* MIPS: PCI: fix pcibios_map_irq section mismatchManuel Lauss2017-09-211-1/+1
| | | | | | | | | | | | | | | | | | Drop the __init from pcibios_map_irq() to make this section mis- match go away: WARNING: vmlinux.o(.text+0x56acd4): Section mismatch in reference from the function pcibios_scanbus() to the function .init.text:pcibios_map_irq() The function pcibios_scanbus() references the function __init pcibios_map_irq(). This is often because pcibios_scanbus lacks a __init annotation or the annotation of pcibios_map_irq is wrong. Run-Tested only on Alchemy.

* MIPS: Convert to using %pOF instead of full_nameRob Herring2017-08-291-6/+5
| | | | | | | | | | | | | Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

* MIPS: pci: Audit and remove any unnecessary uses of module.hPaul Gortmaker2016-10-051-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. The advantage in doing so is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h was the source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each obj-y/bool instance for the presence of either and replace as needed. We also needed to remove the no-op MODULE_DEVICE_TABLE usage in several instances to permit removal of the module.h include. The files in these instances were all controlled by bool Kconfig. In one instance, module_param was being used so we transition the module.h include onto a moduleparam.h include.

* genirq: Remove irq argument from irq flow handlersThomas Gleixner2015-09-161-1/+1
| | | | | | | | | | | | | | Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument.

* of/irq: Rename of_irq_map_* functions to of_irq_parse_*Grant Likely2013-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | The OF irq handling code has been overloading the term 'map' to refer to both parsing the data in the device tree and mapping it to the internal linux irq system. This is probably because the device tree does have the concept of an 'interrupt-map' function for translating interrupt references from one node to another, but 'map' is still confusing when the primary purpose of some of the functions are to parse the DT data. This patch renames all the of_irq_map_* functions to of_irq_parse_* which makes it clear that there is a difference between the parsing phase and the mapping phase. Kernel code can make use of just the parsing or just the mapping support as needed by the subsystem. The patch was generated mechanically with a handful of sed commands.

* MIPS: Add driver for the built-in PCI controller of the RT3883 SoCGabor Juhos2013-09-041-0/+636
The Ralink RT3883 SoCs have a built-in PCI Host Controller device. The patch adds a platform driver and device tree binding documentation for that. The patch also enables the HW_HAS_PCI config option. This is required in order to be able to enable the PCI support.
