The altera driver only needs the device data, not the whole struct of_device_id. Use of_device_get_match_data() instead of of_match_device(). No functional change intended.

2021-11-18PCI: altera: Drop error data fabrication when config read failsNaveen Naidu1-3/+1
If config pci_ops.read() methods return failure, the PCI_OP_READ() and PCI_USER_READ_CONFIG() wrappers use PCI_SET_ERROR_RESPONSE() to set the data value, so there's no need to set it in the pci_ops.read() methods themselves. Drop the unnecessary data value fabrication when pci_ops.read() fails.

2020-08-04PCI: Set bridge map_irq and swizzle_irq to default functionsRob Herring1-2/+0
The majority of DT based host drivers use the default .map_irq() and .swizzle_irq() functions, so let's initialize the function pointers to the default and drop setting them in the host drivers. Drivers like iProc which don't support legacy interrupts need to set .map_irq() back to NULL.

2020-08-04PCI: Move DT resource setup into devm_pci_alloc_host_bridge()Rob Herring1-7/+0
Now that pci_parse_request_of_pci_ranges() callers just setup pci_host_bridge.windows and dma_ranges directly and don't need the bus range returned, we can just initialize them when allocating the pci_host_bridge struct. With this, pci_parse_request_of_pci_ranges() becomes a static function.

2020-08-03PCI: Remove dev_err() when handing an error from platform_get_irq()Krzysztof Wilczyński1-3/+1
There is no need to call the dev_err() function directly to print a custom message when handling an error from either the platform_get_irq() or platform_get_irq_byname() functions as both are going to display an appropriate error message in case of a failure. This change is as per suggestions from Coccinelle, e.g., drivers/pci/controller/dwc/pcie-armada8k.c:252:2-9: line 252 is redundant because platform_get_irq() already prints an error [bhelgaas: squashed into one commit] Suggested-by: Bjorn Helgaas <bhelgaas@google.com> Link: https://lore.kernel.org/r/20200802142601.1635926-2-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-3-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-4-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-5-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-6-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-7-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-8-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-9-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-10-kw@linux.com Link: https://lore.kernel.org/r/20200803071040.1663662-1-kw@linux.com Signed-off-by: Krzysztof Wilczyński <kw@linux.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Ley Foon Tan <ley.foon.tan@intel.com> # altera Acked-by: Jesper Nilsson <jesper.nilsson@axis.com> # dwc
2020-07-23PCI: Set default bridge parent deviceRob Herring1-1/+0
The host bridge's parent device is always the platform device. As we already have a pointer to it in the devres functions, let's initialize the parent device.

The altera host driver does the same host registration and bus scanning calls as pci_host_probe, so let's use it instead. The only difference is pci_assign_unassigned_bus_resources() was called instead of pci_bus_size_bridges() and pci_bus_assign_resources(). This should be the same.

Extend devm_of_pci_get_host_bridge_resources() and pci_parse_request_of_pci_ranges() helpers to also parse the inbound addresses from DT 'dma-ranges' and populate a resource list with the translated addresses.

2019-10-29PCI: altera: Use pci_parse_request_of_pci_ranges()Rob Herring1-39/+2
Convert altera host bridge to use the common pci_parse_request_of_pci_ranges(). There's no need to assign the resources to a temporary list first. Just use bridge->windows directly and remove all the temporary list handling. If an I/O range is present, then it will now be mapped. It's expected that h/w which doesn't support I/O range will not define one.

2019-06-17PCI: altera: Fix configuration type based on secondary numberLey Foon Tan1-14/+27
Stratix 10 PCIe controller does not support Type 1 to Type 0 conversion as previous version (V1) does so the PCIe controller configuration mechanism needs to send Type 0 config TLP if the target bus number matches with the secondary bus number. Implement a function to form a TLP header that depends on the PCIe controller version, so that the header can be formed according to specific host controller HW internals, fixing the type conversion issue.

2018-06-08PCI: Collect all native drivers under drivers/pci/controller/Shawn Lin1-0/+645
Native PCI drivers for root complex devices were originally all in drivers/pci/host/. Some of these devices can also be operated in endpoint mode. Drivers for endpoint mode didn't seem to fit in the "host" directory, so we put both the root complex and endpoint drivers in per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc. These per-device directories contain trivial Kconfig and Makefiles and clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and collect all the device-specific drivers there. No functional change intended.
