The detect function had a comment "Make compiler happy" when id did not
read the second configuration register. As it turns out, the code was
checking the contents of this register for manufacturer ID 0xA1 (NXP
Semiconductor/Philips), but never actually read the register. So it
wasn't surprising that the compiler complained, and it indeed had a point.
Fix the code to read the register contents for manufacturer ID 0xa1.
At the same time, the code was reading the register for manufacturer ID
0x41 (Analog Devices), but it was not using the results. In effect it was
just checking if reading the register returned an error. That doesn't
really add much if any value, so stop doing that.

support it separately. Hence squish the linux/platform_data/ad5755.h
header into the c file and drop accessing the platform data directly.
Done by inspection only. Mostly completely mechanical with the
exception of a few places where default value handling is
cleaner done by first setting the value, then calling the
firmware reading function but and not checking the return value,
as opposed to reading firmware then setting the default if an error
occurs.

IIO triggers are software IRQ chips that split an incoming IRQ into
separate IRQs routed to all devices using the trigger.
When all consumers are done then a trigger callback reenable() is
called. There are a few circumstances under which this can happen
in atomic context.
1) A single user of the trigger that calls the iio_trigger_done()
function from interrupt context.
2) A race between disconnecting the last device from a trigger and
the trigger itself sucessfully being disabled.
To avoid a resulting scheduling whilst atomic, close this second corner
by using schedule_work() to ensure the reenable is not done in atomic
context.
Note that drivers must be careful to manage the interaction of
set_state() and reenable() callbacks to ensure appropriate reference
counting if they are relying on the same hardware controls.
Deliberately taking this the slow path rather than via a fixes tree
because the error has hard to hit and I would like it to soak for a while
before hitting a release kernel.

The AD74412R and AD74413R are quad-channel, software configurable,
input/output solutions for building and process control applications.
They contain functionality for analog output, analog input, digital input,
resistance temperature detector, and thermocouple measurements integrated
into a single chip solution with an SPI interface.
The devices feature a 16-bit ADC and four configurable 13-bit DACs to
provide four configurable input/output channels and a suite of diagnostic
functions.
The AD74413R differentiates itself from the AD74412R by being
HART-compatible.
When configured with channel 0 as voltage output, channel 1 as current
output, channel 2 as voltage input and channel 3 as current input, the
following structure is created under the corresponding IIO device.

The sja1105 driver messes with the tagging protocol's state when PTP RX
timestamping is enabled/disabled. This is fundamentally necessary
because the tagger needs to know what to do when it receives a PTP
packet. If RX timestamping is enabled, then a metadata follow-up frame
is expected, and this holds the (partial) timestamp. So the tagger plays
hide-and-seek with the network stack until it also gets the metadata
frame, and then presents a single packet, the timestamped PTP packet.
But when RX timestamping isn't enabled, there is no metadata frame
expected, so the hide-and-seek game must be turned off and the packet
must be delivered right away to the network stack.
Considering this, we create a pseudo isolation by devising two tagger
methods callable by the switch: one to get the RX timestamping state,
and one to set it. Since we can't export symbols between the tagger and
the switch driver, these methods are exposed through function pointers.
After this change, the public portion of the sja1105_tagger_data
contains only function pointers.

protocol driver"
This reverts commit 6d709cadfde68dbd12bef12fcced6222226dcb06.
The above change was done to avoid calling symbols exported by the
switch driver from the tagging protocol driver.
With the tagger-owned storage model, we have a new option on our hands,
and that is for the switch driver to provide a data consumer handler in
the form of a function pointer inside the ->connect_tag_protocol()
method. Having a function pointer avoids the problems of the exported
symbols approach.
By creating a handler for metadata frames holding TX timestamps on
SJA1110, we are able to eliminate an skb queue from the tagger data, and
replace it with a simple, and stateless, function pointer. This skb
queue is now handled exclusively by sja1105_ptp.c, which makes the code
easier to follow, as it used to be before the reverted patch.

Currently, struct sja1105_tagger_data is a part of struct
sja1105_private, and is used by the sja1105 driver to populate dp->priv.
With the movement towards tagger-owned storage, the sja1105 driver
should not be the owner of this memory.
This change implements the connection between the sja1105 switch driver
and its tagging protocol, which means that sja1105_tagger_data no longer
stays in dp->priv but in ds->tagger_data, and that the sja1105 driver
now only populates the sja1105_port_deferred_xmit callback pointer.
The kthread worker is now the responsibility of the tagger.
The sja1105 driver also alters the tagger's state some more, especially
with regard to the PTP RX timestamping state. This will be fixed up a
bit in further changes.

The TX timestamp ID is incremented by the SJA1110 PTP timestamping
callback (->port_tx_timestamp) for every packet, when cloning it.
It isn't used by the tagger at all, even though it sits inside the
struct sja1105_tagger_data.
Also, serialization to this structure is currently done through
tagger_data->meta_lock, which is a cheap hack because the meta_lock
isn't used for anything else on SJA1110 (sja1105_rcv_meta_state_machine
isn't called).
This change moves ts_id from sja1105_tagger_data to sja1105_private and
introduces a dedicated spinlock for it, also in sja1105_private.

When the ocelot-8021q driver was converted to deferred xmit as part of
commit 8d5f7954b7c8 ("net: dsa: felix: break at first CPU port during
init and teardown"), the deferred implementation was deliberately made
subtly different from what sja1105 has.
The implementation differences lied on the following observations:
- There might be a race between these two lines in tag_sja1105.c:
skb_queue_tail(&sp->xmit_queue, skb_get(skb));
kthread_queue_work(sp->xmit_worker, &sp->xmit_work);
and the skb dequeue logic in sja1105_port_deferred_xmit(). For
example, the xmit_work might be already queued, however the work item
has just finished walking through the skb queue. Because we don't
check the return code from kthread_queue_work, we don't do anything if
the work item is already queued.
However, nobody will take that skb and send it, at least until the
next timestampable skb is sent. This creates additional (and
avoidable) TX timestamping latency.
To close that race, what the ocelot-8021q driver does is it doesn't
keep a single work item per port, and a skb timestamping queue, but
rather dynamically allocates a work item per packet.
- It is also unnecessary to have more than one kthread that does the
work. So delete the per-port kthread allocations and replace them with
a single kthread which is global to the switch.
This change brings the two implementations in line by applying those
observations to the sja1105 driver as well.

This code is not necessary and complicates the conversion of this driver
to tagger-owned memory. If there is a PTP packet that is sent
concurrently with the port getting disabled, the deferred xmit mechanism
is robust enough to time out when it sees that it hasn't been delivered,
and recovers.

The felix driver makes very light use of dp->priv, and the tagger is
effectively stateless. dp->priv is practically only needed to set up a
callback to perform deferred xmit of PTP and STP packets using the
ocelot-8021q tagging protocol (the main ocelot tagging protocol makes no
use of dp->priv, although this driver sets up dp->priv irrespective of
actual tagging protocol in use).
struct felix_port (what used to be pointed to by dp->priv) is removed
and replaced with a two-sided structure. The public side of this
structure, visible to the switch driver, is ocelot_8021q_tagger_data.
The private side is ocelot_8021q_tagger_private, and the latter
structure physically encapsulates the former. The public half of the
tagger data structure can be accessed through a helper of the same name
(ocelot_8021q_tagger_data) which also sanity-checks the protocol
currently in use by the switch. The public/private split was requested
by Andrew Lunn.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk driver fixes from Stephen Boyd:
- Fix qcom mux logic to look at the proper parent table member. Luckily
this clk type isn't very common.
- Don't kill clks on qcom systems that use Trion PLLs that are enabled
out of the bootloader. We will simply skip programming the PLL rate
if it's already done.
- Use the proper clk_ops for the qcom sm6125 ICE clks.
- Use module_platform_driver() in i.MX as it can be a module.
- Fix a UAF in the versatile clk driver on an error path.

When hisi_qm_resume() returns 0, it indicates that the device has started
successfully. If the device fails to start, hisi_qm_resume() needs to
return the actual error code to the caller instead of 0.

Octeon TX2 CPT has three type of engines to handle symmetric, asymmetric
and ipsec specific workload. For better utilization, these engines can
be grouped to custom groups at runtime.
This patch adds APIs to create and delete custom CPT engine groups.

We should not call pm_runtime_resume_and_get where the reference
count is expected to be incremented unconditionally. This patch
reverts these calls to the original unconditional get_sync call.
