The SBU and HSL orientation may be fixed/static from the mux
PoW. Apparently the retimer may take care of the orientation
of these lines. Handling the static SBU (AUX) and HSL
orientation with device properties.
If the SBU orientation is static, a device property
"sbu-orintation" can be used. When the property exists, the
driver always sets the SBU orientation according to the
property value, and when it's not set, the driver uses the
cable plug orientation with SBU.
And with static HSL orientation, "hsl-orientation" device
property can be used in the same way.

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

Currently UCSI framework doesn't update USB data role when partner type
is reported as power cable or power cable with ufp connected. This
results into no USB host mode functionality. This is valid usecase where
user wants to use legacy type c power cable with type a female connector
to attach different USB devices like mouse, thumb drive etc. Hence update
USB data role as host when partner type is reported as power cable or
power cable with ufp connected.

This converts the FUSB302 driver to use GPIO descriptors.
The conversion to descriptors per se is pretty straight-forward.
In the process I discovered that:
1. The driver uses a completely undocumented device tree binding
for the interrupt GPIO line, "fcs,int_n". Ooops.
2. The undocumented binding, presumably since it has not seen
review, is just "fcs,int_n", lacking the compulsory "-gpios"
suffix and also something that is not a good name because
the "_n" implies the line is inverted which is something we
handle with flags in the device tree. Ooops.
3. Possibly the driver should not be requesting the line as a
GPIO and request the corresponding interrupt line by open
coding, the GPIO chip is very likely doubleing as an IRQ
controller and can probably provide an interrupt directly
for this line with interrupts-extended = <&gpio0 ...>;
4. Possibly the IRQ should just be tagged on the I2C client node
in the device tree like apparently ACPI does, as it overrides
this IRQ with client->irq if that exists.
But now it is too late to do much about that and as I can see
this is used like this in the Pinebook which is a shipping product
so let'a just contain the mess and move on.
The property currently appears in:
arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts
Create a quirk in the GPIO OF library to allow this property
specifically to be specified without the "-gpios" suffix, we have
other such bindings already.

Since commit ef441dd6af ("usb: typec: mux: Allow the muxes to be named")
the typec_switch_desc and typec_mux_desc structs contain a name field.
The pi3usb30532 driver allocates these structs on the stack and so far did
not explicitly zero the mem used for the structs. This causes the new name
fields to point to a random memory address, which in my test case happens
to be a valid address leading to "interesting" mux / switch names:

NVIDIA VirtualLink (svid 0x955) has two altmode, vdo=0x1 for
VirtualLink DP mode and vdo=0x3 for NVIDIA test mode. NVIDIA
test device FTB (Function Test Board) reports altmode list with
vdo=0x3 first and then vdo=0x1. The list is:
SVID VDO
0xff01 0xc05
0x28de 0x8085
0x955 0x3
0x955 0x1
Current logic to assign mode value is based on order
in altmode list. This causes a mismatch of CON and SOP altmodes
since NVIDIA GPU connector has order of vdo=0x1 first and then
vdo=0x3. Fixing this by changing the order of vdo values
reported by NVIDIA test device. the new list will be:
SVID VDO
0xff01 0xc05
0x28de 0x8085
0x955 0x1085
0x955 0x3
Also NVIDIA VirtualLink (svid 0x955) uses pin E for display mode.
NVIDIA test device reports vdo of 0x1 so make sure vdo values
always have pin E assignement.

Even though originally the USB Type-C Specification did not
describe the steps for power role swapping without USB PD
contract in place, it did not actually mean power role swap
without USB PD was not allowed. The USB Type-C Specification
did not clearly separate the data and power roles until in
the release 1.2 which is why there also were no clear steps
for the scenario where only the power role was swapped
without USB PD contract before that.
Since in the latest version of the specification the power
role swap without USB PD is now clearly mentioned as allowed
operation, removing the check that prevented power role swap
without USB PD support.

The port_type attribute is special. It is meant to allow
changing the capability of the port in runtime. It is purely
Linux kernel specific feature, i.e. the feature is not
described in any of the USB specifications.
Because of the special nature of this attribute, handling it
differently compared to the other writable attributes, and
hiding it when the underlying port interface (or just the
driver) does not support the feature.

Here is the big USB and Thunderbolt and PHY driver updates for 5.6-rc1.
With the advent of USB4, "Thunderbolt" has really become USB4, so the
renaming of the Kconfig option and starting to share subsystem code has
begun, hence both subsystems coming in through the same tree here.
PHY driver updates also touched USB drivers, so that is coming in
through here as well.
Major stuff included in here are:
- USB 4 initial support added (i.e. Thunderbolt)
- musb driver updates
- USB gadget driver updates
- PHY driver updates
- USB PHY driver updates
- lots of USB serial stuff fixed up
- USB typec updates
- USB-IP fixes
- lots of other smaller USB driver updates
All of these have been in linux-next for a while now (the usb-serial
tree is already tested in linux-next on its own before merged into
here), with no reported issues.
