Register mode switch devices for Type-C connectors, when they are
specified by firmware. These control Type-C configuration for any USB
Type-C mode switches (sometimes known as "muxes") which are controlled
by the ChromeOS EC.

The ChromeOS EC updates Type-C status events when mux set requests from
the Application Processor (AP) are completed. Add a check to the
flow of configuring muxes to look for this status done bit, so that
the driver is aware that the mux set completed successfully or not.

Introduce a driver to configure USB Type-C mode switches and retimers
which are controlled by the ChromeOS EC (Embedded Controller).
This allows Type-C port drivers, as well as alternate mode drivers to
configure their relevant mode switches and retimers according to the
Type-C state they want to achieve.
ACPI devices with ID GOOG001A will bind to this driver.
Currently, we only register a retimer switch with a stub set function.
Subsequent patches will implement the host command set functionality,
and introduce mode switches.

When the cable is unplugged, the Atheros AR803x PHYs will enter
hibernation mode after about 10 seconds if the hibernation mode
is enabled and will not provide any clock to the MAC. But for
some MACs, this feature might cause unexpected issues due to the
logic of MACs.
Taking SYNP MAC (stmmac) as an example, if the cable is unplugged
and the "eth0" interface is down, the AR803x PHY will enter
hibernation mode. Then perform the "ifconfig eth0 up" operation,
the stmmac can't be able to complete the software reset operation
and fail to init it's own DMA. Therefore, the "eth0" interface is
failed to ifconfig up. Why does it cause this issue? The truth is
that the software reset operation of the stmmac is designed to
depend on the RX_CLK of PHY.
So, this patch offers an option for the user to determine whether
to disable the hibernation mode of AR803x PHYs.

Fix incorrect pin assignment values when connecting to a monitor with
Type-C receptacle instead of a plug.
According to specification, an UFP_D receptacle's pin assignment
should came from the UFP_D pin assignments field (bit 23:16), while
an UFP_D plug's assignments are described in the DFP_D pin assignments
(bit 15:8) during Mode Discovery.
For example the LG 27 UL850-W is a monitor with Type-C receptacle.
The monitor responds to MODE DISCOVERY command with following
DisplayPort Capability flag:
dp->alt->vdo=0x140045
The existing logic only take cares of UPF_D plug case,
and would take the bit 15:8 for this 0x140045 case.
This results in an non-existing pin assignment 0x0 in
dp_altmode_configure.
To fix this problem a new set of macros are introduced
to take plug/receptacle differences into consideration.

Commit 451ef36bd229 ("ip_tunnels: Add new flow flags field to ip_tunnel_key")
added a "flow_flags" member to struct ip_tunnel_key which was later used by
the commit in the fixes tag to avoid dropping packets with sources that
aren't locally configured when set in bpf_set_tunnel_key().
VXLAN and GENEVE were made to respect this flag, ip tunnels like IPIP and GRE
were not.
This commit fixes this omission by making ip_tunnel_init_flow() receive
the flow flags from the tunnel key in the relevant collect_md paths.

The SDM845 comes with few instances of Bandwidth Monitor. The already
supported one monitors traffic between CPU and Last Level Cache
Controller (LLCC) and in downstream sources is called BWMON v4 (or v4 of
register layout).
SDM845 also has also BWMON instance measuring traffic between LLCC and
memory with different register layout: called v5.
Add support for this "LLCC" BWMON. Differences against existing v4 one:
1. No global interrupts.
2. Different register layout.
3. Different shift of interrupt fields.
4. Smaller sampling window.

Refactor the code to prepare it for supporting BWMON v5 which comes with
different register layout by:
1. Adding use of MMIO regmap and regmap fields which allows to keep one
code logic with different register maps.
2. The "clear" type registers do not allow reading, therefore regmap
requires using cache with default values.
3. regmap has an effect of introducing barriers after each readl/writel,
which should negligible effect as only few writes were relaxed.
4. Additionally usage of regmap fields removes need of shifting the
register values.
5. Add "V4" prefix to names of all defines with register addresses (so
BWMON_V4_xxx) to differentiate it from V5. The actual register values
are shared so keep their naming.
6. While changing the defines, pad register addresses to three digits
for readability.

Instead of copying pieces of variant-specific data (struct
icc_bwmon_data) into the state container (struct icc_bwmon), just store
a pointer to it.
This simplifies a bit the code and allows later to grow easily the

reset of the hub. There is already a delay in onboard_hub_power_on()
before de-asserting the reset, which ensures that the reset is
asserted for the required time, so the delay in _power_off() is not
needed.

This adds the necessary ACPI ID for Intel Meteor Lake
IOM devices.
The callback function is_memory() is modified so that it
also checks if the resource descriptor passed to it is a
memory type "Address Space Resource Descriptor".
On Intel Meteor Lake the ACPI memory resource is not
described using the "32-bit Memory Range Descriptor" because
the memory is outside of the 32-bit address space. The
memory resource is described using the "Address Space
Resource Descriptor" instead.
Intel Meteor Lake is the first platform to describe the
memory resource for this device with Address Space Resource
Descriptor, but it most likely will not be the last.
Therefore the change to the is_memory() callback function
is made generic.

This device does not remember its MAC address, so add a possibility
to get it from the platform. If it fails, generate a random address.
This will provide a MAC address early during boot without user space
being involved.
Also remove extra calls to is_valid_ether_addr().
Made after suggestions by Andrew Lunn:
1) Use eth_hw_addr_random() to assign a random MAC address during probe.
2) Remove is_valid_ether_addr() from moxart_mac_open()
3) Add a call to platform_get_ethdev_address() during probe
4) Remove is_valid_ether_addr() from moxart_set_mac_address(). The core does this
v1 -> v2:
Handle EPROBE_DEFER returned from platform_get_ethdev_address().
Move MAC reading code to the beginning of the probe function.

The commit c23d92b80e0b ("igb: Teardown SR-IOV before
unregister_netdev()") places the unregister_netdev() call after the
igb_disable_sriov() call to avoid functionality issue.
However, it introduces several race conditions when detaching a device.
For example, when .remove() is called, the below interleaving leads to
use-after-free.
(FREE from device detaching) | (USE from netdev core)
igb_remove | igb_ndo_get_vf_config
igb_disable_sriov | vf >= adapter->vfs_allocated_count?
kfree(adapter->vf_data) |
adapter->vfs_allocated_count = 0 |
| memcpy(... adapter->vf_data[vf]
Moreover, the igb_disable_sriov() also suffers from data race with the
requests from VF driver.
(FREE from device detaching) | (USE from requests)
igb_remove | igb_msix_other
igb_disable_sriov | igb_msg_task
kfree(adapter->vf_data) | vf < adapter->vfs_allocated_count
adapter->vfs_allocated_count = 0 |
To this end, this commit first eliminates the data races from netdev
core by using rtnl_lock (similar to commit 719479230893 ("dpaa2-eth: add
MAC/PHY support through phylink")). And then adds a spinlock to
eliminate races from driver requests. (similar to commit 1e53834ce541

Clean up the suspend callbacks by separating the error and success paths
to improve readability.
Also drop a related redundant initialisation.

It is the Qualcomm glue wakeup interrupts that may be able to wake the
system from suspend and this can now be described in the devicetree.
Move the wakeup-source property handling over from the core driver and
instead propagate the capability setting to the core device during
probe.
This is needed as there is currently no way for the core driver to query
the wakeup setting of the glue device, but it is the core driver that
manages the PHY power state during suspend.
Also don't leave the PHYs enabled when system wakeup has been disabled
through sysfs.

A recent commit implementing wakeup support in host mode instead broke
suspend for peripheral and OTG mode.
The hack that was added in the suspend path to determine the speed of
any device connected to the USB2 bus not only accesses internal driver
data for a child device, but also dereferences a NULL pointer or
accesses freed data when the controller is not acting as host.
There's no quick fix to the layering violation, but since reverting
would leave us with broken suspend in host mode with wakeup triggering
immediately, let's keep the hack for now.
Fix the immediate issues by only checking the host bus speed and
enabling wakeup interrupts when acting as host.

The Qualcomm dwc3 runtime-PM implementation checks the xhci
platform-device pointer in the wakeup-interrupt handler to determine
whether the controller is in host mode and if so triggers a resume.
After a role switch in OTG mode the xhci platform-device would have been
freed and the next wakeup from runtime suspend would access the freed
memory.
Note that role switching is executed from a freezable workqueue, which
guarantees that the pointer is stable during suspend.
Also note that runtime PM has been broken since commit 2664deb09306
("usb: dwc3: qcom: Honor wakeup enabled/disabled state"), which
incidentally also prevents this issue from being triggered.

This reverts commit d9be8d5c5b032e5383ff5c404ff4155e9c705429.
Generic power-domain flags must be set before the power-domain is
initialised and must specifically not be modified by drivers for devices
that happen to be in the domain.
To make sure that USB power-domains are left enabled during system
suspend when a device in the domain is in the wakeup path, the
GENPD_FLAG_ACTIVE_WAKEUP flag should instead be set for the domain
unconditionally when it is registered.
Note that this also avoids keeping power-domains on during suspend when
wakeup has not been enabled (e.g. through sysfs).
For the runtime PM case, making sure that the PHYs are not suspended and
that they are in the same domain as the controller prevents the domain
from being suspended. If there are cases where this is not possible or
desirable, the genpd implementation may need to be extended.

Generic PHYs must be powered-off before they can be tore down.
Similarly, suspending legacy PHYs after having powered them off makes no
sense.
Fix the dwc3_core_exit() (e.g. called during suspend) and open-coded
dwc3_probe() error-path sequences that got this wrong.
Note that this makes dwc3_core_exit() match the dwc3_core_init() error
path with respect to powering off the PHYs.

Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove
paths") removed this clk_disable_unprepare()
This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock
handling on remove path") which removed this clk_disable_unprepare()
because:
"
While unloading the dwmac-intel driver, clk_disable_unprepare() is
being called twice in stmmac_dvr_remove() and
intel_eth_pci_remove(). This causes kernel panic on the second call.
"
However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management
for gmac driver") has updated stmmac_dvr_remove() which do not call
clk_disable_unprepare() anymore.
So this call should now be called from intel_eth_pci_remove().

Pages allocated with GFP_ATOMIC cannot come from Highmem. This is why
there is no need to call kmap() on them.
Therefore, don't call kmap() on rx_buffer->page() and instead use a
plain page_address() to get the kernel address.
