It allows CONFIG_OF to be enabled on x86 without a build failure. > The changelog says it's a stopgap measure - what exactly is the long > term plan and how long will it take? It is a stop gap because it performs a trivial direct map of an IRQ number in the device tree data structure to a Linux irq number. This works for a single IRQ controller, but falls apart when cascaded controller are described in the device tree. The long term plan is to have the drivers/of/ code handling the mapping intelligently like powerpc currently does. g. _______________________________________________ devicetree-discuss mailing list devicetree-discuss@lists.ozlabs.org https://lists.ozlabs.org/listinfo/devicetree-discuss
