2013-06-12	gpio: samsung: Remove OF support for s3c24xx	Sylwester Nawrocki	1	-43/+0
	There is no users of this code and there is already a pinctrl driver written for s3c24xx which is going to be used on any s3c24xx DT platforms. Hence this has been effectively a dead code in mainline. This reverts commit 172c6a13653ac8cd6a231293b87c93821e90c1d6 gpio: samsung: add devicetree init for s3c24xx arches Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Acked-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2012-09-07	gpio: samsung: add devicetree init for s3c24xx arches	Heiko Stuebner	1	-0/+43
	Until now the EXYNOS-SoC was the only Samsung-SoC supporting the GPIOs via the device tree. This patch implements dt-support for the s3c24xx arches. The controllers contain only 3 cells, as the underlying gpio controller does not support controlling the drive strength on a gpio level. Tested with the gpio-keys driver on a s3c2416 based machine.

2012-07-17	gpio: samsung: add flags specifier to device-tree binding	Olof Johansson	1	-4/+5
	This adds a flags field to the gpio specifier for Samsung. I didn't want to add yet another field in the already quite long specifier, so I decided to compress it together with the Pull Up/Down settings instead. This is needed to, for example, have a gpio-keys input that is active low. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2011-12-23	gpio/samsung: Add device tree support for EXYNOS4	Thomas Abraham	1	-0/+40
	As gpio chips get registered, a device tree node which represents the gpio chip is searched and attached to it. A translate function is also provided to convert the gpio specifier into actual platform settings for pin function selection, pull up/down and driver strength settings.
