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.

Pull dma-mapping updates from Christoph Hellwig:

 - move the USB special case that bounced DMA through a device bar into
   the USB code instead of handling it in the common DMA code (Laurentiu
   Tudor and Fredrik Noring)

 - don't dip into the global CMA pool for single page allocations
   (Nicolin Chen)

 - fix a crash when allocating memory for the atomic pool failed during
   boot (Florian Fainelli)

 - move support for MIPS-style uncached segments to the common code and
   use that for MIPS and nios2 (me)

 - make support for DMA_ATTR_NON_CONSISTENT and
   DMA_ATTR_NO_KERNEL_MAPPING generic (me)

 - convert nds32 to the generic remapping allocator (me)

 "Here is the big USB and PHY driver pull request for 5.3-rc1.

  Lots of stuff here, all of which has been in linux-next for a while
  with no reported issues. Nothing is earth-shattering, just constant
  forward progress for more devices supported and cleanups and small
  fixes:

   - 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

   - Lots of new driver additions and cleanups with a few fixes mixed

USB: more changes for v5.3 merge window

Turns out a few more important changes came about. We have the new
Cadence DRD Driver being added here and that's the biggest, most
important part.

Together with that we have suport for new imx7ulp phy. Support for
TigerLake Devices on dwc3. Also a couple important fixes which weren't
completed in time for the -rc cycle.

Patch moves some decoding functions from driver/usb/dwc3/debug.h driver
to driver/usb/gadget/debug.c file. These moved functions include:
    dwc3_decode_get_status
    dwc3_decode_set_clear_feature

    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/gadget.h file.

usb: changes for v5.3 merge window

The biggest part here is a set of patches removing unnecesary variables
from several drivers.

Meson-g12a's dwc3 glue implemented IRQ-based OTG/DRD role swap.

Qcom's dwc3 glue added support for ACPI, mainly for the AArch64-based
SoCs.

DWC3 also got support for Intel Elkhart Lake platforms.

In the future, each struct renesas_usbhs_driver_param is stored on
the each platform related source code (e.g. rcar3.c). So, to simplify
the source code, this patch adds a new flag has_new_pipe_configs.
