f2fs_inode_info.flags is unsigned long variable, it has 32 bits
in 32bit architecture, since we introduced FI_MMAP_FILE flag
when we support data compression, we may access memory cross
the border of .flags field, corrupting .i_sem field, result in
below deadlock.
To fix this issue, let's expand .flags as an array to grab enough
space to store new flags.

This patch fix the bug that if the property maximum-speed of dwc3 is
configured to high-speed in DTS, gadget connection will be slow.
Before gadget connection, it is necessary to write register DCFG to set
maximum speed, if you don't, dwc3 will generate Erratic Error Event many
times and results to slow connection. Actually, maximum speed will be
set when Android layer call udc_bind_to_driver but it will fail when
dwc3 runtime-suspended. For Rockchip SoCs, dwc3 will be suspended as long
as USB cable is unplugged, so we add udc_set_speed before dwc3 runtime
resume.

When I test the uvc gadget function, I find that the uvc
gadget can only transfer the first frame image and then
stop unexpectedly.
Without this patch, the isochronous endpoints doesn't wait
for a XferNotReady event to start the next frame image, and
fail to transfer data. In this case, we will get an endpoint
event DWC3_DEPEVT_XFERINPROGRESS and the event status is
DEPEVT_STATUS_MISSED_ISOC, and the original code try to
issue an EndTransfer command if the started_list is empty.
However, the started_list is never empty, so it doesn't issue
an EndTransfer command and not XferNotReady event happens.
To fix this problem, this patch firstly checks if the event
status is DEPEVT_STATUS_MISSED_ISOC and then unmap the isoc
request and move the request to the pending list. Then it
issue an EndTransfer command if the started_list is empty.
After the EndTransfer is completed, we will get a XferNotReady
event and it can start the isoc requests again.

We had a 100us delay to synchronize the END_TRANSFER command completion
before giving back requests to the function drivers. Now, the controller
driver can handle cancelled TRBs with the requests' cancelled_list and
it can also wait until the END_TRANSFER completion before starting new
transfers. Synchronization can simply base on the controller's command
completion interrupt. The 100us delay is no longer needed. Remove this
arbitrary delay.

that's the case. Some controller revisions depend on this. See

(cherry picked from commit da10bcdd6f)
While the END_TRANSFER command is sent but not completed, any request
dequeue during this time will cause the driver to issue the END_TRANSFER
command. The driver needs to submit the command only once to stop the
controller from processing further. The controller may take more time to
process the same command multiple times unnecessarily. Let's add a flag
DWC3_EP_END_TRANSFER_PENDING to check for this condition.

Probe devices asynchronously instead of the driver. This results in us
seeing the same behavior if the device is registered before the driver or
after. This way we can avoid serializing the initialization should the
driver not be loaded until after the devices have already been added.
The motivation behind this is that if we have a set of devices that
take a significant amount of time to load we can greatly reduce the time to
load by processing them in parallel instead of one at a time. In addition,
each device can exist on a different node so placing a single thread on one
CPU to initialize all of the devices for a given driver can result in poor
performance on a system with multiple nodes.
This approach can reduce the time needed to scan SCSI LUNs significantly.
The only way to realize that speedup is by enabling more concurrency which
is what is achieved with this patch.
To achieve this it was necessary to add a new member "async_driver" to the
device_private structure to store the driver pointer while we wait on the
deferred probe call.

(cherry picked from commit ef0ff68351)
Try to consolidate all of the locking and unlocking of both the parent and
device when attaching or removing a driver from a given device.
To do that I first consolidated the lock pattern into two functions
__device_driver_lock and __device_driver_unlock. After doing that I then
created functions specific to attaching and detaching the driver while
acquiring these locks. By doing this I was able to reduce the number of
spots where we touch need_parent_lock from 12 down to 4.
This patch should produce no functional changes, it is meant to be a code
clean-up/consolidation only.

(cherry picked from commit ed88747c6c)
Asynchronous driver probing can help much on kernel fastboot, and
this option can provide a flexible way to optimize and quickly verify
async driver probe.
Also it will help in below cases:
* Some driver actually covers several families of HWs, some of which
could use async probing while others don't. So we can't simply
turn on the PROBE_PREFER_ASYNCHRONOUS flag in driver, but use this
cmdline option, like igb driver async patch discussed at
https://www.spinics.net/lists/netdev/msg545986.html
* For SOC (System on Chip) with multiple spi or i2c controllers, most
of the slave spi/i2c devices will be assigned with fixed controller
number, while async probing may make those controllers get different
index for each boot, which prevents those controller drivers to be
async probed. For platforms not using these spi/i2c slave devices,
they can use this cmdline option to benefit from the async probing.

Innosilicon LVDS/TTL PHY implements LVDS TIA/EIA protocol.
Normally, Innosilicon LVDS/TTL PHY contains four 7-bit
parallel-load serial-out shift registers, a 7X clock PLL,
and five Low-Voltage Differential Signaling (LVDS) line drivers
in a single integrated circuit. These functions allow 28 bits
of single-ended LVTTL data to be synchronously transmitted over
five balanced-pair conductors for receipt by a compatible receiver.
In addition, Innosilicon LVDS/TTL PHY could extend from 4 lanes
to N lanes (N is required by the customer). Therefore, the TTL
lines extend respectively.
