Sometimes CLKREQ# pin connection might be missing on a platform. Add DT
support to disable CLKREQ# control on PLLE in driver. Platform device tree
can use this DT property to disable CLKREQ# control on PLLE. In kernel-5.9,
upstream device tree property "supports-clkreq" is used in place of
kernel-4.14 custom device tree property "nvidia,disable-clock-request".

Programmed bits of register RP_VEND_XP_PAD_PWRDN are defined as follows,
L1(bit[0]):
This bit, when set, causes the analog pads to power down when we're in L1.
When clear, the LTSSM still enters L1 as required, but the analog pads
are left at full power.
DYNAMIC(bit[1]):
This bit, when set, causes unused analog pads to power down after
"Dynamic Link Width Re-negotiation" takes place. When clear, all analog
pads remain powered up, even those that are no longer being used after
"Dynamic Link Width Re-negotiation" down-sizes the link.
DISABLED(bit[2]):
This bit, when set, causes the analog pads to power down when we're in the
DISABLED_DOWN state. When clear, the LTSSM still enters DISBLED_DOWN as
required, but the analog pads are left at full power.
L1_CLKREQ(bit[15]):
This bit, when set, causes the analog pads to power down to
SLEEP_MODE_L1_REQ when clkreq signal is deasserted in L1.
(NV_PROJ__PCIE2_RP_VEND_XP_PAD_PWRDN_L1 needs to be set in order to power
down pad in L1.) Also, when clkreq is asserted in L1, ltssm will exit L1
immediately. When clear, the clkreq signal doesn't affect the power
management.
SLEEP_MODE_L1(bits[4:3]):
It defines the 2-bit sleep-mode coding in the pad when LTSSM is in the L1
state or DISABLED state.
SLEEP_MODE_DYNAMIC(bits[6:5]):
It defines the 2-bit sleep-mode coding in the pad when the lane shut down
due to dynamic link downsizing.
SLEEP_MODE_L1_CLKREQ(bits[17:16]):
It defines the 2-bit sleep-mode coding when clkreq is deasserted in L1.
The 2-bit sleep-mode encoding is defined as:
- L0 (0x0): Normal power-up mode
- L1 (0x1): L1 power-down mode; Tx common mode on, Rx e-idle detect on
- L1P (0x2): L1 power-down mode; Tx common mode off, Rx e-idle detect on
- L1PP (0x3): L1 power-down mode; Tx common mode off, Rx e-idle detect off

Few endpoints like Wi-Fi supports power on/off and to leverage that
root port must support hot-plug and hot-unplug. Tegra PCIe doesn't
support hot-plug and hot-unplug, however it supports endpoint power
on/off feature as follows,
- Power off sequence:
- Transition of PCIe link to L2
- Power off endpoint
- Leave root port in power up state with the link in L2
- Power on sequence:
- Power on endpoint
- Apply hot reset to get PCIe link up
PCIe client driver stops accessing PCIe endpoint config and BAR registers
after endpoint is powered off. However, software applications like x11
server or lspci can access endpoint config registers in which case
host controller raises "response decoding" errors. To avoid this scenario,
add PCIe link up check in config read and write callback functions before
accessing endpoint config registers.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Since 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are
used to identify modules. As a consequence, MODULE_LICENSE in non-modules
causes modprobe to misidentify the object file as a module when it is not,
and modprobe might succeed rather than failing with a suitable error
message.
For tristate modules that can be either built-in or loaded at runtime,
modprobe succeeds in both cases:
# modprobe ext4
[exit status zero if CONFIG_EXT4_FS=y or =m]
For boolean modules like the Standard Hot Plug Controller driver (shpchp)
that cannot be loaded at runtime, modprobe should always fail like this:
# modprobe shpchp
modprobe: FATAL: Module shpchp not found in directory /lib/modules/...
[exit status non-zero regardless of CONFIG_HOTPLUG_PCI_SHPC]
but prior to this commit, shpchp_core.c contained MODULE_LICENSE, so
"modprobe shpchp" silently succeeded when it should have failed.
Remove MODULE_LICENSE in files that cannot be built as modules.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
make more things static.
- Make portdrv bind to Switch Ports that have AER. Previously, if
these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
the Ports couldn't be suspended to low-power states. AER on these
Ports doesn't use interrupts, and the AER driver doesn't need to
claim them.
- Assign PCI domain IDs using ida_alloc(), which makes host bridge
add/remove work better.
Resource management:
- To work better with recent BIOSes that use EfiMemoryMappedIO for
PCI host bridge apertures, remove those regions from the E820 map
(E820 entries normally prevent us from allocating BARs). In v5.19,
we added some quirks to disable E820 checking, but that's not very
maintainable. EfiMemoryMappedIO means the OS needs to map the
region for use by EFI runtime services; it shouldn't prevent OS
from using it.
PCIe native device hotplug:
- Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
PCIe tunneling depends on native PCIe hotplug.
- Enable Command Completed Interrupt only if supported to avoid user
confusion from lspci output that says this is enabled but not
supported.
- Prevent pciehp from binding to Switch Upstream Ports; this happened
because of interaction with acpiphp and caused devices below the
Upstream Port to disappear.
Power management:
- Convert AGP drivers to generic power management. We hope to remove
legacy power management from the PCI core eventually.
Virtualization:
- Fix pci_device_is_present(), which previously always returned
"false" for VFs, causing virtio hangs when unbinding the driver.
Miscellaneous:
- Convert drivers to gpiod API to prepare for dropping some legacy
code.
- Fix DOE fencepost error for the maximum data object length.
Baikal-T1 PCIe controller driver:
- Add driver and DT bindings.
Broadcom STB PCIe controller driver:
- Enable Multi-MSI.
- Delay 100ms after PERST# deassert to allow power and clocks to
stabilize.
- Configure Read Completion Boundary to 64 bytes.
Freescale i.MX6 PCIe controller driver:
- Initialize PHY before deasserting core reset to fix a regression in
v6.0 on boards where the PHY provides the reference.
- Fix imx6sx and imx8mq clock names in DT schema.
Intel VMD host bridge driver:
- Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
SSDs in VT-d pass-through scenarios.
- Disable MSI remapping, which gets re-enabled by firmware during
suspend/resume.
MediaTek PCIe Gen3 controller driver:
- Add MT7986 and MT8195 support.
Qualcomm PCIe controller driver:
- Add SC8280XP/SA8540P basic interconnect support.
Rockchip DesignWare PCIe controller driver:
- Base DT schema on common Synopsys schema.
Synopsys DesignWare PCIe core:
- Collect DT items shared between Root Port and Endpoint (PERST GPIO,
PHY info, clocks, resets, link speed, number of lanes, number of
iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.
- Add dma-ranges support for Root Ports and Endpoints.
- Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
reduce code duplication.
- Add generic names for clocks and resets to encourage more
consistent naming across drivers using DesignWare IP.
- Stop advertising PTM Responder role for Endpoints, which aren't
allowed to be responders.
TI J721E PCIe driver:
- Add j721s2 host mode ID to DT schema.
- Add interrupt properties to DT schema.
Toshiba Visconti PCIe controller driver:
- Fix interrupts array max constraints in DT schema"

updated the Tegra PCI driver to use the macro PCI_CONF1_EXT_ADDRESS()
instead of a local function in the Tegra PCI driver. This broke PCI for
some Tegra platforms because, when calculating the offset value, the mask
applied to the lower 8-bits changed from 0xff to 0xfc.

While at it, convert the normal interrupt handler to a chained handler,
