This reverts commit c7dacf5b0f32957b24ef29df1207dc2cd8307743,
"mailbox: avoid timer start from callback"
The previous commit was reverted since it lead to a race that
caused the hrtimer to not be started at all. The check for
hrtimer_active() in msg_submit() will return true if the
callback function txdone_hrtimer() is currently running. This
function could return HRTIMER_NORESTART and then the timer
will not be restarted, and also msg_submit() will not start
the timer. This will lead to a message actually being submitted
but no timer will start to check for its compleation.
The original fix that added checking hrtimer_active() was added to
avoid a warning with hrtimer_forward. Looking in the kernel
another solution to avoid this warning is to check hrtimer_is_queued()
before calling hrtimer_forward_now() instead. This however requires a
lock so the timer is not started by msg_submit() inbetween this check
and the hrtimer_forward() call.

Resources needed for output poll workers are destroyed in
nouveau_fbcon_fini() before output poll workers are cleared in
nouveau_display_fini(). This means there is a time between fbcon_fini()
and display_fini(), where if output poll happens, it crashes.
This patch introduces another output poll clearing before fbcon
resources are destroyed.

The NXP Cryptographic Acceleration and Assurance Module (CAAM)
can be used to protect user-defined data across system reboot:
- When the system is fused and boots into secure state, the master
key is a unique never-disclosed device-specific key
- random key is encrypted by key derived from master key
- data is encrypted using the random key
- encrypted data and its encrypted random key are stored alongside
- This blob can now be safely stored in non-volatile memory
On next power-on:
- blob is loaded into CAAM
- CAAM writes decrypted data either into memory or key register
Add functions to realize encrypting and decrypting into memory alongside
the CAAM driver.
They will be used in a later commit as a source for the trusted key
seal/unseal mechanism.

Depending on SoC variant, a CAAM may be available, but with some futures
fused out. The LS1028A (non-E) SoC is one such SoC and while it
indicates BLOB support, BLOB operations will ultimately fail, because
there is no AES support. Add a new blob_present member to reflect
whether both BLOB support and the AES support it depends on is
available.
These will be used in a follow-up commit to allow blob driver
initialization to error out on SoCs without the necessary hardware
support instead of failing at runtime with a cryptic

Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.
As tpm_cr50_i2c_remove() emits an error message already and the
additional error message by the i2c core doesn't add any useful
information, change the return value to zero to suppress this error
message.
Note that if i2c_clientdata is NULL, there is something really fishy.
Assuming no memory corruption happened (then all bets are lost anyhow),
tpm_cr50_i2c_remove() is only called after tpm_cr50_i2c_probe() returned

device isn't removed. If after that happened userspace accesses the

Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't make
a difference. The device goes away anyhow and the devm cleanups are
called.
So instead of triggering the generic i2c error message, emit a more helpful
message if a problem occurs and return 0 to suppress the generic message.
This patch is a preparation for making i2c remove callbacks return void.

ASoC: Updates for v5.19
This is quite a big update, partly due to the addition of some larger
drivers (more of which is to follow since at least the AVS driver is
still a work in progress) and partly due to Charles' work sorting out
our handling of endianness. As has been the case recently it's much
more about drivers than the core.
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs.
- Initial stages of Intel AVS driver merge.
- Introduction of v4 IPC mechanism for SOF.
- TDM mode support for AK4613.
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780

Give block_size()/block_offset() a "raw_" prefix since they
both operate on the "raw" (as in not duplicated) BDB block
contents.
What actually spurred this was a conflict between intel_bios.c
block_size() vs. block_size() from blkdev.h. That only
happened to me on a custom tree where we somehow manage to
include blkdev.h into intel_bios.c. But I think the rename
makes sense anyway to clarify the purpose of these functions.

The SPI core always reports a "MODALIAS=spi:<foo>", even if the device was
registered via OF. This means that the st7735r.ko module won't autoload if
a DT has a node with a compatible "okaya,rh128128t" string.
In that case, kmod expects a "MODALIAS=of:N*T*Cokaya,rh128128t" uevent but
instead will get a "MODALIAS=spi:rh128128t", which is not present in the
list of aliases:

In commit 19cf41b64e3b ("lontium-lt9611: check a different
register bit for HDMI sensing"), the bit flag used to detect
HDMI cable connect was switched from BIT(2) to BIT(0) to improve
compatibility with some monitors that didn't seem to set BIT(2).
However, with that change, I've seen occasional issues where the
detection failed, because BIT(2) was set, but not BIT(0).
Unfortunately, as I understand it, the bits and their function
was never clearly documented. So lets instead check both
(BIT(2) | BIT(0)) when checking the register.

Update the VCAP filters to support multiple tag_8021q CPU ports.
TX works using a filter for VLAN ID on the ingress of the CPU port, with
a redirect and a VLAN pop action. This can be updated trivially by
amending the ingress port mask of this rule to match on all tag_8021q
CPU ports.
RX works using a filter for ingress port on the egress of the CPU port,
with a VLAN push action. Here we need to replicate these filters for
each tag_8021q CPU port, and let them all have the same action.
This means that the OCELOT_VCAP_ES0_TAG_8021Q_RXVLAN() cookie needs to
encode a unique value for every {user port, CPU port} pair it's given.
Do this by encoding the CPU port in the upper 16 bits of the cookie, and
the user port in the lower 16 bits.

There is a desire for the felix driver to gain support for multiple
tag_8021q CPU ports, but the current model prevents it.
This is because ocelot_apply_bridge_fwd_mask() only takes into
consideration whether a port is a tag_8021q CPU port, but not whose CPU
port it is.
We need a model where we can have a direct affinity between an ocelot
port and a tag_8021q CPU port. This serves as the basis for multiple CPU
ports.
Declare a "dsa_8021q_cpu" backpointer in struct ocelot_port which
encodes that affinity. Repurpose the "ocelot_set_dsa_8021q_cpu" API to
"ocelot_assign_dsa_8021q_cpu" to express the change of paradigm.
Note that this change makes the first practical use of the new
ocelot_port->index field in ocelot_port_unassign_dsa_8021q_cpu(), where
we need to remove the old tag_8021q CPU port from the reserved VLAN range.

Add more logic to ocelot_port_{,un}set_dsa_8021q_cpu() from the ocelot
switch lib by encapsulating the ocelot_apply_bridge_fwd_mask() call that
felix used to have.
This is necessary because the CPU port change procedure will also need
to do this, and it's good to reduce code duplication by having an entry
point in the ocelot switch lib that does all that is needed.

PGID_CPU must be updated every time a port is configured or unconfigured
as a tag_8021q CPU port. The ocelot switch lib already has a hook for
that operation, so move the updating of PGID_CPU to those hooks.
These bits are pretty specific to DSA, so normally I would keep them out
of the common switch lib, but when tag_8021q is in use, this has
implications upon the forwarding mask determined by
ocelot_apply_bridge_fwd_mask() and called extensively by the switch lib.

PGID_BC is configured statically by ocelot_init() to flood towards the
CPU port module, and dynamically by ocelot_port_set_bcast_flood()
towards all user ports.
When the tagging protocol changes, the intention is to turn off flooding
towards the old pipe towards the host, and to turn it on towards the new
pipe.
Due to a recent change which removed the adjustment of PGID_BC from
felix_set_host_flood(), 3 things happen.
- when we change from NPI to tag_8021q mode: in this mode, the CPU port
module is accessed via registers, and used to read PTP packets with
timestamps. We fail to disable broadcast flooding towards the CPU port
module, and to enable broadcast flooding towards the physical port
that serves as a DSA tag_8021q CPU port.
- from tag_8021q to NPI mode: in this mode, the CPU port module is
redirected to a physical port. We fail to disable broadcast flooding
towards the physical tag_8021q CPU port, and to enable it towards the
CPU port module at ocelot->num_phys_ports.
- when the ports are put in promiscuous mode, we also fail to update
PGID_BC towards the host pipe of the current protocol.
First issue means that felix_check_xtr_pkt() has to do extra work,
because it will not see only PTP packets, but also broadcasts. It needs
to dequeue these packets just to drop them.
Third issue is inconsequential, since PGID_BC is allocated from the
nonreserved multicast PGID space, and these PGIDs are conveniently
initialized to 0x7f (i.e. flood towards all ports except the CPU port
module). Broadcasts reach the NPI port via ocelot_init(), and reach the
tag_8021q CPU port via the hardware defaults.
Second issue is also inconsequential, because we fail both at disabling
and at enabling broadcast flooding on a port, so the defaults mentioned
above are preserved, and they are fine except for the performance impact.

The VBT send packet port selection was never updated for ICL+ where the
2nd link is on port B instead of port C as in VLV+ DSI.
First, single link DSI needs to use the configured port instead of
relying on the VBT sequence block port. Remove the hard-coded port C
check here and make it generic. For reference, see commit f915084edc5a
("drm/i915: Changes related to the sequence port no for") for the
original VLV specific fix.
Second, the sequence block port number is either 0 or 1, where 1
indicates the 2nd link. Remove the hard-coded port C here for 2nd
link. (This could be a "find second set bit" on DSI ports, but just
check the two possible options.)
Third, sanity check the result with a warning to avoid a NULL pointer
dereference.
