Wait for Start Of Frame interrupt, then wait 20 us, before starting
port resume. Workaround for hardware issue that can cause the SOF to
be sent out at the same time as the phy speed change.

dma engine.

Calling the complete callback when a request is cancelled leads to
locking problems in the callback, which could be called from an IRQ
with no locks held, or from whatever context called
tegra_dma_dequeue_req. Instead, expect the caller to handle the
now-cancelled request as needed.
Also removes tegra_dma_dequeue, since all users can be trivially
converted to tegra_dma_dequeue_req.

Update tegra_init_emc to provide generic memory
vendor matching. Read values from EMC_MRR_0, to
uniquely identify memory types and compare them
to table of memory passed in.

tegra_assert_system_reset is called after the cache is disabled.
Calling writel will cause the PL310 store buffers to be drained,
which requires taking a spinlock. Taking a spinlock is not safe
after the caches are disabled. Convert to readl_relaxed and
writel_relaxed.

The kernel now receives wait tracking data (similar to gathers and
relocs) and compares the current syncpt with the threshold value.
If it's old, it gets a kernel mapping and rewrites the method data
to use a kernel reserved syncpt that is always 0 (so trivially pops
when seen by the HW).
Patch has dependency to the user-space patches

as the rate set while bringing-up rx dma during init, to decrease
start-up time.

get_spare_fuse was calling tegra_apb_readl and passing an
offset, but tegra_apb_readl requires a physical address.
Fix it by calling tegra_fuse_readl instead, which takes
an offset.
Fixes a crash booting on A03 parts, where get_spare_fuse
is used to determine the difference between A03 and A03
prime.

In mtp_read(), if wait_event_interruptible() returns an error, we need to
remove the request from the EP queue. Else, on the next call to mtp_read(), we
will attempt to enqueue the request again, potentially corrupting the
queue. This is what happens with musb_gadget_queue(), which does not check for
duplicate requests.
Based on a similar change to f_adb.c
