From 7508320678b7819ac6aeb89580b8622a424ce586 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 5 Dec 2012 13:51:19 -0700 Subject: PCI: Add standard PCIe Capability Link ASPM field names Add standard #defines for ASPM fields in PCI Express Link Capability and Link Control registers. Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but these are defined for the Linux ASPM interfaces, e.g., pci_disable_link_state(), and only coincidentally match the actual register bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match the register bit.
