For some reason USDHC and USB access crashes the kernel if the
OCOTP clock is not enabled. It seems not to be software related
since there is no direct access from the USDHC/Chipidea USB
driver to the OCOTP IP. It might be that the hardware checks
the fuses to determine if the particular SoC is supposed to
let user access a certain peripheral...

The device tree property fsl,legacy-bch-geometry was only evaluated
when nand-on-flash-bbt was also defined. This looks wrong.
In mainline (as of 4.12) fsl,legacy-bch-geometry doesn't exist,
its functionality seems to be taken over by the fsl,use-minimum-ecc
property and it is used independent of nand-on-flash-bbt.
The move of code gets also rid of the following compiler warning:

[ Upstream commit 3fa53ec2ed885b0aec3f0472e3b4a8a6f1cd748c ]
The irq chip callbacks irq_request/release_resources() have absolutely no
business with masking and unmasking the irq.
The core code unmasks the interrupt after complete setup and masks it
before invoking irq_release_resources().
The unmask is actually harmful as it happens before the interrupt is
completely initialized in __setup_irq().
Remove it.

[ Upstream commit d81ece747d8727bb8b1cfc9a20dbe62f09a4e35a ]
The PH16 pin has a function with mux id 0x5, which is the DET pin of the
"sim" (smart card reader) IP block.
This function is missing in old versions of A10/A20 SoCs' datasheets and
user manuals, so it's also missing in the old drivers. The newest A10
Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and
it's discovered during implementing R40 pinctrl driver.
Add it to the driver. As we now merged A20 pinctrl driver to the A10
one, we need to only fix the A10 driver now.

[ Upstream commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 ]
Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume
On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.
In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.
As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

[ Upstream commit 94c43b9897abf4ea366ed4dba027494e080c7050 ]
Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure. This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.
The logic for doing this is careful to check that the device is still
connected. But this check is inadequate if the device disconnects and
reconnects before the check is done. The symptom is that a device
works, but much more slowly than it is capable of operating.
The situation was made worse recently by commit 22547c4cc4fe ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.
This patch makes the check more robust. If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

[ Upstream commit a3507e48d3f99a93a3056a34a5365f310434570f ]
The TSL2563 driver provides three iio channels, two of which are raw ADC
channels (channel 0 and channel 1) in the device and the remaining one
is calculated by the two. The ADC channel 0 only supports programmable
interrupt with threshold settings and this driver supports the event but
the generated event code does not contain the corresponding iio channel
type.
This is going to change userspace ABI. Hopefully fixing this to be
what it should always have been won't break any userspace code.

Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared
HCD and set HCD_FLAG_DEAD for it, in analogy with what is done for

Among other thigs, this prevents check_root_hub_suspended() from
returning -EBUSY for dead HCDs which helps to work around system
suspend issues in some situations.
This actually fixes occasional suspend failures on one of my test

The client was freeing the nfs4_ff_layout_ds, but not the contained
nfs4_ff_ds_version array.

[ Upstream commit 68227c03cba84a24faf8a7277d2b1a03c8959c2c ]
Before the patch, the flock flag could remain uninitialized for the
lifespan of the fuse_file allocation. Unless set to true in
fuse_file_flock(), it would remain in an indeterminate state until read in
an if statement in fuse_release_common(). This could consequently lead to
taking an unexpected branch in the code.
The bug was discovered by a runtime instrumentation designed to detect use
of uninitialized memory in the kernel.

[ Upstream commit 978d13d60c34818a41fc35962602bdfa5c03f214 ]
This patch fixes a bug associated with iscsit_reset_np_thread()
that can occur during parallel configfs rmdir of a single iscsi_np
used across multiple iscsi-target instances, that would result in
hung task(s) similar to below where configfs rmdir process context
was blocked indefinately waiting for iscsi_np->np_restart_comp
to finish:

It would happen because each iscsit_reset_np_thread() sets state
to ISCSI_NP_THREAD_RESET, sends SIGINT, and then blocks waiting
for completion on iscsi_np->np_restart_comp.
However, if iscsi_np was active processing a login request and
more than a single iscsit_reset_np_thread() caller to the same
iscsi_np was blocked on iscsi_np->np_restart_comp, iscsi_np
kthread process context in __iscsi_target_login_thread() would
flush pending signals and only perform a single completion of
np->np_restart_comp before going back to sleep within transport
specific iscsit_transport->iscsi_accept_np code.
To address this bug, add a iscsi_np->np_reset_count and update
__iscsi_target_login_thread() to keep completing np->np_restart_comp
until ->np_reset_count has reached zero.

[ Upstream commit ea8dc5b4cd2195ee582cae28afa4164c6dea1738 ]
On receiving text request iscsi-target allocates buffer for
payload in iscsit_handle_text_cmd() and assigns buffer pointer
to cmd->text_in_ptr, this buffer is currently freed in
iscsit_release_cmd(), if iscsi-target sets 'C' bit in text
response then it will receive another text request from the
initiator with ttt != 0xffffffff in this case iscsi-target
will find cmd using itt and call iscsit_setup_text_cmd()
which will set cmd->text_in_ptr to NULL without freeing
previously allocated buffer.
This patch fixes this issue by calling kfree(cmd->text_in_ptr)
in iscsit_setup_text_cmd() before assigning NULL to it.
For the first text request cmd->text_in_ptr is NULL as
cmd is memset to 0 in iscsit_allocate_cmd().
