of/address: Constify of_busses[] array and pointers

2024-10-15T13:58:36Z

The of_busses array is fixed, so it and all struct of_bus pointers can be const. Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20241010-dt-const-v1-7-87a51f558425@kernel.org Signed-off-by: Rob Herring (Arm)

of: Constify struct device_node function arguments

2024-10-15T13:58:36Z

Functions which don't change the refcount or otherwise modify struct device_node can make struct device_node const. Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20241010-dt-const-v1-3-87a51f558425@kernel.org Signed-off-by: Rob Herring (Arm)

of/address: Add of_property_read_reg() helper

2023-04-13T22:46:35Z

Add a helper, of_property_read_reg(), to read "reg" entries untranslated address and size. This function is intended mainly for cases with an untranslatable "reg" address (i.e. not MMIO). There's also a few translatable cases such as address cells containing a bus chip-select number.

of/address: Add of_range_count() helper

2023-04-13T22:46:35Z

Some users need a count of the number of ranges entries before iterating over the entries. Typically this is for allocating some data structure based on the size. Add a helper, of_range_count(), to get the count. The helper must be called with an struct of_range_parser initialized by of_range_parser_init().

of/address: Add of_range_to_resource() helper

2023-04-13T22:46:35Z

A few users need to convert a specific "ranges" entry into a struct resource. Add a helper to similar to of_address_to_resource(). The existing of_pci_range_to_resource() helper isn't really PCI specific, so it can be used with the CONFIG_PCI check dropped.

of: Introduce of_translate_dma_region()

2023-01-25T10:48:27Z

This function is similar to of_translate_dma_address() but also reads a length in addition to an address from a device tree property. Reviewed-by: Rob Herring Signed-off-by: Thierry Reding Link: https://lore.kernel.org/r/20230120174251.4004100-2-thierry.reding@gmail.com Signed-off-by: Joerg Roedel

of: address: Use IS_ENABLED() for !CONFIG_PCI

2021-06-03T01:59:29Z

Convert address.c to use IS_ENABLED() instead of ifdefs for the public PCI functions. This simplifies the ifdefs in of_address.h. Cc: Frank Rowand Signed-off-by: Rob Herring Link: https://lore.kernel.org/r/20210527194547.1287934-4-robh@kernel.org

of: Merge of_get_address() and of_get_pci_address() implementations

2021-06-03T01:59:28Z

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

2020-07-28T20:49:52Z

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. Signed-off-by: Jiaxun Yang Reviewed-by: Rob Herring Signed-off-by: Thomas Bogendoerfer
