The differences between register fields on different SoC versions
can be abstracted away using the regmap field API. This is easier
to understand and extend than comparisons based on the version ID.
Since the version IDs are unused after this change, remove them at
the same time, and remove unused macros.

Using regmap for accessing the AIC registers makes the driver a
little easier to read, and later refactors can take advantage of
regmap APIs to further simplify the driver.

On the JZ4740, there is a single bit that flushes (empties) both
the transmit and receive FIFO. Later SoCs have independent flush
bits for each FIFO.
Independent FIFOs can be flushed before the snd_soc_dai_active()
check because it won't disturb other active streams. This ensures
that the FIFO we're about to use is always flushed before starting
up. With shared FIFOs we can't do that because if another substream
is active, flushing its FIFO would cause underrun errors.
This also fixes a bug: since we were only setting the JZ4740's
flush bit, which corresponds to the TX FIFO flush bit on other
SoCs, other SoCs were not having their RX FIFO flushed at all.

Remove the last usage of substream->runtime->private_data in the

The SOF HDAudio code stores the Host DMA hdac_stream structure in the
FE substream->runtime->private_data. The BE dailink also uses the
substream->runtime->private_data to allocate the link DMA stream tag.
This really works by accident: the DPCM core copies the FE runtime
information in the BE, which has the side-effect of sharing the
FE-specific private_data with the BE.
To avoid more uses of the private_data with potential issues such as
accessing stale information or use-after-free cases, this patch
removes most of the usages of this private_data at the BE level. We
can directly use the existing dma_data to access the relevant
information.
However the hw_params still uses the information, mainly to go back to
the 'bus' structure required for the link dma stream tag
allocation. This is safe in that the 'bus' is not stream or PCM
specific.
The next patch will completely remove this last use of private_data by
using the component_drvdata - which is how SOF passes a global context
around.

Returning an error when a read/write is not implemented makes no
sense, especially on read where no return value makes sense.
Change the logic to directly fallback to mmio. If a platform truly
wants other read/writes that are not plain vanilla mmio, it needs to

The channel-subsystem-driver scans for newly available devices whenever
device-IDs are removed from the cio_ignore list using a command such as:
echo free >/proc/cio_ignore
Since an I/O device scan might interfer with running I/Os, commit
172da89ed0ea ("s390/cio: avoid excessive path-verification requests")
introduced an optimization to exclude online devices from the scan.
The newly added check for online devices incorrectly assumes that
an I/O-subchannel's drvdata points to a struct io_subchannel_private.
For devices that are bound to a non-default I/O subchannel driver, such
as the vfio_ccw driver, this results in an out-of-bounds read access
during each scan.
Fix this by changing the scan logic to rely on a driver-independent
online indication. For this we can use struct subchannel->config.ena,
which is the driver's requested subchannel-enabled state. Since I/Os
can only be started on enabled subchannels, this matches the intent
of the original optimization of not scanning devices where I/O might
be running.

in the _DEP dependency list of the ACPI devices for the camera-sensors

The _DDN for the LATT2021 device is "Lattice FW Update Client Driver",
suggesting that this is used for firmware updates of something. There
is no Linux driver for this and if Linux gets support for updates it
will likely be in userspace through fwupd.
For now add the LATT2021 HID to acpi_ignore_dep_ids[] so that

Maybe "-Os" prevents GCC from detecting that the key/branch arguments
can be treated as constants and used as immediate operands. Inspired
by x86's commit 864b435514b2("x86/jump_label: Mark arguments as const to
satisfy asm constraints"), and as pointed out by Steven: "The "i"
constraint needs to be a constant.", let's do similar modifications to
riscv.
Tested by CC_OPTIMIZE_FOR_SIZE + gcc and CC_OPTIMIZE_FOR_SIZE + clang.

IPA v3.1 doesn't support the IDLE_INDICATION_CFG register, this was
causing a harmless splat in ipa_idle_indication_cfg(), add a version
check to prevent trying to fetch this register on v3.1

The resource group limits for IPA v3.1 mistakenly used 6 bit wide mask
values, when the hardware actually uses 8. Out of range values were
silently ignored before, so the IPA worked as expected. However the
new generalised register definitions introduce stricter checking here,
they now cause some splats and result in the value 0 being written
instead. Fix the limit bitmask widths so that the correct values can be
written.

Some resource limits on IPA v3.5.1 have their max values set to
255, this causes a few splats in ipa_reg_encode and prevents the
IPA from booting properly. The limits are all 6 bits wide so
adjust the max values to 63.

Fix setting bits for specific flow_type for GLQF_HASH_INSET register.
In previous version all of the bits were set only in hena register, while
in inset only one bit was set. In order for this working correctly on all
types of cards these bits needs to be set correctly for both hena and inset
registers.

When a reset was triggered on one VF with i40e_reset_vf
global PF state __I40E_VF_DISABLE was set on a PF until
the reset finished. If immediately after triggering reset
on one VF there is a request to reset on another
it will cause a hang on VF side because VF will be notified
of incoming reset but the reset will never happen because
of this global state, we will get such error message:
[ +4.890195] iavf 0000:86:02.1: Never saw reset
and VF will hang waiting for the reset to be triggered.
Fix this by introducing new VF state I40E_VF_STATE_RESETTING
that will be set on a VF if it is currently resetting instead of
the global __I40E_VF_DISABLE PF state.

When enabling flow type for RSS hash via ethtool:
ethtool -N $pf rx-flow-hash tcp4|tcp6|udp4|udp6 s|d
the driver would fail to setup this setting on X722
device since it was using the mask on the register
dedicated for X710 devices.
Apply a different mask on the register when setting the
RSS hash for the X722 device.
When displaying the flow types enabled via ethtool:
ethtool -n $pf rx-flow-hash tcp4|tcp6|udp4|udp6
the driver would print wrong values for X722 device.
Fix this issue by testing masks for X722 device in
i40e_get_rss_hash_opts function.

Another syzbot report [1] with no reproducer hints
at a bug in ip6_gre tunnel (dev:ip6gretap0)
Since ipv6 mcast code makes sure to read dev->mtu once
and applies a sanity check on it (see commit b9b312a7a451
"ipv6: mcast: better catch silly mtu values"), a remaining
possibility is that a layer is able to set dev->mtu to
an underflowed value (high order bit set).
This could happen indeed in ip6gre_tnl_link_config_route(),
ip6_tnl_link_config() and ipip6_tunnel_bind_dev()
Make sure to sanitize mtu value in a local variable before
it is written once on dev->mtu, as lockless readers could
catch wrong temporary value.
