of: Introduce of_translate_dma_region()

2023-01-25T10:48:27+00:00

This function is similar to of_translate_dma_address() but also reads a
length in addition to an address from a device tree property.

of/address: introduce of_address_count() helper

2022-10-16T22:58:54+00:00

Introduce of_address_count() helper to count the IO resources
instead of open-coding it.

of: address: Use IS_ENABLED() for !CONFIG_PCI

2021-06-03T01:59:29+00:00

Convert address.c to use IS_ENABLED() instead of ifdefs for the
public PCI functions. This simplifies the ifdefs in of_address.h.

of: Merge of_get_address() and of_get_pci_address() implementations

2021-06-03T01:59:28+00:00

of_get_address() and of_get_pci_address() are the same implementation
except of_get_pci_address() takes the PCI BAR number rather than an
index. Modify the of_get_address() implementation to work on either
index or BAR and provide wrapper functions for the existing functions.

of_address: Add bus type match for pci ranges parser

2020-07-28T20:49:52+00:00

So the parser can be used to parse range property of ISA bus.

As they're all using PCI-like method of range property, there is no need
start a new parser.

of/address: Rework of_pci_range parsing for non-PCI buses

2020-02-14T20:25:26+00:00

The only PCI specific part of of_pci_range_parser_one() is the handling
of the 3rd address cell. Rework it to work on regular 1 and 2 cell
addresses.

Use defines and a union to avoid a treewide renaming of the parsing
helpers and struct.

of: Drop struct of_pci_range.pci_space field

2020-02-14T20:25:25+00:00

There's no more users of struct of_pci_range.pci_space field, so remove it.

of/address: Fix of_pci_range_parser_one translation of DMA addresses

2019-10-08T18:55:26+00:00

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.

of: Make of_dma_get_range() private

2019-10-08T18:50:22+00:00

of_dma_get_range() is only used within the DT core code, so remove the
export and move the header declaration to the private header.
