move s3c24xx-irq to drivers/irqchip and add dt support
From: Heiko Stuebner <heiko@...> Date: Fri, 22 Mar 2013 16:43:13 +0100
As suggested by Rob Herring move back to get the parent releationship from dt like in the first versions, but set the handler from the interrupt property rather than from a specific list. This version also implements (hopefully correctly) an idea from him and Arnd Bergmann to have the parent relationship not described in the controller node but the device nodes instead. Therefore the main controller continues to use a two-cell descriptor to set hwirq and trigger type but the sub-controller switches to a three-cell descriptor where the third bit describes the hwirq of its parent irq in the main controller. As a result a serial node would then look like: serial@50000000 { compatible = "samsung,s3c2410-uart"; reg = <0x50000000 0x4000>; interrupt-parent = <&subintc>; interrupts = <0 4 28>, <1 4 28>; }; Tested on a s3c2416-based board. As it depends on changes already pending for 3.10 it should probably go thru the samsung tree.
