From 59da381ee2afc806f85becf3aa64ffc952355552 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Wed, 31 Jul 2013 06:53:21 +0000 Subject: PCI: move enum pcie_link_width into pci.h pcie_link_width is the enum used to define the link width values for a pcie device. This enum should not be contained solely in pci_hotplug.h, and this patch moves it next to pci_bus_speed in pci.h Signed-off-by: Jacob Keller Tested-by: Phil Schmitt Acked-by: Bjorn Helgaas Signed-off-by: Jeff Kirsher --- include/linux/pci.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'include/linux/pci.h') diff --git a/include/linux/pci.h b/include/linux/pci.h index 0fd1f15..a0bf22d 100644 --- a/include/linux/pci.h +++ b/include/linux/pci.h @@ -183,6 +183,19 @@ enum pci_bus_flags { PCI_BUS_FLAGS_NO_MMRBC = (__force pci_bus_flags_t) 2, }; +/* These values come from the PCI Express Spec */ +enum pcie_link_width { + PCIE_LNK_WIDTH_RESRV = 0x00, + PCIE_LNK_X1 = 0x01, + PCIE_LNK_X2 = 0x02, + PCIE_LNK_X4 = 0x04, + PCIE_LNK_X8 = 0x08, + PCIE_LNK_X12 = 0x0C, + PCIE_LNK_X16 = 0x10, + PCIE_LNK_X32 = 0x20, + PCIE_LNK_WIDTH_UNKNOWN = 0xFF, +}; + /* Based on the PCI Hotplug Spec, but some values are made up by us */ enum pci_bus_speed { PCI_SPEED_33MHz = 0x00, -- cgit v1.1
