PCI: Explicitly include correct DT includes

2023-07-18T19:33:17+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

PCI: Use consistent controller Kconfig menu entry language

2023-04-20T21:18:04+00:00

Use "PCIe controller" consistently instead of "host bridge", "bus driver", etc. Annotate with "(host mode)" or "(endpoint mode)" as needed. Link: https://lore.kernel.org/r/20230418174336.145585-5-helgaas@kernel.org Signed-off-by: Bjorn Helgaas

PCI: Remove MODULE_LICENSE so boolean drivers don't look like modules

2023-02-17T14:47:58+00:00

Since 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, MODULE_LICENSE in non-modules causes modprobe to misidentify the object file as a module when it is not, and modprobe might succeed rather than failing with a suitable error message. For tristate modules that can be either built-in or loaded at runtime, modprobe succeeds in both cases: # modprobe ext4 [exit status zero if CONFIG_EXT4_FS=y or =m] For boolean modules like the Standard Hot Plug Controller driver (shpchp) that cannot be loaded at runtime, modprobe should always fail like this: # modprobe shpchp modprobe: FATAL: Module shpchp not found in directory /lib/modules/... [exit status non-zero regardless of CONFIG_HOTPLUG_PCI_SHPC] but prior to this commit, shpchp_core.c contained MODULE_LICENSE, so "modprobe shpchp" silently succeeded when it should have failed. Remove MODULE_LICENSE in files that cannot be built as modules.

PCI/MSI: Get rid of PCI_MSI_IRQ_DOMAIN

2022-11-17T14:15:19+00:00

What a zoo: PCI_MSI select GENERIC_MSI_IRQ PCI_MSI_IRQ_DOMAIN def_bool y depends on PCI_MSI select GENERIC_MSI_IRQ_DOMAIN Ergo PCI_MSI enables PCI_MSI_IRQ_DOMAIN which in turn selects GENERIC_MSI_IRQ_DOMAIN. So all the dependencies on PCI_MSI_IRQ_DOMAIN are just an indirection to PCI_MSI. Match the reality and just admit that PCI_MSI requires GENERIC_MSI_IRQ_DOMAIN.

PCI: mobiveil: Remove unused readl and writel functions

2021-06-03T16:13:55+00:00

The PCIe host controller driver for Layerscape 4th generation SoC was added in the commit d29ad70a813b ("PCI: mobiveil: Add PCIe Gen4 RC driver for Layerscape SoCs"). At this time two static functions were introduced that appear to currently have no users. Since nothing is using neither of these functions at the moment they can be safely removed. This resolves the following build time warnings: drivers/pci/controller/mobiveil/pcie-layerscape-gen4.c:45:19: warning: unused function 'ls_pcie_g4_lut_readl' [-Wunused-function] drivers/pci/controller/mobiveil/pcie-layerscape-gen4.c:50:20: warning: unused function 'ls_pcie_g4_lut_writel' [-Wunused-function] Link: https://lore.kernel.org/r/20210510023032.3063932-1-kw@linux.com Signed-off-by: Krzysztof Wilczyński Signed-off-by: Lorenzo Pieralisi

PCI: mobiveil: Improve PCIE_LAYERSCAPE_GEN4 dependencies

2021-03-23T10:29:24+00:00

- Drop the dependency on PCI, as this is implied by the dependency on PCI_MSI_IRQ_DOMAIN, - Drop the dependencies on OF and ARM64, as the driver compiles fine without OF and/or on other architectures, - The Freescale Layerscape PCIe Gen4 controller is present only on Freescale Layerscape SoCs. Hence depend on ARCH_LAYERSCAPE, to prevent asking the user about this driver when configuring a kernel without Freescale Layerscape support, unless compile-testing.
