PCI: altera: Prefer of_device_get_match_data()

2022-01-03T21:00:47+00:00

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.

PCI: altera: Drop error data fabrication when config read fails

2021-11-18T19:41:07+00:00

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.

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq().

PCI: Set bridge map_irq and swizzle_irq to default functions

2020-08-04T15:36:30+00:00

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.

PCI: Move DT resource setup into devm_pci_alloc_host_bridge()

2020-08-04T15:36:30+00:00

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.

PCI: Remove dev_err() when handing an error from platform_get_irq()

2020-08-03T14:26:03+00:00

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 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 Signed-off-by: Bjorn Helgaas Reviewed-by: Ley Foon Tan # altera Acked-by: Jesper Nilsson # dwc

PCI: Set default bridge parent device

2020-07-23T10:20:49+00:00

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. Drivers can still override the parent if desired.
