio: loongson: Use BIT() macros	Linus Walleij	1	-14/+11
	This switches the Loongson driver over to using the bitops BIT() macros and drops some local variables and make the code easier to read (in my opinion).

2018-05-16	gpio: loongson: Create a dynamic platform device	Linus Walleij	1	-10/+37
	It is pretty helpful to create some kind of device for backing the GPIO chips, especially when preparing the driver for using GENERIC_GPIO, so let's create a simple platform device and a simple platform device driver and create the gpiochip in the .probe() routine for the device driver. Keep all at the core initcall so the behaviour is the same as before.

2018-05-16	gpio: loongson: Use right include	Linus Walleij	1	-33/+33
	The driver includes <linux/gpio.h> which is wrong, rely on <linux/gpio/driver.h> and remove to call to gpio_set_value() in favor of calling the internal function. Move functions around to avoid forward declarations.

2016-01-05	gpio: convert remaining users to gpiochip_add_data()	Linus Walleij	1	-1/+1
	For completion, sweep the floor from all gpiochip_add() usage so we can remove that function and get rid of the function wrapper gpiochip_add(). Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-04-08	gpio: loongson: Add Loongson-3A/3B GPIO driver support	Huacai Chen	1	-17/+27
	Improve Loongson-2's GPIO driver to support Loongson-3A/3B, and update Loongson-3's default config file.

2015-04-07	MIPS: Move Loongson GPIO driver to drivers/gpio	Huacai Chen	1	-0/+105
