From 5763318f562fc0b30f729dce531b2982e29db463 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Tue, 23 Jul 2013 13:06:04 +0530 Subject: gpio: palmas: add dt support Add of_device_id table for Palma GPIO to be enable the driver from DT file. The driver can be registered from DT file as: palmas: tps65913@58 { ::::::::::: palmas_gpio: palmas_gpio { compatible = "ti,palmas-gpio"; gpio-controller; #gpio-cells = <2>; }; }; Signed-off-by: Laxman Dewangan Acked-by: Stephen Warren Signed-off-by: Linus Walleij --- .../devicetree/bindings/gpio/gpio-palmas.txt | 27 ++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-palmas.txt (limited to 'Documentation/devicetree/bindings/gpio') diff --git a/Documentation/devicetree/bindings/gpio/gpio-palmas.txt b/Documentation/devicetree/bindings/gpio/gpio-palmas.txt new file mode 100644 index 000000000000..08b5b52a3ae0 --- /dev/null +++ b/Documentation/devicetree/bindings/gpio/gpio-palmas.txt @@ -0,0 +1,27 @@ +Palmas GPIO controller bindings + +Required properties: +- compatible: + - "ti,palams-gpio" for palma series of the GPIO controller + - "ti,tps80036-gpio" for Palma series device TPS80036. + - "ti,tps65913-gpio" for palma series device TPS65913. + - "ti,tps65914-gpio" for palma series device TPS65914. +- #gpio-cells : Should be two. + - first cell is the gpio pin number + - second cell is used to specify the gpio polarity: + 0 = active high + 1 = active low +- gpio-controller : Marks the device node as a GPIO controller. + +Note: This gpio node will be sub node of palmas node. + +Example: + palmas: tps65913@58 { + ::::::::::: + palmas_gpio: palmas_gpio { + compatible = "ti,palmas-gpio"; + gpio-controller; + #gpio-cells = <2>; + }; + ::::::::::: + }; -- cgit v1.2.3
