It is very rare to see versions of GCC prior to 4.8 being used to build
the mainline kernel. These old compilers are also know to have codegen
issues which can lead to silent miscompilation:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58145
Raise the minimum GCC version for kernel build to 4.8 and remove some
tautological Kconfig dependencies as a consequence.

To rehash a previous explanation given in commit 1c44ce560b4d ("net:
mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is
up"), the switch driver operates the in a mode where a single VLAN can
be transmitted as untagged on a particular egress port. That is the
"native VLAN on trunk port" use case.
The configuration for this native VLAN is driven in 2 ways:
- Set the egress port rewriter to strip the VLAN tag for the native
VID (as it is egress-untagged, after all).
- Configure the ingress port to drop untagged and priority-tagged
traffic, if there is no native VLAN. The intention of this setting is
that a trunk port with no native VLAN should not accept untagged
traffic.
Since both of the above configurations for the native VLAN should only
be done if VLAN awareness is requested, they are actually done from the
ocelot_port_vlan_filtering function, after the basic procedure of
toggling the VLAN awareness flag of the port.
But there's a problem with that simplistic approach: we are trying to
juggle with 2 independent variables from a single function:
- Native VLAN of the port - its value is held in port->vid.
- VLAN awareness state of the port - currently there are some issues
here, more on that later*.
The actual problem can be seen when enslaving the switch ports to a VLAN
filtering bridge:
0. The driver configures a pvid of zero for each port, when in
standalone mode. While the bridge configures a default_pvid of 1 for
each port that gets added as a slave to it.
1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true.
The VLAN-filtering-dependent portion of the native VLAN
configuration is done, considering that the native VLAN is 0.
2. The bridge calls ocelot_vlan_add with vid=1, pvid=true,
untagged=true. The native VLAN changes to 1 (change which gets
propagated to hardware).
3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the
VLAN-filtering-dependent portion of the native VLAN configuration,
for the new native VLAN of 1. One can notice that after toggling "ip
link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0
type bridge vlan_filtering 1", the new native VLAN finally makes it
through and untagged traffic finally starts flowing again. But
obviously that shouldn't be needed.
So it is clear that 2 independent variables need to both re-trigger the
native VLAN configuration. So we introduce the second variable as
ocelot_port->vlan_aware.
*Actually both the DSA Felix driver and the Ocelot driver already had
each its own variable:
- Ocelot: ocelot_port_private->vlan_aware
- Felix: dsa_port->vlan_filtering
but the common Ocelot library needs to work with a single, common,
variable, so there is some refactoring done to move the vlan_aware
property from the private structure into the common ocelot_port
structure.

<michael@walle.cc>:
The Kontron sl28cpld is a board management chip providing gpio, pwm, fan
monitoring and an interrupt controller. For now this controller is used on
the Kontron SMARC-sAL28 board. But because of its flexible nature, it
might also be used on other boards in the future. The individual blocks
(like gpio, pwm, etc) are kept intentionally small. The MFD core driver
then instantiates different (or multiple of the same) blocks. It also
provides the register layout so it might be updated in the future without a
device tree change; and support other boards with a different layout or
functionalities.
See also [1] for more information.
This is my first take of a MFD driver. I don't know whether the subsystem
maintainers should only be CCed on the patches which affect the subsystem
or on all patches for this series. I've chosen the latter so you can get a
more complete picture.

Changes since v1:
- use of_match_table in all drivers, needed for automatic module loading,
when using OF_MFD_CELL()
- add new gpio-regmap.c which adds a generic regmap gpio_chip implemention
- new patch for reqmap_irq, so we can reuse its implementation
- remove almost any code from gpio-sl28cpld.c, instead use gpio-regmap and
regmap-irq
- change the handling of the mfd core vs device tree nodes; add a new
property "of_reg" to the mfd_cell struct which, when set, is matched to
the unit-address of the device tree nodes.
- fix sl28cpld watchdog when it is not initialized by the bootloader.
Explicitly set the operation mode.
- also add support for kontron,assert-wdt-timeout-pin in sl28cpld-wdt.
As suggested by Bartosz Golaszewski:
- define registers as hex
- make gpio enum uppercase
- move parent regmap check before memory allocation
- use device_property_read_bool() instead of the of_ version
- mention the gpio flavors in the bindings documentation
As suggested by Guenter Roeck:
- cleanup #includes and sort them
- use devm_watchdog_register_device()
- use watchdog_stop_on_reboot()
- provide a Documentation/hwmon/sl28cpld.rst
- cleaned up the weird tristate->bool and I2C=y issue. Instead mention
that the MFD driver is bool because of the following intc patch
- removed the SL28CPLD_IRQ typo
As suggested by Rob Herring:
- combine all dt bindings docs into one patch
- change the node name for all gpio flavors to "gpio"
- removed the interrupts-extended rule
- cleaned up the unit-address space, see above

Add a new function regmap_add_irq_chip_np() with its corresponding
devm_regmap_add_irq_chip_np() variant. Sometimes one want to register
the IRQ domain on a different device node that the one of the regmap
node. For example when using a MFD where there are different interrupt
controllers and particularly for the generic regmap gpio_chip/irq_chip
driver. In this case it is not desireable to have the IRQ domain on
the parent node.

Check that the resolved slot (somewhat confusingly named 'start') is a
valid/allocated slot before doing the final comparison to see if the
specified gfn resides in the associated slot. The resolved slot can be
invalid if the binary search loop terminated because the search index
was incremented beyond the number of used slots.
This bug has existed since the binary search algorithm was introduced,
but went unnoticed because KVM statically allocated memory for the max
number of slots, i.e. the access would only be truly out-of-bounds if
all possible slots were allocated and the specified gfn was less than
the base of the lowest memslot. Commit 36947254e5f98 ("KVM: Dynamically
size memslot array based on number of used slots") eliminated the "all
possible slots allocated" condition and made the bug embarrasingly easy
to hit.
Fixes: 9c1a5d38780e6 ("kvm: optimize GFN to memslot lookup with large slots amount")

When acpi_extlog was added, we were worried that the same error would
be reported more than once by different subsystems. But in the ensuing
years I've seen complaints that people could not find an error log
(because this mechanism suppressed the log they were looking for).
Rip it all out. People are smart enough to notice the same address from
different reporting mechanisms.

ARM clk could only source from divcore or hsrun_divcore.
Follow what we already used on i.MX7D and i.MX8M SoCs, use
imx_clk_hw_cpu API. When ARM core is running normaly,
whether divcore or hwrun_divcore will finally source
from SPLL_PFD0. However SPLL_PFD0 is marked with CLK_SET_GATE,
so we need to disable SPLL_PFD0, when configure the rate.
So add CORE and HSRUN_CORE virtual clk to make it easy to
configure the clk using imx_clk_hw_cpu API.
Since CORE and HSRUN_CORE already marked with CLK_IS_CRITICAL, no
need to set ARM as CLK_IS_CRITICAL. And when set the rate of ARM clk,
prograting it the parent with CLK_SET_RATE_PARENT will finally set
the SPLL_PFD0 clk.

Refactoring was done to factor out the linking of DAI widgets into
a helper function, dapm_add_valid_dai_widget. However when this was
done, a regression was introduced for CODEC to CODEC links. It was
over looked that the playback and capture variables persisted across
all CODEC DAIs being processed, which ensured that the special DAI
widget that is added for CODEC to CODEC links was only created once.
This bug causes kernel panics during DAPM shutdown.
To stick with the spirit of the original refactoring whilst fixing the
issue, variables to hold the DAI widgets are added to snd_soc_dai_link.
Furthermore the dapm_add_valid_dai_widget function is renamed to
dapm_connect_dai_pair, the function only adds DAI widgets in the CODEC
to CODEC case and its primary job is to add routes connecting two DAI
widgets, making the original name quite misleading.

Add helpers for JPEG header parsing. They allow both scanning for marker
segment positions and later parsing the segments individually, as
required by s5p-jpeg, as well as parsing all headers in one go, as
required by coda-vpu. The frame header is always parsed, as basically
all decoders are interested in width, height, and number of components.
For convenience, the JPEG chroma subsampling factors are decoded into a
v4l2_jpeg_chroma_subsampling enum.
Only baseline and extended sequential DCT encoded JPEGs with 8-bit or
12-bit precision with up to four components are supported.

Thus far, accesses marked with data_race() would still require the
racing access to be marked in some way (be it with READ_ONCE(),
WRITE_ONCE(), or data_race() itself), as otherwise KCSAN would still
report a data race. This requirement, however, seems to be unintuitive,
and some valid use-cases demand *not* marking other accesses, as it
might hide more serious bugs (e.g. diagnostic reads).
Therefore, this commit changes data_race() to no longer require marking
racing accesses (although it's still recommended if possible).
The alternative would have been introducing another variant of
data_race(), however, since usage of data_race() already needs to be
carefully reasoned about, distinguishing between these cases likely adds
more complexity in the wrong place.

Introduce ASSERT_EXCLUSIVE_*_SCOPED(), which provide an intuitive
interface to use the scoped-access feature, without having to explicitly
mark the start and end of the desired scope. Basing duration of the
checks on scope avoids accidental misuse and resulting false positives,
which may be hard to debug. See added comments for usage.
The macros are implemented using __attribute__((__cleanup__(func))),
which is supported by all compilers that currently support KCSAN.
