Hi, all I'm working on tegra wlan upstream issue. The tegra board use the Broadcom 4329 as wlan device, and the driver is the brcmfmac. This wlan driver support out-band-interrupt (OOB), I want to add DT support to use this OOB. I can add following lines in the dts file to create platform device and pass the interrupt resource to the driver. wlan { compatible = "broadcome, brcmf_sdio_pd"; interrupt-parten = <&gpio>; interrupts = <144, 0x04>; /* IRQF_TRIGGER_HIGH */ }; In the wlan driver, it will use platform_get_resource() to get the res->irq, res->flags, the irq number is right, but the flags will be IORESOURCE_IRQ, not the 0x04 (IRQF_TRIGGER_HIGH). The wlan driver wish this flags include the IRQF_TRGGER_* information, and it will use this flags to configure other hw settings. If it is wrong, the wlan can't work. I checked drivers/of/irq.c, in function of_irq_to_resource(), it will set r->flags = IORESOURCE_IRQ directly, not read the flags from the dtb file. And I didn't find any of_xx api to get this flags. How can I get this flags, does anyone has suggestion? Thanks.
