2016-10-21	gpio: ts4800: Fix module autoload	Javier Martinez Canillas	1	-0/+1
	If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/gpio/gpio-ts4800.ko \| grep alias $ After this patch: $ modinfo drivers/gpio/gpio-ts4800.ko \| grep alias alias: of:NTCtechnologic,ts4800-gpioC* alias: of:NTCtechnologic,ts4800-gpio Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-09-15	gpio: ts4800: fix implicit assumption module.h is present	Paul Gortmaker	1	-0/+1
	The Kconfig for this file is: drivers/gpio/Kconfig:config GPIO_TS4800 drivers/gpio/Kconfig: tristate "TS-4800 DIO blocks and compatibles" ...but however it does not include module.h -- it in turn gets it from another header (gpio/driver.h) and we'd like to replace that with a forward delcaration of "struct module;" but if we do, this file will fail to compile. So we fix this first to avoid putting build failures into the bisect commit history.

2016-02-23	gpio: ts4800: Use devm_gpiochip_add_data() for gpio registration	Laxman Dewangan	1	-11/+1
	Use devm_gpiochip_add_data() for GPIO registration and remove the need of driver callback .remove. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>
2016-02-16	gpio: TS-4800: remove useless bgpio_init flags	Julien Grossholtz	1	-2/+1
	No flags are required for bgpio_init in the TS-4800 gpio driver. This patch set zero instead. The driver will have the same behaviour since the & operator between the flags already resulted to zero.

2016-02-05	gpio: add TS-4800 fpga GPIO support	Julien Grossholtz	1	-0/+94
	The TS-4800 GPIO driver provide support for the GPIOs available on the Technologic Sytems board FPGA. It allows to set direction and read/write states. It uses the generic gpio driver.
