commit 3921426 (usb: dwc3: core: move

of the coherent memory we use as event
buffers on dwc3 driver.
If the driver is compiled as a dynamically

to leak the coherent memory allocated during
->probe() because dwc3_free_event_buffers()
is never called during ->remove().

commit 392142 moved event buffer allocation out of dwc3_core_init() but
event buffer allocation uses the cached copy of hwparams to determine
the number of event buffers and the caching is done in dwc3_core_init.
So moved dwc3_cache_hwparams function before dwc3_alloc_event_buffers so
that dwc3_alloc_event_buffers sees the correct number of event buffers.

now that clk API provides no-op stubs when it's not linked
into the kernel.
We're also switching over event buffer allocation to devm_kzalloc()
and moving the allocation out of dwc3_core_init() so that can be
re-used when implementing PM support for v3.9.
After the introduction of PLATFORM_DEVID_AUTO, we can also drop the
homebrew platform device ID handling we had on dwc3 core and let
driver core take care of that for us.

XferNotReady(DATA) event in some conditions). This issue which
show up as a SETUP transfers which wouldn't complete ever and
we would fail TD 7.06 of the Link Layer Test from USB-IF and
Lecroy's USB3 Exerciser.
We also fix a long standing bug regarding EP0 enable sequencing
where we weren't setting a particular bit (Ignore Sequence
Number). Since we never saw any problems caused by that, it
didn't deserve being sent to stable tree.
On this pull request we also fix Burst Size initialization which

Burst Size to the maximum value on non-SuperSpeed mode. Again,
since we never saw any problems caused by that, we're not sending

You will also find some sparse warnings fix, a fix for missed
isochronous packets when the endpoint is already busy, and a
fix for synchronization delay on dwc3_stop_active_transfer().

must cache all 32-bits properly rather than masking
the top 16-bits.
This will fix all revision checks we have on current
driver.

We mask the correct bits within the wrong register. The power
optimization mode is stored hwparam1 register and not in hwparam0.

A few inits like the scale value or the removal of the DISSCRAMBLE is
done in the gadget code however it touches a general register.
Move this piece to the core.c file since it is likely to be requied by
both, parts of the core (device and host).

There are two where need to set operational mode:
- during initialization while we decide to run in host,device or DRD
mode
- at runtime via the debugfs interface.
This patch provides a new function which sets the operational mode and
moves its initialiation to the mode switch instead in the gadget code
itself.

hardware will tell us how many event buffers we
need to support, so let's allocate the array
dynamically too.

if we want to support situations where we have
both SoC and PCIe versions of the IP on the same
platform, we need to have sequential numbers between
them, otherwise we will still have name collisions.
Because of that, we need to move dwc3_get/put_device_id()
to core.c and export that symbol to be used by glue
layers.
