PCI: Move OF-related PCI functions into PCI core

2018-01-17T23:36:39Z

Following what has been done for other subsystems, move the remaining PCI related code out of drivers/of/ and into drivers/pci/of.c With this, we can kill a few kconfig symbols. Signed-off-by: Rob Herring [bhelgaas: minor whitespace, comment cleanups] Signed-off-by: Bjorn Helgaas Cc: Frank Rowand

of/pci: Fix theoretical NULL dereference

2017-11-16T17:01:14Z

In the (relatively mechanical) process of adapting the RID-mapping code to put the resulting ID in an output argument rather than the funtion return value, we ended up with the debug print using the argument pointer rather than the local value, which potentially defeats the earlier NULL check.

of_pci: use of_property_read_u32_array()

2017-07-24T15:00:52Z

of_pci_get_devfn() and of_pci_parse_bus_range() somehow didn't use of_property_read_u32_array() though it was long available, basically open-coding it. Using the modern DT API saves several bytes and also adds some prop sanity checks as a bonus... Signed-off-by: Sergei Shtylyov Signed-off-by: Rob Herring

of: Convert to using %pOF instead of full_name

2017-07-18T22:09:18Z

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. Signed-off-by: Rob Herring

of/pci: Remove unused MSI controller helpers

2017-03-14T20:10:11Z

All users of the small MSI controller API have been migrated to use the generic MSI infrastructure instead. We no longer need a global chained list of msi_controller. Instead, MSI controllers are now represented as IRQ domains attached to OF nodes, and the resolution between a device requesting an MSI and the corresponding MSI controller is done by the generic interrupt resolution logic. Therefore, this API is now completely useless, and can be removed from the kernel. Signed-off-by: Thomas Petazzoni Signed-off-by: Bjorn Helgaas Acked-by: Marc Zyngier Acked-by: Rob Herring

of/pci: Add of_pci_get_max_link_speed() to parse max-link-speed from DT

2016-11-14T21:21:14Z

This new helper function could be used by host drivers to get the limitaion of max link speed provided by DT. If the property isn't assigned or is invalid, it will return -EINVAL to the caller. Signed-off-by: Shawn Lin Signed-off-by: Bjorn Helgaas Acked-by: Rob Herring

of/irq: Break out msi-map lookup (again)

2016-09-16T08:34:14Z

The PCI msi-map code is already doing double-duty translating IDs and retrieving MSI parents, which unsurprisingly is the same functionality we need for the identically-formatted PCI iommu-map property. Drag the core parsing routine up yet another layer into the general OF-PCI code, and further generalise it for either kind of lookup in either flavour of map property.

of: use pr_fmt prefix for all console printing

2016-07-18T21:57:42Z

Clean-up all the DT printk functions to use common pr_fmt prefix. Some print statements such as kmalloc errors were redundant, so just drop those. Cc: Frank Rowand Cc: Pantelis Antoniou Reviewed-by: Frank Rowand Signed-off-by: Rob Herring

PCI: Remove includes of empty asm-generic/pci-bridge.h
