2019-10-14dt-bindings: Clean-up regulator '-supply' schemasRob Herring13-25/+5
Regulator '*-supply' properties are always a single phandle, so 'maxItems: 1' or a $ref is not necessary. All that's needed is either 'true' or an optional 'description'. Following this clean-up, the meta-schema will enforce this pattern. There's one case in tree with 'innolux,n156bge-l21' having 2 phandles. This appears to be a mistake or abuse of simple-panel as it's 2 different voltage rails connected to 'power-supply'.

2019-10-09of: Make of_dma_get_range() work on bus nodesRobin Murphy1-26/+18
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.

2019-10-08of/address: Fix of_pci_range_parser_one translation of DMA addressesRob Herring2-3/+13
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.

2019-10-08of/address: Translate 'dma-ranges' for parent nodes missing 'dma-ranges'Rob Herring1-1/+5
'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.

2019-10-08of: Factor out #{addr,size}-cells parsingRobin Murphy3-10/+27
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.
