The scaling down sequence requires the clock to be set
after selecting the corresponding bus-speed mode in the
controller.
The scaling up to HS400 requires the timing and clock to
be set to legacy.
Without the above configuration, bus-width switch fails,
further leading to CRC errors.

Some cases were reported on 3.18 where atomic unmovable allocations
of order 2 fails, but kswapd does not wakeup. And in such cases it
was seen that, when zone_watermark_ok check is performed to decide
whether to wake up kswapd, there were lot of CMA pages of order 2 and
above. This makes the watermark check succeed resulting in kswapd not
being woken up. But since these atomic unmovable allocations can't come
from CMA region, further atomic allocations keeps failing, without
kswapd trying to reclaim. Usually concurrent movable allocations result
in reclaim and improves the situtation, but the case reported was from
a network test which was resulting in only atomic skb allocations being
attempted. On 3.18 this was fixed by adding a cma free page counter and
accouting the cma free pages properly in watermark calculations.
Later this issue was indirectly fixed by the commit "mm, page_alloc:
only enforce watermarks for order-0 allocations".
But the commit "mm: add cma pcp list" brought the problem back because
it includes MIGRATE_CMA within MIGRATE_PCPTYPES, and thus watermark
check erroneously returns success for !ALLOC_CMA by finding free pages
in cma free list.

Roothub's (udev->dev) can be asynchronously suspended due to
power.async_suspend is set to true i.e. at time of system suspend and
resume, these devices' (usb1 and usb2) kobject count is decremented
and incremented respectively. hcd_release() API expects that shared_hcd
is being released first before hcd. Due to additional reference count
at time of system resume, it results into hcd_release() is called
first with hcd (primary) and then shared_hcd. With this,
usb_hcd_is_primary_hcd() API is returning true for both hcd and
shared_hcd which results into double free of bandwidth_mutex. Fix this
issue by identifying hcd to release bandwidth_mutex without depending
on which order hcd_release() is called with hcd and share_hcd.

Currently MTP driver is resetting string id during unbind, when
cable is disconnected. Due to this, composite driver might run out
of string ids, when it tries to allocate string id during next
composition switch to MTP. This results in composition switch failure
when MTP is selected and eventually causing USB enumeration failure.
Fix this by not resetting string id and allocate it once only.

If cable is disconnected while send_file work is in progress,
Endpoints will be disabled and state will be marked as OFFLINE.
As a part of endpoint disable pending requests will be retire out
with -ECONNRESET error. Due to this we will modify the device state
as ERROR in completion callback. If the state is not offline then
we will mark the device state to ready in send_file_work. This results
in mtp driver to not returning any error for next mtp_write operation
and mtp release will not be called.
Hence fix this issue by adding a proper check in completions to not
moving device state to ERROR in case of disconnect.
