Jason, Thomas, Here are further PCIe patches which follow on from the previous set of six I sent earlier in September. This set: * Separates the DT parsing from the use of this parsed data. * Fixes memory leaks from kasprintf() and refcount leaks of the DT node where we break out from the loop early. * Uses gpio_set_value_cansleep() so that GPIOs on I2C expanders can be used for the PCIe reset functionality. * Switch to using devm_kcalloc() instead of devm_kzalloc(), which eliminates the multiplication, moving it into core code. * Switch to using a gpio descriptor for the reset gpio, which can contain the active level information from DT. (It would be nice if gpiolib automated some of the resource claiming there.) * Make PERST# vs clock timing to match PCIe specifications. PCIe specs require the clock to be running for 100us prior to releasing reset. * Add the standard PCIe capability block in root port form to the emulated PCIe configuration block. This allows the PCI layer to identify the "host bridge" as a PCIe device, and allows us to take advantage of the code in drivers/pci/pcie, particularly aspm for link power management. * As a result of identifying ourselves as a PCIe root port, this eliminates the need to special case accesses to non-slot 0 in the driver; the lack of other "slots" is something which the generic PCI code knows about for PCIe root ports. drivers/pci/host/pci-mvebu.c | 404 ++++++++++++++++++++++++++++++++----------- 1 file changed, 305 insertions(+), 99 deletions(-) -- FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
