This patch enables 'can_dma_sg' flag for ax88179_178a device
if the attached host controller supports building packet from
discontinuous buffers(DMA SG is possible), so TSO can be enabled
and skb fragment buffers can be passed to usb stack via urb->sg
directly.
With the patch, system CPU utilization decreased ~50% and throughput
increased by ~10% when doing iperf client test on one ARM A15 dual
core board.

ehci-hcd currently unlinks an interrupt QH when it becomes empty, that
is, after its last URB completes. This works well because in almost
all cases, the completion handler for an interrupt URB resubmits the
URB; therefore the QH doesn't become empty and doesn't get unlinked.
When we start using tasklets for URB completion, this scheme won't work
as well. The resubmission won't occur until the tasklet runs, which
will be some time after the completion is queued with the tasklet.
During that delay, the QH will be empty and so will be unlinked
unnecessarily.
To prevent this problem, this patch adds a 5-ms time delay before empty
interrupt QHs are unlinked. Most often, during that time the interrupt
URB will be resubmitted and thus we can avoid unlinking the QH.

The patch does the below improvement:
- think QH_STATE_COMPLETING as unlinking state since all URBs on the
endpoint should be in unlinking or unlinked when doing endpoint_disable()
- add "WARN_ON(!list_empty(&qh->qtd_list));" if qh->qh_state is
QH_STATE_LINKED because there shouldn't be any active transfer in qh
- when qh->qh_state is QH_STATE_LINKED, the QH(async or periodic)
should be in its corresponding list, so the search through the async
list isn't necessary.
- unlink periodic QH to speed up unlinking if the QH is in linked
state
Basically, only the last one is related with this patchset because
the assumption of "periodic qh self-unlinks on empty" isn't true
any more when we introduce unlink-wait for periodic qh.

There is no good reason to run complete() in hard interrupt
disabled context.
After switch to run complete() in tasklet, we will enable local IRQs
when calling complete() since we can do it at that time.
Even though we still disable IRQs now when calling complete()
in tasklet, the URB documentation is updated to claim complete()
will be run in tasklet context and local IRQs will be enabled, so
that USB drivers can know the change and avoid one deadlock caused
by: assume IRQs disabled in complete() and call spin_lock() to
hold lock which might be acquired in interrupt context.
Current spin_lock() usages in drivers' complete() will be cleaned
up at the same time, and once the cleanup is finished, local IRQs
will be enabled when calling complete() in tasklet.
Also fix description about type of usb_complete_t, and remove the
advice of running completion handler in tasklet for decreasing
system latency.

This patch implements the mechanism of giveback of URB in
tasklet context, so that hardware interrupt handling time for
usb host controller can be saved much, and HCD interrupt handling
can be simplified.
Motivations:
1), on some arch(such as ARM), DMA mapping/unmapping is a bit
time-consuming, for example: when accessing usb mass storage
via EHCI on pandaboard, the common length of transfer buffer is 120KB,
the time consumed on DMA unmapping may reach hundreds of microseconds;
even on A15 based box, the time is still about scores of microseconds
2), on some arch, reading DMA coherent memoery is very time-consuming,
the most common example is usb video class driver[1]
3), driver's complete() callback may do much things which is driver
specific, so the time is consumed unnecessarily in hardware irq context.
4), running driver's complete() callback in hardware irq context causes
that host controller driver has to release its lock in interrupt handler,
so reacquiring the lock after return may busy wait a while and increase
interrupt handling time. More seriously, releasing the HCD lock makes
HCD becoming quite complicated to deal with introduced races.
So the patch proposes to run giveback of URB in tasklet context, then
time consumed in HCD irq handling doesn't depend on drivers' complete and
DMA mapping/unmapping any more, also we can simplify HCD since the HCD
lock isn't needed to be released during irq handling.
The patch should be reasonable and doable:
1), for drivers, they don't care if the complete() is called in hard irq
context or softirq context
2), the biggest change is the situation in which usb_submit_urb() is called
in complete() callback, so the introduced tasklet schedule delay might be a
con, but it shouldn't be a big deal:
- control/bulk asynchronous transfer isn't sensitive to schedule
delay
- the patch schedules giveback of periodic URBs using
tasklet_hi_schedule, so the introduced delay should be very
small
- for ISOC transfer, generally, drivers submit several URBs
concurrently to avoid interrupt delay, so it is OK with the
little schedule delay.
- for interrupt transfer, generally, drivers only submit one URB
at the same time, but interrupt transfer is often used in event
report, polling, ... situations, and a little delay should be OK.
Considered that HCDs may optimize on submitting URB in complete(), the
patch may cause the optimization not working, so introduces one flag to mark
if the HCD supports to run giveback URB in tasklet context. When all HCDs
are ready, the flag can be removed.

The Tegra30 TRM recommends configuration of certain PHY parameters for

parameters:
- UTMIP_XCVR_HSSLEW: HS slew rate control.
- UTMIP_HSSQUELCH_LEVEL: HS squelch detector level
- UTMIP_HSDISCON_LEVEL: HS disconnect detector level.
These registers exist in Tegra20, but programming them hasn't been
necessary, so these parameters won't be set on Tegra20 to keep the
device trees backward compatible.
Additionally, the UTMIP_XCVR_SETUP parameter can be set from fuses
instead of a software-programmed value, as the optimal value can
vary between invidual boards. The boolean property
nvidia,xcvr-setup-use-fuses can be used to enable this behaviour.

The Tegra30 USB PHY is a bit different than the Tegra20 PHY:
- The EHCI controller supports the HOSTPC register extension, and some
of the fields that the PHY needs to modify (PHCD and PTS) have moved
to the new HOSTPC register.
- Some of the UTMI PLL configuration registers have moved from the USB
register space to the Clock-And-Reset controller space. In Tegra30
the clock driver is responsible for configuring the UTMI PLL.
- The USBMODE register must be explicitly written to enter host mode.
- Certain PHY parameters need to be programmed for optimal signal
quality. Support for this will be added in the next patch.

The has_hostpc capability bit indicates that the host controller has the

power saving features with the PHY Low Power Clock Disable (PHCD) bit.
However, some host controllers have the HOSTPC extensions but don't
support the low-power feature, so the PHCD bit must not be set on those
controllers. Add a separate capability bit for the low-power feature
instead, and change all existing users of has_hostpc to use this new
capability bit.
The idea for this commit is taken from an old 2012 commit that never got

- use rndis mode on tx side so we haveon interrupt for 4096 transfers.
- remove custom "transferred" hack and use dmaengine_tx_status() to

This moves the two instances from the big node into two child nodes. The
glue layer ontop does almost nothing.
There is one devices containing the control module for USB (2) phy,
(2) usb and later the dma engine. The usb device is the "glue device"
which contains the musb device as a child. This is what we do ever since.
The new file musb_am335x is just here to prob the new bus and populate
child devices.
There are a lot of changes to the dsps file as a result of the changes:
- musb_core_offset
This is gone. The device tree provides memory ressources information
for the device there is no need to "fix" things
- instances
This is gone as well. If we have two instances then we have have two
child enabled nodes in the device tree. For instance the SoC in beagle
bone has two USB instances but only one has been wired up so there is
no need to load and init the second instance since it won't be used.
- dsps_glue is now per glue device
In the past there was one of this structs but with an array of two and
each instance accessed its variable depending on the platform device
id.
- no unneeded copy of structs
I do not know why struct dsps_musb_wrapper is copied but it is not
necessary. The same goes for musb_hdrc_platform_data which allocated
on demand and then again by platform_device_add_data(). One copy is
