When the link is in L1, hardware should return it to L0
automatically whenever a transaction targets a component on the
other end of the link (PCIe r5.0, sec 5.2).
The R-Car PCIe controller doesn't handle this transition correctly.
If the link is not in L0, an MMIO transaction targeting a downstream
device fails, and the controller reports an ARM imprecise external
abort.
Work around this by hooking the abort handler so the driver can
detect this situation and help the hardware complete the link state
transition.
When the R-Car controller receives a PM_ENTER_L1 DLLP from the
downstream component, it sets PMEL1RX bit in PMSR register, but then
the controller enters some sort of in-between state. A subsequent
MMIO transaction will fail, resulting in the external abort. The
abort handler detects this condition and completes the link state
transition by setting the L1IATN bit in PMCTLR and waiting for the
link state transition to complete.

More devices are cropping up requiring only Regmap initialisation and
child registration functionality. We currently only support that if
all required devices are represented by their own Device Tree nodes
complete with compatible strings.
However, not everyone is happy with adding empty nodes that provide no
additional device information into the Device Tree.
Rather than have a plethora of mostly empty, function-less drivers in
MFD, we'll support those simple cases in here instead via MFD cells.

The PRCMU driver defines this as a DT node but there are no bindings
for it and it needs no data from the device tree. Just spawn the
device directly in the same way as the watchdog.
Name it "db8500-cpuidle" since there are no ambitions to support any
more SoCs than this one.
This rids this annoying boot message:
[ 0.032610] cpuidle-dbx500: Failed to locate of_node [id: 0]
However I think the device still spawns and work just fine, despite
not finding a device tree node.

We cannot detect a (perhaps buggy) controller that is sending us
a completion for a request that was already completed (for example
sending a completion twice), this phenomenon was seen in the wild
a few times.
So to protect against this, we use the upper 4 msbits of the nvme sqe
command_id to use as a 4-bit generation counter and verify it matches
the existing request generation that is incrementing on every execution.
The 16-bit command_id structure now is constructed by:
| xxxx | xxxxxxxxxxxx |
gen request tag
This means that we are giving up some possible queue depth as 12 bits
allow for a maximum queue depth of 4095 instead of 65536, however we
never create such long queues anyways so no real harm done.

When clearing the chip-select mask, the controller will switch to chip
selecting the native CS0 line. Because the control register chip-select
mask is not updated in a single write this will cause undesirable
chip-selection of CS0 even when requesting to select other native
chip-select lines. This is additionally problematic as the chip-select
may still be asserted. With the ARMADA 38x SoC the controller will
assert both the desired native chip-select and CS0.
To avoid any undesirable behaviour with the chip-select lines, update
the control register with a single write. This avoids selecting CS0 and
causes the (de-)assert to apply at the same time.

It is expected from the clients to follow the below steps on an imported
dmabuf fd:
a) dmabuf = dma_buf_get(fd) // Get the dmabuf from fd
b) dma_buf_attach(dmabuf); // Clients attach to the dmabuf
o Here the kernel does some slab allocations, say for
dma_buf_attachment and may be some other slab allocation in the
dmabuf->ops->attach().
c) Client may need to do dma_buf_map_attachment().
d) Accordingly dma_buf_unmap_attachment() should be called.
e) dma_buf_detach () // Clients detach to the dmabuf.
o Here the slab allocations made in b) are freed.
f) dma_buf_put(dmabuf) // Can free the dmabuf if it is the last
reference.
Now say an erroneous client failed at step c) above thus it directly
called dma_buf_put(), step f) above. Considering that it may be the last
reference to the dmabuf, buffer will be freed with pending attachments
left to the dmabuf which can show up as the 'memory leak'. This should
at least be reported as the WARN().

DMA channel status "Transmit buffer unavailable(TBU)" bit is not
considered as a successful dma tx. Hence, it should not affect
all the irq count statistic.

Each completion ring entry has a valid bit to indicate that the entry
contains a valid completion event. The driver's main poll loop
__bnxt_poll_work() has the proper dma_rmb() to make sure the valid
bit of the next entry has been checked before proceeding further.
But when we call bnxt_rx_pkt() to process the RX event, the RX
completion event consists of two completion entries and only the
first entry has been checked to be valid. We need the same barrier
after checking the next completion entry. Add missing dma_rmb()
barriers in bnxt_rx_pkt() and other similar locations.
Fixes: 67a95e2022c7 ("bnxt_en: Need memory barrier when processing the completion ring.")

The sja1105 driver's initialization and teardown sequence is a chaotic
mess that has gathered a lot of cruft over time. It works because there
is no strict dependency between the functions, but it could be improved.
The basic principle that teardown should be the exact reverse of setup
is obviously not held. We have initialization steps (sja1105_tas_setup,
sja1105_flower_setup) in the probe method that are torn down in the DSA
.teardown method instead of driver unbind time.
We also have code after the dsa_register_switch() call, which implicitly
means after the .setup() method has finished, which is pretty unusual.
Also, sja1105_teardown() has calls set up in a different order than the
error path of sja1105_setup(): see the reversed ordering between
sja1105_ptp_clock_unregister and sja1105_mdiobus_unregister.
Also, sja1105_static_config_load() is called towards the end of
sja1105_setup(), but sja1105_static_config_free() is also towards the
end of the error path and teardown path. The static_config_load() call
should be earlier.
Also, making and breaking the connections between struct sja1105_port
and struct dsa_port could be refactored into dedicated functions, makes
the code easier to follow.
We move some code from the DSA .setup() method into the probe method,
like the device tree parsing, and we move some code from the probe
method into the DSA .setup() method to be symmetric with its placement
in the DSA .teardown() method, which is nice because the unbind function
has a single call to dsa_unregister_switch(). Example of the latter type
of code movement are the connections between ports mentioned above, they
are now in the .setup() method.
Finally, due to fact that the kthread_init_worker() call is no longer
in sja1105_probe() - located towards the bottom of the file - but in
sja1105_setup() - located much higher - there is an inverse ordering
with the worker function declaration, sja1105_port_deferred_xmit. To
avoid that, the entire sja1105_setup() and sja1105_teardown() functions
are moved towards the bottom of the file.
