Changes from V5 to V6: - Patch [V4, 20/27]: Replaced pcie_pme_disable_msi() with no_msi quirk Changes from V4 to V5: - Patch [V4, 4/28]: Added blank line before block style comment - Patch [V4, 22/28]: "Access endpoint config only if PCIe link is up" patch is dropped - Patch [V4, 27/28]: * Updated reset gpio toggle logic to reflect active low usage * Replaced kasprintf() with devm_kasprintf() * Updated commit message with more information. Changes from V3 to V4: - Patch [V3,27/29] is dropped - Patch [V3,28/29]: devm_gpiod_get_from_of_node() is directly used in pci-tegra driver instead of of_get_pci* wrapper function defined in Patch [V3,27/29].
