The devicetree ABI was broken on purpose by commit 6d532143c915
("watchdog: jz4740: Use regmap provided by TCU driver"), and
commit 1d9c30745455 ("watchdog: jz4740: Use WDT clock provided
by TCU driver"). The commit message of the latter explains why the ABI
was broken.
However, the current devicetree files were not updated to the new ABI
described in Documentation/devicetree/bindings/timer/ingenic,tcu.txt,
so the watchdog driver would not probe.
Fix this problem by updating the watchdog nodes to comply with the new
ABI.

Clang does not support this option and errors out:
clang-11: error: unknown argument: '-mexplicit-relocs'
Clang does not appear to need this flag like GCC does because the jalr
check that was added in commit 976c23af3ee5 ("mips: vdso: add build
time check that no 'jalr t9' calls left") passes just fine with
$ make ARCH=mips CC=clang CROSS_COMPILE=mipsel-linux-gnu- malta_defconfig arch/mips/vdso/
even before commit d3f703c4359f ("mips: vdso: fix 'jalr t9' crash in

-mrelax-pic-calls has been supported since clang 9, which is the
earliest version that could build a working MIPS kernel, and it is the

This reverts commit 219d2e9dfda9431b808c28d5efc74b404b95b638.
The call chain below requires the cm_id_priv's destination address to be
setup before performing rdma_bind_addr(). Otherwise source port allocation
fails as cma_port_is_unique() no longer sees the correct tuple to allow
duplicate users of the source port.
rdma_resolve_addr()
cma_bind_addr()
rdma_bind_addr()
cma_get_port()
cma_alloc_any_port()
cma_port_is_unique() <- compared with zero daddr
This can result in false failures to connect, particularly if the source
port range is restricted.

The RK3328 reference design uses an external line driver IC as a buffer
on the analog codec output, enabled by the GPIO_MUTE pin, and such a
configuration is currently assumed in the codec driver's direct poking
of GRF_SOC_CON10 to control the GPIO_MUTE output value. However, some
boards wire up analog audio yet use that pin for some other purpose, so
that assumption doesn't always hold. Update this functionality to rely
on an explicit GPIO descriptor, such that it can be managed at the
board level.

Existing RK3328 codec drivers have overloaded the GRF phandle to assume
implicit control of the limited-function GPIO_MUTE pin, which is usually
used to enable an external audio line driver IC. Since this pin has a
proper binding of its own (see gpio/rockchip,rk3328-grf-gpio.txt), make
a GPIO explicit in the codec binding too. This will help avoid ambiguity
on boards that use that pin for some other purpose.
(and while touching the example, enforce the "don't include status" rule)

This reverts commit b2354e4009a773c00054b964d937e1b81cb92078.
This change might have been desirable to ensure the uniqueness of
the component name. It would have helped to better support linux
devices which register multiple components, something is which more
common than initially thought.
However, some card driver are directly using dev_name() to fill the
component names of the dai_link which is a problem if want to change
the way ASoC generates the component names.
Until we figure out the appropriate way to deal with this, revert the
change and keep the names as they were. There might be a couple of warning
related to debugfs (which were already present before the change) but it
is still better than breaking working audio cards.

Extending the Arm SMMU driver to allow for modular builds changed
KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be
built from the multiple existing object files without the need to rename
any source files.
This inadvertently changed the name of the driver parameters, which may
lead to runtime issues if bootloaders are relying on the old names for
correctness (e.g. "arm-smmu.disable_bypass=0").
Although MODULE_PARAM_PREFIX can be overridden to restore the old naming
for builtin parameters, only the new name is matched by modprobe and so
loading the driver as a module would cause parameters specified on the
kernel command line to be ignored. Instead, rename "arm_smmu_mod" to
"arm_smmu". Whilst it's a bit of a bodge, this allows us to create a
single module without renaming any files and makes use of the fact that
underscores and hyphens can be used interchangeably in parameter names.

Currently, the implementation of qcom_iommu_domain_free() is guaranteed
to do one of two things: WARN() and leak everything, or dereference NULL
and crash. That alone is terrible, but in fact the whole idea of trying
to track the liveness of a domain via the qcom_domain->iommu pointer as
a sanity check is full of fundamentally flawed assumptions. Make things
robust and actually functional by not trying to be quite so clever.

different from our runtime PM autosuspend rate MDM6600_MODEM_IDLE_DELAY_MS

Serious screen flickering when Stoney Ridge outputs to a 4K monitor.
Use identity-mapping and PCI ATS doesn't help this issue.
According to Alex Deucher, IOMMU isn't enabled on Windows, so let's do
the same here to avoid screen flickering on 4K monitor.

The calcuation for limit of reserved token did not take into account the
change the user wanted vs the current group reserved token. This causes
changing of the reserved token to be possible only after we set the value
of the reserved token back to 0. Fix calculation so we can set a value that
is non zero for reserved token.

When we receive back the descriptor of the terminated transfer the cookie
must be marked as completed to make sure that the accounting is correct.
In udma_tx_status() the status should be marked as completed if the channel
is no longer running (it can only happen if the channel is not yet started
for the first time, or after a channel termination).

It should be possible to pause, resume and check the pause state of a
channel even if we do not have active transfer.
udma_is_chan_paused() can trigger NULL pointer reference in it's current
form when the status is checked while uc->desc is NULL.

Use the generic TR setup function to get the TR counters for both cyclic
and slave_sg transfers.
This way the period_size for cyclic and sg_dma_len() for slave_sg can be
as large as (SZ_64K - 1) * (SZ_64K - 1) and we can handle cases when the
length is >SZ_64K and a prime number.

When a channel is asked to be stopped (teardown) and we do not have active
descriptor to receive stale data buffered on the remote side then the
teardown will not complete as UDMA needs a descriptor to be able to flush
out the DMA pipe.
The peer is trying to push the data to UDMA in teardown, but UDMA is
pushing back because it has no descriptor which would allow it to drain the
data.
The workaround is to create 1K 'trashcan' to receive the discarded data and
set up descriptors for packet and TR mode channels.
When a channel is stopped and there is no active descriptor then a
descriptor is pushed to the ring for UDMA before the teardown is initiated.

In some cases (McSPI for example) the jiffie and delayed_work based

Switch to use ktime/usleep_range based implementation to be able

When FW doesn't support reformat option over SW-steering managed table,
the driver shouldn't pass this.

The pool sizes represent the pool sizes in the fw. when we request
a pool size from fw, it will return the next possible group.
We track how many pools the fw has left and start requesting groups
from the big to the small.
When we start request 4k group, which doesn't exists in fw, fw
wants to allocate the next possible size, 64k, but will fail since
its exhausted. The correct smallest pool size in fw is 128 and not 4k.
