2012-08-17	gpio: Fix debug message in of_get_named_gpio_flags()	Thierry Reding	1	-1/+1
	This was probably missed in the conversion done in commit 3d0f7cf ("gpio: Adjust of_xlate API to support multiple GPIO chips"). Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-07-17	gpio: of_get_named_gpio_flags() return -EPROBE_DEFER if GPIO not yet available	Roland Stigge	1	-1/+4
	of_get_named_gpio_flags() and of_get_named_gpio() return -EPROBE_DEFER if the respective GPIO is not (yet) available. This is useful if driver's probe() functions try to get a GPIO whose controller isn't probed yet. Thus, the driver can be probed again later on. The function still returns -EINVAL on other errors (parse error or node doesn't exist). This way, the case of an optional/intentionally missing GPIO is handled appropriately.

2012-07-17	gpio: propagate of_parse_phandle_with_args errors	Alexandre Courbot	1	-1/+1
	Make of_get_named_gpio_flags propagate any error it receives from of_parse_phandle_with_args instead of inconditionally returning -EINVAL. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2012-05-18	gpio: Adjust of_xlate API to support multiple GPIO chips	Grant Likely	1	-42/+38
	This patch changes the of_xlate API to make it possible for multiple gpio_chips to refer to the same device tree node. This is useful for banked GPIO controllers that use multiple gpio_chips for a single device. With this change the core code will try calling of_xlate on each gpio_chip that references the device_node and will return the gpio number for the first one to return 'true'.

2012-04-07	gpio: Move DT support code into drivers/gpio	Grant Likely	1	-0/+240
	The code in drivers/of/gpio.c isn't shared by any other subsystem since it is all gpiolib specific. drivers/gpio is a better place to maintain these functions.
