Here is the big set of USB and Thunderbolt changes for 6.9-rc1. Lots of
tiny changes and forward progress to support new hardware and better
support for existing devices. Included in here are:
- Thunderbolt (i.e. USB4) updates for newer hardware and uses as more
people start to use the hardware
- default USB authentication mode Kconfig and documentation update to
make it more obvious what is going on
- USB typec updates and enhancements
- usual dwc3 driver updates
- usual xhci driver updates
- function USB (i.e. gadget) driver updates and additions
- new device ids for lots of drivers
- loads of other small updates, full details in the shortlog
All of these, including a "last minute regression fix" have been in
linux-next with no reported issues.

This patch introduces a new API, tegra_xusb_padctl_get_port_number,
to the Tegra XUSB Pad Controller driver. This API is used to identify
the USB port that is associated with a given PHY.
The function takes a PHY pointer for either a USB2 PHY or USB3 PHY as input
and returns the corresponding port number. If the PHY pointer is invalid,
it returns -ENODEV.

Due to a long-standing issue in driver core, drivers may not probe defer
after having registered child devices to avoid triggering a probe
deferral loop (see fbc35b45f9f6 ("Add documentation on meaning of
-EPROBE_DEFER")).
Move registration of the typec switch to after looking up clocks and
other resources.
Note that PHY creation can in theory also trigger a probe deferral when
a 'phy' supply is used. This does not seem to affect the QMP PHY driver
but the PHY subsystem should be reworked to address this (i.e. by
separating initialisation and registration of the PHY).

The MSM8996 platform has registers setup different to the rest of QMP v3
USB platforms. It has PCS region at 0x600 and no PCS_MISC region, while
other platforms have PCS region at 0x800 and PCS_MISC at 0x600. This
results in the malfunctioning USB host on some of the platforms. The
commit f74c35b630d4 ("phy: qcom-qmp-usb: fix register offsets for
ipq8074/ipq6018") fixed the issue for IPQ platforms, but missed the
SDM845 which has the same register layout.
To simplify future platform addition and to make the driver more future
proof, rename qmp_usb_offsets_v3 to qmp_usb_offsets_v3_msm8996 (to mark
its peculiarity), rename qmp_usb_offsets_ipq8074 to qmp_usb_offsets_v3
and use it for SDM845 platform.

introduced register offsets to the driver but for ipq8074/ipq6018 they do
not match what was in the old style device tree. Example from old
ipq6018.dtsi:
<0x00078200 0x130>, /* Tx */
<0x00078400 0x200>, /* Rx */
<0x00078800 0x1f8>, /* PCS */
<0x00078600 0x044>; /* PCS misc */
which would translate to:
{.., .pcs = 0x800, .pcs_misc = 0x600, .tx = 0x200, .rx = 0x400 }
but was translated to:
{.., .pcs = 0x600, .tx = 0x200, .rx = 0x400 }
So split usb_offsets and fix USB initialization for IPQ8074 and IPQ6018.

The USB-C PHYs on the msm8998, QCM2290 and SM6115 platforms use special
register to control which lanes of the Type-C port are used for the
SuperSpeed USB connection. Mimic the qmp-combo driver and handle this
register.

Now as all dual-lane PHYs have been migrated to a new driver, drop
support for dual lanes configuration. If the PHY uses two lanes for USB,
it is symthom that it should use either a combo USB+DP or a USB-C PHY
driver.

In preparation to adding Type-C handling for MSM8998, QCM2290 and SM6115
platforms, create new QMP USB-C PHY driver by splitting mentioned
platforms to a separate file. In future it will also be extended with
support for the DisplayPort handling. It will also be reused later for
such platforms as SDM660, SM6125, SM6150.

On SM8550, two sets of UFS PHY settings are provided, one set is to support
HS-G5, another set is to support HS-G4 and lower gears. The two sets of PHY
settings are programming different values to different registers, mixing
the two sets and/or overwriting one set with another set is definitely not
blessed by UFS PHY designers.
To add HS-G5 support for SM8550, split the two sets of PHY settings into
their dedicated overlay tables, only the common parts of the two sets of
PHY settings are left in the .tbls.
Consider we are going to add even higher gear support in future, to avoid
adding more tables with different names, rename the .tbls_hs_g4 and make it
an array, a size of 2 is enough as of now.
In this case, .tbls alone is not a complete set of PHY settings, so either
tbls_hs_overlay[0] or tbls_hs_overlay[1] must be applied on top of the
.tbls to become a complete set of PHY settings.

Pull drm updates from Dave Airlie:
"This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices,
it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more
upstream focused development model, and trying to maximise code
sharing. It's not enabled for any hw by default, and will hopefully
get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long
enough.
amdgpu has a bunch of new color management code that is being used in
the Steam Deck.
amdgpu also has a new ACPI WBRF interaction to help avoid radio
interference.
Otherwise it's the usual lots of changes in lots of places.
