2018-09-27apalis-tk1: improve pcie reset for reliable gigabit ethernet operationMarcel Ziswiler
While the PCIe reset implementation seems to work it currently resets multiple times due to not differentiating which PCIe port needs resetting. Improve this by doing specific reset per port only.

2017-09-20apalis-tk1: fix pcie reset for reliable gigabit ethernet operationMarcel Ziswiler
It turns out that the current PCIe reset implementation is not quite working reliably due to some Intel i210 errata. Fix this by making sure the i210's +V3.3_ETH rail is properly disabled during its reset sequence. Also further improve on the bringing up the PCIe switch as found on the Apalis Evaluation board.

2014-03-23PCI: Enable INTx in pci_reenable_device() only when MSI/MSI-X not enabledBjorn Helgaas
commit 3cdeb713dc66057b50682048c151eae07b186c42 upstream. Andreas reported that after 1f42db786b14 ("PCI: Enable INTx if BIOS left them disabled"), pciehp surprise removal stopped working. This happens because pci_reenable_device() on the hotplug bridge (used in the pciehp_configure_device() path) clears the Interrupt Disable bit, which apparently breaks the bridge's MSI hotplug event reporting. Previously we cleared the Interrupt Disable bit in do_pci_enable_device(), which is used by both pci_enable_device() and pci_reenable_device(). But we use pci_reenable_device() after the driver may have enabled MSI or MSI-X, and we *set* Interrupt Disable as part of enabling MSI/MSI-X. This patch clears Interrupt Disable only when MSI/MSI-X has not been enabled.

commit 1f42db786b14a31bf807fc41ee5583a00c08fcb1 upstream. Some firmware leaves the Interrupt Disable bit set even if the device uses INTx interrupts. Clear Interrupt Disable so we get those interrupts. Based on the report mentioned below, if the user selects the "EHCI only" option in the Intel Baytrail BIOS, the EHCI device is handed off to the OS with the PCI_COMMAND_INTX_DISABLE bit set.
