The first one has all the 144 GPIOs functional. 9 banks with 16 gpios making a total of 144. The second instance has only the GPIO0:GPIO67 functional and rest are marked reserved. Signed-off-by: Keerthy Acked-by: Linus Walleij --- Changes in v4: * Couple of rephrasing in the commit log. * Changed compatible to ti,k2g-gpio. Changes in v2: * Split the documentation part into a separate patch. arch/arm/boot/dts/keystone-k2g.dtsi | 42 +++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) diff --git a/arch/arm/boot/dts/keystone-k2g.dtsi b/arch/arm/boot/dts/keystone-k2g.dtsi index bf4d1fa..4eb1ba8 100644 --- a/arch/arm/boot/dts/keystone-k2g.dtsi +++ b/arch/arm/boot/dts/keystone-k2g.dtsi @@ -15,6 +15,7 @@ #include #include +#include / { compatible = "ti,k2g","ti,keystone"; @@ -168,5 +169,46 @@ #reset-cells = <2>; }; }; + + gpio0: gpio@2603000 { + compatible = "ti,k2g-gpio", "ti,keystone-gpio"; + reg = <0x02603000 0x100>; + gpio-controller; + #gpio-cells = <2>; + + interrupts = , + , + , + , + , + , + , + , + ; + interrupt-controller; + #interrupt-cells = <2>; + ti,ngpio = <144>; + ti,davinci-gpio-unbanked = <0>; + clocks = <&k2g_clks 0x001b 0x0>; + clock-names = "gpio"; + }; + + gpio1: gpio@260a000 { + compatible = "ti,k2g-gpio", "ti,keystone-gpio"; + reg = <0x0260a000 0x100>; + gpio-controller; + #gpio-cells = <2>; + interrupts = , + , + , + , + ; + interrupt-controller; + #interrupt-cells = <2>; + ti,ngpio = <68>; + ti,davinci-gpio-unbanked = <0>; + clocks = <&k2g_clks 0x001c 0x0>; + clock-names = "gpio"; + }; }; }; -- 1.9.1
