      of/irq: Use interrupts-extended to find parent · e9103362
      Samuel Holland authored
      The RISC-V PLIC binding uses interrupts-extended to specify its parent
      domain(s). That binding does not allow the interrupt-parent property to
      appear in the irqchip node. This prevents of_irq_init from properly
      detecting the irqchip hierarchy.
      
      If no interrupt-parent property is present in the enclosing bus or root
      node, then desc->interrupt_parent will be NULL for both the per-CPU
      RISC-V INTC (the actual root domain) and the RISC-V PLIC. Similarly, if
      the bus or root node specifies `interrupt-parent = <&plic>`, then
      of_irq_init will hit the `desc->interrupt_parent == np` check, and again
      all parents will be NULL. So things happen to work today for some boards
      due to Makefile ordering.
      
      However, things break when another irqchip ("foo") is stacked on top of
      the PLIC. The bus or root node will have `interrupt-parent = <&foo>`,
      since that is what all of the other peripherals need. When of_irq_init
      runs, it will try to find the PLIC's parent domain. of_irq_find_parent
      will fall back to using the interrupt-parent property of the PLIC's
      parent node (i.e. the bus or root node), and of_irq_init will see "foo"
      as the PLIC's parent domain. But this is wrong, because "foo" is
      actually the PLIC's child domain!
      
      So of_irq_init wrongly attempts to init the stacked irqchip before the
      PLIC. This fails and breaks booting.
      
      Fix this by using the first node referenced by interrupts-extended as
      the parent when that property is present. This allows of_irq_init to see
      the relationship between the PLIC and the per-CPU RISC-V INTC, and thus
      only the RISC-V INTC is (correctly) considered a root domain.

      This log message was accidentally chopped off.
      
      I was wondering why this happened, but checking the ML log, Mark
      precisely followed my suggestion [1].
      
      I just used "..." because I was too lazy to type the sentence fully.
      Sorry for the confusion.
