Convert the fsl,layerscape-dcfg 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. One thing added here, compared to the original binding is the clock controller subnode of the LS1028A SoC and its "simple-mfd" compatible as used in arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi as well as the little-endian and big-endian properties.

Fix various kfree() issues related to of_overlay_apply(). - Double kfree() of fdt and tree when init_overlay_changeset() returns an error. - free_overlay_changeset() free the root of the unflattened overlay (variable tree) instead of the memory that contains the unflattened overlay. - For the case of a failure during applying an overlay, move kfree() of new_fdt and overlay_mem into free_overlay_changeset(), which is called by the function that allocated them. - For the case of removing an overlay, the kfree() of new_fdt and overlay_mem remains in free_overlay_changeset(). - Check return value of of_fdt_unflatten_tree() for error instead of checking the returned value of overlay_root. - When storing pointers to allocated objects in ovcs, do so as near to the allocation as possible instead of in deeply layered function. More clearly document policy related to lifetime of pointers into overlay memory. Double kfree() Reported-by:Slawomir Stepien <slawomir.stepien@nokia.com> Signed-off-by:

Variables change name across function calls when there is not a good reason to do so. Fix by changing "fdt" to "new_fdt" and "tree" to "overlay_root". The name disparity was confusing when creating the following commit. The name changes are in this separate commit to make review of the following commmit less complex. Signed-off-by:

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. With this patch, it returns -ENODATA as expected. Signed-off-by:

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.

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:
