2017-02-06ARCv2: IDU-intc: Use build registers for getting numbers of interruptsYuriy Kolerov1-0/+17
This enhancement is needed to allow masking all available common interrupts in IDU interrupt controller in boot time since the kernel can discover a number of them from the build register. Also now there is no need to specify in device tree a list of used core interrupts by IDU. E.g. before: idu_intc: idu-interrupt-controller { compatible = "snps,archs-idu-intc"; interrupt-controller; interrupt-parent = <&core_intc>; #interrupt-cells = <2>; interrupts = <24 25 26 27 28 29 30 31>; }; and after: idu_intc: idu-interrupt-controller { compatible = "snps,archs-idu-intc"; interrupt-controller; interrupt-parent = <&core_intc>; #interrupt-cells = <2>; }; Signed-off-by: Yuriy Kolerov <yuriy.kolerov@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
