PCI: OF: Add generic function to parse and allocate PCI resources

2018-01-31T11:09:32+00:00

The patch moves the gen_pci_parse_request_of_pci_ranges() function from drivers/pci/host/pci-host-common.c into drivers/pci/of.c to easily share common source code between PCI host drivers. Signed-off-by: Cyrille Pitchen Signed-off-by: Lorenzo Pieralisi

PCI: Add SPDX GPL-2.0+ to replace GPL v2 or later boilerplate

2018-01-28T21:49:06+00:00

Add SPDX GPL-2.0+ to all PCI files that specified the GPL and allowed either GPL version 2 or any later version. Remove the boilerplate GPL version 2 or later language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

PCI: Make of_irq_parse_pci() static

2018-01-25T14:48:20+00:00

Now that the DT PCI code is merged into drivers/pci, of_irq_parse_pci() can be static. Signed-off-by: Rob Herring Signed-off-by: Bjorn Helgaas Cc: Frank Rowand

PCI: Move OF-related PCI functions into PCI core

2018-01-17T23:36:39+00:00

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

PCI/MSI: Use of_msi_get_domain instead of open-coded "msi-parent" parsing

2015-10-16T12:07:14+00:00

Now that we have a function that implements the complexity of the "msi-parent" property parsing, switch to that. Acked-by: Rob Herring Acked-by: Bjorn Helgaas Signed-off-by: Marc Zyngier

PCI/MSI: Allow msi_domain lookup using the host bridge node

2015-07-29T22:14:37+00:00

A number of platforms do not need to use the msi-parent property, as the host bridge itself provides the MSI controller. Allow this configuration by performing an irq domain lookup based on the host bridge node if it doesn't have a valid msi-parent property.

PCI/MSI: Add support for OF-provided msi_domain

2015-07-29T22:14:37+00:00

In order to populate the PCI host bridge msi_domain, use the "msi-parent" attribute to lookup a corresponding irq domain. If found, this is our MSI domain. This gets plugged into the core PCI code.

PCI: OF: Don't crash when bridge parent is NULL.

2011-08-19T15:51:37+00:00

In pcibios_get_phb_of_node(), we will crash while booting if bus->bridge->parent is NULL. Check for this case and avoid dereferencing the NULL pointer. Signed-off-by: David Daney Acked-by: Benjamin Herrenschmidt Acked-by: Grant Likely Signed-off-by: Jesse Barnes
