The F81532/534 had 4 clocksource 1.846/18.46/14.77/24MHz and baud rates
can be up to 1.5Mbits with 24MHz. But on some baud rate (384~500kps), the
TX side will send the data frame too close to treat frame error on RX
side. This patch will force all TX data frame with delay 1bit gap.

The F81532/534 can be disable port by manufacturer with
following H/W design.
1: Connect DCD/DSR/CTS/RI pin to ground.
2: Connect RX pin to ground.
In driver, we'll implements some detect method likes following:
1: Read MSR.
2: Turn MCR LOOP bit on, off and read LSR after delay with 60ms.
It'll contain BREAK status in LSR.

The F81532/534 had 3 output pin (M0/SD, M1, M2) with open-drain mode to
control transceiver. We'll read it from internal Flash with address
0x2f05~0x2f08 for 4 ports. The value is range from 0 to 7. The M0/SD is
MSB of this value. For a examples, If read value is 6, we'll write M0/SD,
M1, M2 as 1, 1, 0.

The F81532/534 had 4 clocksource 1.846/18.46/14.77/24MHz and baud rates
can be up to 1.5Mbits with 24MHz.
This device may generate data overrun when baud rate setting to 921600bps
or higher with old UART trigger level setting (8x14=112) with full
loading. We'll change trigger level from 8x14=112 to 8x8=64 to avoid data
overrun.
Also the read/write of EP0 will be affected by this patch. The worst case
of responding time is 20s when all serial port are full loading and trying
to access EP0, so we change EP0 timeout from 10 to 20s.

The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:
xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8

And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.
Falling back to USB mass storage can solve this problem, so ignore UAS

The old way of usb wakeup only supports platform with single xHCI IP,
such as mt8173, but mt2712 has two xHCI IPs, so rebuild its flow and
supports the new glue layer of usb wakeup on mt2712 which is different
from mt8173.
Due to there is a hardware bug with the LINE STATE wakeup mode on
mt8173 which causes wakeup failure by low speed devices, and also
because IP SLEEP mode can cover all functions of LINE STATE mode,
it is unused in fact, and will not support it later, so remove it at
the same time.

Upon usb composition switch there is possibility of ep0 file
release happening after gadget driver bind. In case of composition
switch from adb to a non-adb composition gadget will never gets
bound again resulting into failure of usb device enumeration. Fix
this issue by checking FFS_FL_BOUND flag and avoid extra
gadget driver unbind if it is already done as part of composition
switch.
This fixes adb reconnection error reported on Android running
v4.4 and above kernel versions. Verified on Hikey running vanilla
v4.15-rc7 + few out of tree Mali patches.

The error-handling pathways in usb_add_gadget_udc_release() are messed
up. Aside from the uninformative statement labels, they can deallocate
the udc structure after calling put_device(), which is a double-free.
This was observed by KASAN in automatic testing.
This patch cleans up the routine. It preserves the requirement that
when any failure occurs, we call put_device(&gadget->dev).

The patch removes unused TIOCSSERIAL ioctl case and adds the default block
to the switch. This will make the ioctl return -ENOTTY to user space (e.g.
setserial), which indicates that TIOCSSERIAL really isn't supported for
these devices currently.
Note that these (dummy) ioctl implementations where added by commit
2f430b4bbae7 ("USB: ark3116: Add TIOCGSERIAL and TIOCSSERIAL ioctl
calls.") back in 2006. This in turn appears to have been triggered by a
change in a user space tool, wvdial, which started erroring out if
either was missing.
There are some bug reports about that against wvdial from around that
time, and looking at the wvstreams (library) code now, it looks like the
issue has indeed been resolved by handling errors more gracefully (e.g.
just logging them).
User space really should not make assumptions about these ioctl always
being implemented, but if this turns out to be a problem for anyone
using this driver, we'll add TIOCSSERIAL back in some form.

Adding phy calibration sequence for USB 3.0 DRD PHY present on
Exynos5420/5800 systems.
This calibration facilitates setting certain PHY parameters viz.
the Loss-of-Signal (LOS) Detector Threshold Level, as well as
Tx-Vboost-Level for Super-Speed operations.
Additionally we also set proper time to wait for RxDetect measurement,
for desired PHY reference clock, so as to solve issue with enumeration
of few USB 3.0 devices, like Samsung SUM-TSB16S 3.0 USB drive
on the controller.
We are using CR_port for this purpose to send required data
to override the LOS values.

The issue is caused by the xhci ring structures being reallocated
when the system is resumed, but pointers to the old structures
being retained in the debugfs files "private" field:
The proposed patch fixes this issue by storing a pointer to the xhci_ring
field in the xhci device structure in debugfs rather than directly
storing a pointer to the xhci_ring.

USB 3.1 devices are not detected as 3.1 capable since 4.15-rc3 due to a
off by one in commit 81cf4a45360f ("USB: core: Add type-specific length
check of BOS descriptors")
It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes
the zero based SSAC as argument, not the actual count of sublink speed
attributes.
USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1."
The type-specific length check patch was added to stable and needs to be
fixed there as well
