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: Nicolas Saenz Julienne <nsaenzjulienne@suse.de> Reviewed-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de> Signed-off-by: Rob Herring <robh@kernel.org>
