Convert the fsl,layerscape-scfg binding to the new YAML format. In the device trees, the device node always have a "syscon" compatible, which wasn't mentioned in the previous binding. Also added, compared to the original binding, is the interrupt-controller subnode as used in arch/arm/boot/dts/ls1021a.dtsi as well as the litte-endian and big-endian properties. Signed-off-by:

Convert the fsl,ls-extirq binding to the new YAML format. In contrast to the original binding documentation, there are three compatibles which are used in their corresponding device trees which have a specific compatible and the (already documented) fallback compatible: - "fsl,ls1046a-extirq", "fsl,ls1043a-extirq" - "fsl,ls2080a-extirq", "fsl,ls1088a-extirq" - "fsl,lx2160a-extirq", "fsl,ls1088a-extirq" Depending on the number of the number of the external IRQs which is usually 12 except for the LS1021A where there are only 6, the interrupt-map-mask was reduced from 0xffffffff to 0xf and 0x7 respectively and the number of interrupt-map entries have to match.

Convert infracfg bindings to DT schema format. Not all drivers currently implement resets, so #reset-cells is made a required property only for those that do. Using power-controller in the example node name makes #power-domain-cells required causing a dt_binding_check error. To solve this, the node is renamed to syscon@10001000. Signed-off-by:

Let's add compatible for ti,am654-timer for TI am64, am65 and j72 SoCs. As the timer hardware is the same between am64, am65 and j72 we use the compatible name for the earliest SoC with this timer. The timer interrupts are not routable for the operating system for some timers on am6. Let's make sure the interrupts are configured for the timers on all other SoCs.

Let's update the TI timer binding to use yaml. As this binding is specific to the TI dual-mode timers also known as dm-timers, let's use file name ti,timer-dm.yaml to avoid confusion with other timers. We add checks for the deprecated ti,hwmods property as done for other TI device driver bindings earlier. We also correct the issue with the old binding that was out of date for several properties. The am43 related timers are undocumented, but compatible with the am3 timers. Let's add the am43 timers too. The dm814 and dm816 timers are missing, let's add them. Some timers on some SoCs are dual mapped, like the ABE timers on omap4 and 5. The reg property maxItems must be updated to 2. The timer clocks can be managed by the parent interconnect target module with no clocks assigned for the timer node. And in some cases, the SoC may need to configure additional system clock for the timer in addition to the functional clock. The clock names are optional and not specific to the comptible property. For example, dra7 timers on l3 interconnect do not need clock-names, while the timers on dra7 l4 interconnect need them with both being compatible with ti,omap5430-timer.

When the length of the string is zero of_property_read_string should return -ENODATA according to the description of the function. However, of_property_read_string doesn't check prop->length. If prop->length is zero, return -ENODATA. Without this patch the following command in u-boot: fdt set /chosen/node property-name results in of_property_read_string returning -EILSEQ when attempting to read property-name.

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.
