Update D0 <-> D3 sequence to correctly transition hardware and DSP core
from and to D3. On top of that, set SHIM registers to their recommended
defaults during D0 and D3 proceduces as HW does not reset registers for
us.
Connected to:
[alsa-devel][BUG] bdw-rt5650 DSP boot timeout
https://mailman.alsa-project.org/pipermail/alsa-devel/2019-July/153098.html
Github issue ticket reference:
https://github.com/thesofproject/linux/pull/1842
Tested on:
- BDW-Y RVP with rt286
- SAMUS with rt5677
Proposed solution (both in July 2019 and on github):
'Revert "ASoC: Intel: Work around to fix HW d3 potential crash issue"'
is NAKed as it only covers the problem up and actually brings back the
undefined behavior: some registers (e.g.: APLLSE) are describing LPT
offsets rather than WPT ones. In consequence, during power-transitions
driver issues incorrect writes and leaves the regs of interest alone.
Existing patch - the non-revert - does not resolve the HW D3 issue at
all as it ignores the recommended sequence and does not initialize
hardware registers as expected. And thus, leaving things as are is also
unacceptable.

Major regressions were detected by SOF CI on CherryTrail and Broadwell:
[ 25.705750] SSP2-Codec: ASoC: no backend playback stream
[ 27.923378] SSP2-Codec: ASoC: no users playback at close - state
This is root-caused to the introduction of the DAI capability checks
with snd_soc_dai_stream_valid(). Its use in soc-pcm.c makes it a
requirement for all DAIs to report at least a non-zero min_channels
field.
For some reason the SSP structures used for SKL+ did provide this
information but legacy platforms didn't.

Resctrl assumes that all CPUs are online when the filesystem is mounted,
and that CPUs remember their CDP-enabled state over CPU hotplug.
This goes wrong when resctrl's CDP-enabled state changes while all the
CPUs in a domain are offline.
When a domain comes online, enable (or disable!) CDP to match resctrl's
current setting.

This patch fixes a bug when the user adds the first MAC address filter
via ethtool NFC mechanism.
When the first MAC address filter is added, it overwrites the default
MAC address filter configured at RAL[0] and RAH[0]. As consequence,
frames addressed to the interface MAC address are not sent to host
anymore.
This patch fixes the bug by calling igc_set_default_mac_filter() during
adapter init so the position 0 of adapter->mac_table[] is assigned to
the default MAC address.

This patch fixes some register overwriting when dumping registers via
ethtool.
We have a total of 16 RAL registers, starting at offset 139. So RAH
offset should be 139 + 16 = 155, not 145. As result some RAL registers
are overwritten. Likewise, RAH registers are also overwritten by TDBAL,
TDBAH, TDLEN, and TDH registers.
To fix this bug while preserving the ABI, this patch re-writes RAL and
RAH registers at the end of 'regs_buff' and bumps regs->version. It also
removes some pointless comments in the middle of igc_set_regs().

Variables declared in a switch statement before any case statements
cannot be automatically initialized with compiler instrumentation (as
they are not part of any execution flow). With GCC's proposed automatic
stack variable initialization feature, this triggers a warning (and they
don't get initialized). Clang's automatic stack variable initialization
(via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also
doesn't initialize such variables[1]. Note that these warnings (or silent
skipping) happen before the dead-store elimination optimization phase,
so even when the automatic initializations are later elided in favor of
direct initializations, the warnings remain.
To avoid these problems, move such variables into the "case" where
they're used or lift them up into the main function body.

This adds support for ETF offloading for the i225 controller.
For i225, the LaunchTime feature is almost a subset of the Qbv
feature. The main change from the i210 is that the launchtime of each
packet is specified as an offset applied to the BASET register. BASET
is automatically incremented each cycle.
For i225, the approach chosen is to re-use most of the setup used for
taprio offloading. With a few changes:
- The more or less obvious one is that when ETF is enabled, we should
set add the expected launchtime to the (advanced) transmit
descriptor;
- The less obvious, is that when taprio offloading is not enabled, we
add a dummy schedule (all queues are open all the time, with a cycle
time of 1 second).

enforcement more precise and saving CPU time.

opened and closed only once in each cycle.
Changing schedules is still not supported as well.

Partial generic segmentation offload is a hybrid between TSO and GSO.
What is effectively does is take advantage of certain traits of TCP and
tunnels so that instead of having to rewrite the packet headers for each
segment only in the inner-most transport header and possible the outer-most
network header need to be updated.
This allows devices that do not support tunnel offload or tunnels
offloads with checksum to still make use of segmentation.

Currently, after the forward channel connection goes away,
backchannel operations are causing soft lockups on the server
because call_transmit_status's SOFTCONN logic ignores ENOTCONN.
Such backchannel Calls are aggressively retried until the client
reconnects.
Backchannel Calls should use RPC_TASK_NOCONNECT rather than
RPC_TASK_SOFTCONN. If there is no forward connection, the server is
not capable of establishing a connection back to the client, thus
that backchannel request should fail before the server attempts to
send it. Commit 58255a4e3c ("NFSD: NFSv4 callback client should
use RPC_TASK_SOFTCONN") was merged several years before
RPC_TASK_NOCONNECT was available.
Because setup_callback_client() explicitly sets NOPING, the NFSv4.0
callback connection depends on the first callback RPC to initiate
a connection to the client. Thus NFSv4.0 needs to continue to use
RPC_TASK_SOFTCONN.
