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.

Instead of using the legacy GPIO API and keeping track on
polarity inversion semantics in the driver, switch to use
GPIO descriptors for this driver and change all consumers
in the process.
This makes it possible to retire platform data completely:
the only remaining platform data member was "wakeup" which
was intended to make the vbus interrupt wakeup capable,
but was not set by any users and thus remained unused. VBUS
was not waking any devices up. Leave a comment about it so
later developers using the platform can consider setting it
to always enabled so plugging in USB wakes up the platform.

Commit e0d795e4f3 ("usb: irda: cleanup on ir-usb module") added a USB
IrDA header with common defines, but mistakingly switched to using the
class-descriptor baud-rate bitmask values for the outbound header.
This broke link-speed handling for rates above 9600 baud, but a device
would also be able to operate at the default 9600 baud until a
link-speed request was issued (e.g. using the TCGETS ioctl).

The last user of the phy generic platform data was
deleted in commit 1e041b6f31
("usb: dwc3: exynos: Remove dead code"). So get rid of
the platform data, which rids us of another consumer of
the legacy GPIO API at the same time. Make sure we
only inlcude <linux/gpio/consumer.h> which is all we use.
Alter the usb_phy_gen_create_phy() function prototype to
not pass any platform data as this is just hardcoded to
NULL at all locations calling it in the kernel.
Move the devm_gpiod_get* calls out of the if (of_node)
parenthesis, as these calls are generic and do not depend
on device tree, they are used by any hardware description.

Here is the big set of USB patches for 5.4-rc1.
Two major chunks of code are moving out of the tree and into the staging
directory, uwb and wusb (wireless USB support), because there are no
devices that actually use this protocol anymore, and what we have today
probably doesn't work at all given that the maintainers left many many
years ago. So move it to staging where it will be removed in a few
releases if no one screams.
Other than that, lots of little things. The usual gadget and xhci and
usb serial driver updates, along with a bunch of sysfs file cleanups due
to the driver core changes to support that. Nothing really major, just
constant forward progress.
All of these have been in linux-next for a while with no reported

The main change this time around is a cleanup of some of the oldest

using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still in

that we can compile a kernel that works on these along with most other
ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
but additional work is needed to complete this. Patches for the
remaining ARMv5 platforms have started but need more work and some

Support for the new ASpeed AST2600 gets added, this is based on the

USB: Changes for v5.4 merge window
With only 45 non-merge commits, we have a small merge window from the
Gadget perspective.
The biggest change here is the addition of the Cadence USB3 DRD
Driver. All other changes are small, non-critical fixes or smaller new
features like the improvement to BESL handling in dwc3.

The split into multiple structures of the "ll" register bank is
impractical. It makes it hard to add ll_lfps_timers_2 which is
at offset 0x794, which is outside of the existing "lfps" structure
and would require us to add yet another one.
Instead, move all the "ll" registers into a single usb338x_ll_regs
structure, and add ll_lfps_timers_2 while at it. It will be used
in a subsequent patch.

Patch moves some decoding functions from driver/usb/dwc3/debug.h driver
to driver/usb/common/debug.c file. These moved functions include:
dwc3_decode_get_status
dwc3_decode_set_clear_feature
dwc3_decode_set_address
dwc3_decode_get_set_descriptor
dwc3_decode_get_configuration
dwc3_decode_set_configuration
dwc3_decode_get_intf
dwc3_decode_set_intf
dwc3_decode_synch_frame
dwc3_decode_set_sel
dwc3_decode_set_isoch_delay
dwc3_decode_ctrl
These functions are used also in inroduced cdns3 driver.
All functions prefixes were changed from dwc3 to usb.
Also, function's parameters has been extended according to the name
of fields in standard SETUP packet.
Additionally, patch adds usb_decode_ctrl function to
include/linux/usb/ch9.h file.

Currently there's no option for the controller driver to report the
recommended Best Effort Service Latency (BESL) when operating with LPM
support. Add new fields in usb_dcd_config_params to export the
recommended baseline and deep BESL values for the function drivers to
set the proper BESL value in the BOS descriptor.

The usb core is the only major place in the kernel that checks for
a non-NULL device dma_mask to see if a device is DMA capable. This
is generally a bad idea, as all major busses always set up a DMA mask,
even if the device is not DMA capable - in fact bus layers like PCI
can't even know if a device is DMA capable at enumeration time. This
leads to lots of workaround in HCD drivers, and also prevented us from
setting up a DMA mask for platform devices by default last time we
tried.
Replace this guess with an explicit HCD_DMA that is set by drivers that
appear to have DMA support.

The USB buffer allocation code is the only place in the usb core (and in
fact the whole kernel) that uses is_device_dma_capable, while the URB
mapping code uses the uses_dma flag in struct usb_bus. Switch the buffer
allocation to use the uses_dma flag used by the rest of the USB code,
and create a helper in hcd.h that checks this flag as well as the
CONFIG_HAS_DMA to simplify the caller a bit.

The UWB and wusbcore code is long obsolete, so let us just move the code
out of the real part of the kernel and into the drivers/staging/

- USB gadget driver updates and fixes
- new USB gadget driver for some hardware, followed by a quick revert
of those patches as they were not ready to be merged...
- PHY driver updates
