Since the "dma-ranges" property is only valid for a node representing a bus, of_dma_get_range() currently assumes the node passed in is a leaf representing a device, and starts the walk from its parent. In cases like PCI host controllers on typical FDT systems, however, where the PCI endpoints are probed dynamically the initial leaf node represents the 'bus' itself, and this logic means we fail to consider any "dma-ranges" describing the host bridge itself. Rework the logic such that of_dma_get_range() also works correctly starting from a bus node containing "dma-ranges". While this does mean "dma-ranges" could incorrectly be in a device leaf node, there isn't really any way in this function to ensure that a leaf node is or isn't a bus node. Signed-off-by:

of_pci_range_parser_one() has a bug when parsing dma-ranges. When it translates the parent address (aka cpu address in the code), 'ranges' is always being used. This happens to work because most users are just 1:1 translation. Cc: Robin Murphy <robin.murphy@arm.com> Tested-by:

'dma-ranges' frequently exists without parent nodes having 'dma-ranges'. While this is an error for 'ranges', this is fine because DMA capable devices always have a translatable DMA address. Also, with no 'dma-ranges' at all, the assumption is that DMA addresses are 1:1 with no restrictions unless perhaps the device itself has implicit restrictions.

The functions for parsing 'dma-ranges' ranges are buggy and fail to handle several conditions. Add new tests for of_dma_get_range() and for_each_of_pci_range(). With this test, we get 5 new failures which are fixed in subsequent commits: OF: translation of DMA address(0) to CPU address failed node(/testcase-data/address-tests/device@70000000) FAIL of_unittest_dma_ranges_one():798 of_dma_get_range failed on node /testcase-data/address-tests/device@70000000 rc=-22 OF: translation of DMA address(10000000) to CPU address failed node(/testcase-data/address-tests/bus@80000000/device@1000) FAIL of_unittest_dma_ranges_one():798 of_dma_get_range failed on node /testcase-data/address-tests/bus@80000000/device@1000 rc=-22 OF: translation of DMA address(0) to CPU address failed node(/testcase-data/address-tests/pci@90000000) FAIL of_unittest_dma_ranges_one():798 of_dma_get_range failed on node /testcase-data/address-tests/pci@90000000 rc=-22 FAIL of_unittest_pci_dma_ranges():851 for_each_of_pci_range wrong CPU addr (d0000000) on node /testcase-data/address-tests/pci@90000000 FAIL of_unittest_pci_dma_ranges():861 for_each_of_pci_range wrong CPU addr (ffffffffffffffff) on node /testcase-data/address-tests/pci@90000000 Cc: Robin Murphy <robin.murphy@arm.com> Tested-by:

In some cases such as PCI host controllers, we may have a "parent bus" which is an OF leaf node, but still need to correctly parse ranges from the point of view of that bus. For that, factor out variants of the "#addr-cells" and "#size-cells" parsers which do not assume they have a device node and thus immediately traverse upwards before reading the relevant property.

Much like for address translation, when checking for DMA coherence we should be sure to walk up the DMA hierarchy, rather than the MMIO one, now that we can accommodate them being different. Signed-off-by:

The binding has a typo where resets-names should read reset-names, which in turn leads to a warning when the example is validated, since reset-names is being used, and the binding prevent the usage of any property that isn't described.

The example contains an SPI bus and device, but doesn't have the appropriate size and address cells size. This creates a DTC warning when the example is compiled since the default ones will not match what the device uses. Let's add them to remove that warning.

The AD7192 binding describes two regulator properties, avdd-supply and dvdd-supply, but describes it as a constant string that must be avdd and dvdd. This is wrong since a *-supply property is actually a phandle, and results in warnings when the example is validated (or any device tree using that device, for that matter). Let's remove that requirement. Fixes: f7356e47 ("dt-bindings: iio: adc: ad7192: Add binding documentation for AD7192") Signed-off-by:
