PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1

PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1

commit b1049f2d68693c80a576c4578d96774a68df2bad upstream.

commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets the
policy that all PCIe ports are allowed to use D3. When the system is
suspended if the port is not power manageable by the platform and won't be
used for wakeup via a PME this sets up the policy for these ports to go
into D3hot.

This policy generally makes sense from an OSPM perspective but it leads to
problems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with a
specific old BIOS. This manifests as a system hang.

On the affected Device + BIOS combination, add a quirk for the root port of
the problematic controller to ensure that these root ports are not put into
D3hot at suspend.

This patch is based on

https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.com

but with the added condition both in the documentation and in the code to
apply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and only
the affected root ports.

x86/PCI: Check pcie_find_root_port() return for NULL

If pcie_find_root_port() is unable to locate a Root Port, it will return
NULL. Check the pointer for NULL before dereferencing it.

This particular case is in a quirk for devices that are always below a Root
Port, so this won't avoid a problem and doesn't need to be backported, but
check as a matter of style and to prevent copy/paste mistakes.

PCI: Disable D3cold on Asus B1400 PCI-NVMe bridge

[ Upstream commit cdea98bf1faef23166262825ce44648be6ebff42 ]

The Asus B1400 with original shipped firmware versions and VMD disabled
cannot resume from suspend: the NVMe device becomes unresponsive and
inaccessible.

This appears to be an untested D3cold transition by the vendor; Intel
socwatch shows that Windows leaves the NVMe device and parent bridge in D0
during suspend, even though these firmware versions have StorageD3Enable=1.

The NVMe device and parent PCI bridge both share the same "PXP" ACPI power
resource, which gets turned off as both devices are put into D3cold during
suspend. The _OFF() method calls DL23() which sets a L23E bit at offset
0xe2 into the PCI configuration space for this root port. This is the
specific write that the _ON() routine is unable to recover from. This
register is not documented in the public chipset datasheet.

Disallow D3cold on the PCI bridge to enable successful suspend/resume.

x86/PCI: Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4

commit 7d08f21f8c6307cb05cabb8d86e90ff6ccba57e9 upstream.

Iain reports that USB devices can't be used to wake a Lenovo Z13 from
suspend. This occurs because on some AMD platforms, even though the Root
Ports advertise PME_Support for D3hot and D3cold, wakeup events from
devices on a USB4 controller don't result in wakeup interrupts from the
Root Port when amd-pmc has put the platform in a hardware sleep state.

If amd-pmc will be involved in the suspend, remove D3hot and D3cold from
the PME_Support mask of Root Ports above USB4 controllers so we avoid those
states if we need wakeups.

Restore D3 support at resume so that it can be used by runtime suspend.

This affects both AMD Rembrandt and Phoenix SoCs.

"pm_suspend_target_state == PM_SUSPEND_ON" means we're doing runtime
suspend, and amd-pmc will not be involved. In that case PMEs work as
advertised in D3hot/D3cold, so we don't need to do anything.

Note that amd-pmc is technically optional, and there's no need for this
quirk if it's not present, but we assume it's always present because power
consumption is so high without it.
