PCI: apple: Add initial hardware bring-upAdd a minimal driver to bring up the PCIe bus on Apple system-on-chips,particularly the Apple M1. This driver exposes the internal bus used forthe USB type-A ports, Ethernet, Wi-Fi, and Bluetooth.

f7821b49 - PCI: ixp4xx: Add a new driver for IXP4xx

Sun, 02 May 2021 22:09:20 +0000

PCI: ixp4xx: Add a new driver for IXP4xxThis adds a new PCI controller driver for the Intel IXP4xx(IX425, IXP435 etc), based on the XScale microarchitecture.This replaces the old driver in arch/arm/mach-ixp4xx/common-pci.cwhich utilized the ARM-specific BIOS32 PCI framework,and all parameterization for such things as memory andIO space as well as interrupt swizzling is done from thedevice tree.The plan is to phase out and delete the old driver piecemal.The __raw_writel() and __raw_readl() are used for accessingthe PCI controller for the same reason that these accessorsare used in the timer, IRQ and GPIO drivers: the platformwill alter its address bus pattern based on whether thesystem is booted in big- or little-endian mode. For thisreason all register on IXP4xx must always be accessed innative (CPU) endianness.This driver supports 64MB of PCI memory space, but not theindirect access of 1GB that is available in the old driver.We can address that later if and only if there are usersthat need all 1GB of PCI address space. Krzysztof reportshaving to use indirect MMIO only once for a VGA card. Thereis work ongoing for general indirect MMIO. (In practicethe indirect MMIO is performed by writing address andwriting and reading values into/from a controllerregister.)Tested by booting the NSLU2, attaching a USB stick, mountingand browsing the drive.Link: https://lore.kernel.org/linux-arm-kernel/m37edwuv8m.fsf@t19.piap.pl/Cc: Arnd Bergmann Cc: Imre Kaloz Cc: Krzysztof Halasa Cc: Zoltan HERPAI Cc: Raylynn Knight Acked-by: Bjorn Helgaas Reviewed-by: Arnd Bergmann Acked-by: Lorenzo Pieralisi Signed-off-by: Linus Walleij List of files: /linux-6.15/drivers/pci/controller/Makefile

6e5a1fff - PCI: Avoid building empty drivers

Mon, 08 Mar 2021 15:24:48 +0000

PCI: Avoid building empty driversThere are harmless warnings when compile testing the kernel withCONFIG_TRIM_UNUSED_KSYMS: drivers/pci/controller/dwc/pcie-al.o: no symbols drivers/pci/controller/pci-thunder-ecam.o: no symbols drivers/pci/controller/pci-thunder-pem.o: no symbolsThe problem here is that the host drivers get built even when theconfiguration symbols are all disabled, as they pretend to not be driversbut are silently enabled because of the promise that ACPI-based systemsneed no drivers.Add back the normal symbols to have these drivers built, and change thelogic to otherwise only build them when both CONFIG_PCI_QUIRKS andCONFIG_ACPI are enabled.As a side-effect, this enables compile-testing the drivers on otherarchitectures, which in turn needs the acpi_get_rc_resources() function tobe defined.Link: https://lore.kernel.org/r/20210308152501.2135937-3-arnd@kernel.orgSigned-off-by: Arnd Bergmann Signed-off-by: Bjorn Helgaas Reviewed-by: Robert Richter List of files: /linux-6.15/drivers/pci/controller/Makefile
