2018-07-29	gpio-pisosr: add support for get_multiple	Morten Hein Tiljeset	1	-0/+22

2016-09-13	gpio: constify gpio_chip structures	Julia Lawall	1	-1/+1
	These structures are only used to copy into other structures, so declare them as const. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct gpio_chip i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct gpio_chip e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct gpio_chip i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-25	gpio: pisosr: Use gpiod_set_value_cansleep in pisosr_gpio_refresh()	Axel Lin	1	-2/+2
	This driver has .can_sleep flag set. So the pisosr_gpio_get() can be called from contexts that can sleep. Thus use the cansleep() variant in pisosr_gpio_refresh(). Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-25	gpio: pisosr: Use devm_gpiod_get_optional for gpio->load_gpio	Axel Lin	1	-7/+4
	gpio->load_gpio is optional, so use devm_gpiod_get_optional instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-19	gpio: pisosr: add missing unlock	Sudip Mukherjee	1	-3/+1
	If spi_read() fails then we just returned but we missed unlocking the mutex. Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-10	gpio: Add driver for SPI serializers	Andrew F. Davis	1	-0/+188
	Add generic parallel-in/serial-out shift register GPIO driver. This includes SPI compatible devices like SN74165 serial-out shift registers and the SN65HVS88x series of industrial serializers that can be read over the SPI bus and used for GPI (General Purpose Input).
