I think I heard some noise about this the week before.

I think OMAP and DaVinci does someting similar too. This is from a recent
DaVinci patch from Keerthy:
+Example for 66AK2G:
+
+gpio0: gpio@2603000 {
+ compatible = "ti,k2g-gpio", "ti,keystone-gpio";
+ reg = <0x02603000 0x100>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ interrupts = <GIC_SPI 432 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 433 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 434 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 435 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 436 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 437 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 438 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 439 IRQ_TYPE_EDGE_RISING>,
+ <GIC_SPI 440 IRQ_TYPE_EDGE_RISING>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ ti,ngpio = <144>;
+ ti,davinci-gpio-unbanked = <0>;
+ clocks = <&k2g_clks 0x001b 0x0>;
+ clock-names = "gpio";
+};
That looks fairly similar.
