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.

Now that all the DT drivers have switched to platform_get_irq() we can now safely drop the static setup of IRQ resource from DT core code. With the above change hierarchical setup of irq domains is no longer bypassed and thus allowing hierarchical interrupt domains to describe interrupts using "interrupts" DT property. Signed-off-by:

Mention the usage of YAML coding style. Describe explicitly that four-space indentation in DTS examples is preferred, because: 1. The YAML's default two-space indentation for DTS code makes it significantly less readable. 2. Linux coding style tabs would introduce inconsistency (entire file is indented with spaces). 3. On the other hand, eight spaces would not align with example's opening ' - |' part. Four spaces makes the code nicely aligned with it. Signed-off-by:
