6e4b74e469 usb: renesas: fix scheduling in atomic context bug
The current renesas_usbhs driver triggers

BUG: scheduling while atomic: ksoftirqd/0/3/0x00000102

with enabled CONFIG_DEBUG_ATOMIC_SLEEP, by submitting DMA transfers from
an atomic (tasklet) context, which is not supported by the shdma dmaengine
driver. Fix it by switching to a work.

7983bc74fc usb: renesas: silence uninitialized variable report in usbhsg_recip_run_handle()
In drivers/usb/renesas_usbhs/mod_gadget.c::usbhsg_recip_run_handle()
the Coverity Prevent checker currently flags a warning about possibly
uninitialized use of 'ret' i usbhsg_recip_run_handle(). It does this
since it assumes we take one of the non-default branches in the switch
and then subsequently take the false branch in the 'if (func)' case
below. This exact scenario will never happen, but Coverity can't see
that for some reason. This patch initializes 'ret' to '0' when it is
declared which should shut up this report and won't really hurt - so
why not? At least then it's clear that 'ret' is always initialized..

14ff96e04c usb: renesas: pipe: convert a long if into a XOR operation
This is just a minor optimization for the long
if we have on the driver.

When we want to check that one input is true
and the other must be false, the bitwise XOR
operator will achieve that for us.

c1e4877a41 usb: renesas_usbhs: modify device attach method
Current renesas_usbhs had been assigning udev to each urb.
It was executed even though it was device0.
For this reason, the device0 had to set the new device address
which has still not been assigned. (it will be assigned on next step).
Current renesas_usbhs used fixed address for it.
but it is not good for USB hub support.
This patch modifies this issue.

7177aed44f usb: gadget: rename usb_gadget_driver::speed to max_speed
This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”.  This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.

This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures.  All
of those represent the *maximal* speed given entity supports.

After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
  supports, and
* usb_composite_driver::max_speed - maximal speed composite
  gadget supports.

75587f52c7 usb: gadget: renesas_usbhs: add usbhs_bus_get_speed()
current mod_gadget had got usb speed on
usbhsg_irq_dev_state() which is status change interrupt callback function.
And the usb speed data was included in its parameter.

But this style works for mod_gadget,
but doesn't work for mod_host which
isn't interrupted when device status was changed.

This patch add usbhs_bus_get_speed() to solve this issue.
