    [NET] smc91x: Make smc91x use IRQ resource trigger flags · e7b3dc7e
    Russell King authored
    smc91x is shared between many different platforms.  Each platform needs
    to specify the interrupt type, and in some cases the irq type depends
    on more than just the build configuration - it depends on runtime
    checks.
    
    Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
    a way for these flags to be passed via the IRQ resource itself.
    
    Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
    with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
    the low bits of PCI iomem resources correspond with the BAR flag bits.
    
    Also provide a way to configure smc91x to read the IRQ flags from the
    resource.  Once all platforms have been converted over (signified
    by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
    be removed.
