Pull tpm updates from Jarkko Sakkinen:
"In order to split the work a bit we've aligned with David Howells more
or less that I take more hardware/firmware aligned keyring patches,
and he takes care more of the framework aligned patches.
For TPM the patches worth of highlighting are the fixes for
refcounting provided by Lino Sanfilippo and James Bottomley.
Eric B. has done a bunch obvious (but important) fixes but there's one
a bit controversial: removal of asym_tpm. It was added in 2018 when
TPM1 was already declared as insecure and world had moved on to TPM2.
I don't know how this has passed all the filters but I did not have a
chance to see the patches when they were out. I simply cannot commit
to maintaining this because it was from all angles just wrong to take
it in the first place to the mainline kernel. Nobody should use this
module really for anything.
Finally, there is a new keyring '.machine' to hold MOK keys ('Machine
Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be
set, from which kernel knows that MOK keys are kernel trusted keys and
they are populated to the machine keyring. This keyring linked to the
secondary trusted keyring, which means that can be used like any
kernel trusted keys. This keyring of course can be used to hold other
MOK'ish keys in other platforms in future"

ASoC: Updates for v5.18
Quite a quiet release for ASoC, lots of work on drivers and platforms
but nothing too groundbreaking but not much on the core itself:
- Start of moving SoF to support multiple IPC mechanisms.
- Use of NHLT ACPI table to reduce the amount of quirking required for
Intel systems.
- Some building blocks for use in forthcoming Intel AVS driver for
legacy Intel DSP firmwares.
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas

Similarly to the previous commit, use the devlink instance
lock and let it replace the vfs_lock.
nsim_esw_legacy_enable() was locked by both port lock and
vfs lock so one set of lock/unlocks goes away.

The PGID (Port Group ID) table holds port masks
for different purposes. The first 72 are reserved
for port destination masks, flood masks, and CPU
forwarding. The rest are shared between multicast,
link aggregation, and virtualization profiles. The
GLAG area is reserved to not be used by anything
else, since it is a subset of the MCAST area.
The arbiter keeps track of which entries are in
use. You can ask for a free ID or give back one
you are done using.

Due to the different definition of txbuf in NFDK comparing to NFD3,
there're no pre-allocated txbufs for xdp use in NFDK's implementation,
we just use the existed rxbuf and recycle it when xdp tx is completed.
For each packet to transmit in xdp path, we cannot use more than
`NFDK_TX_DESC_PER_SIMPLE_PKT` txbufs, one is to stash virtual address,
and another is for dma address, so currently the amount of transmitted
bytes is not accumulated. Also we borrow the last bit of virtual addr
to indicate a new transmitted packet due to address's alignment
attribution.

Add new data path. The TX is completely different, each packet
has multiple descriptor entries (between 2 and 32). TX ring is
divided into blocks 32 descriptor, and descritors of one packet
can't cross block bounds. The RX side is the same for now.
ABI version 5 or later is required. There is no support for
VLAN insertion on TX. XDP_TX action and AF_XDP zero-copy is not
implemented in NFDK path.
Changes to Jakub's work:
* Move statistics of hw_csum_tx after jumbo packet's segmentation.
* Set L3_CSUM flag to enable recaculating of L3 header checksum
in ipv4 case.
* Mark the case of TSO a packet with metadata prepended as
unsupported.

Prepare for choosing data path based on the firmware version field.
Exploit one bit from the reserved byte in the firmware version field
as the data path type. We need the firmware version right after
vNIC is allocated, so it has to be read inside nfp_net_alloc(),
callers don't have to set it afterwards.
Following patches will bring the implementation of the second data
path.

ring and fast path logic into separate files. It is basically

For modern platforms the spec explicitly states that a
SAGV block time of zero means that SAGV is not supported.
Let's extend that to all platforms. Supposedly there should
be no systems where this isn't true, and it'll allow us to:
- use the same code regardless of older vs. newer platform
- wm latencies already treat 0 as disabled, so this fits well
with other related code
- make it a bit more clear when SAGV is used vs. not
- avoid overflows from adding U32_MAX with a u16 wm0 latency value
which could cause us to miscalculate the SAGV watermarks on tgl+

Commit 6dce5aa59e0b ("PCI: xgene: Use inbound resources for setup")
killed PCIe on my XGene-1 box (a Mustang board). The machine itself
is still alive, but half of its storage (over NVMe) is gone, and the
NVMe driver just times out.
Note that this machine boots with a device tree provided by the
UEFI firmware (2016 vintage), which could well be non conformant
with the spec, hence the breakage.
With the patch reverted, the box boots 5.17-rc8 with flying colors.

Clang warns on certain 32-bit architectures:
drivers/gpu/drm/selftests/test-drm_plane_helper.c:76:5: warning: stack frame size (1064) exceeds limit (1024) in 'igt_check_plane_state' [-Wframe-larger-than]
int igt_check_plane_state(void *ignored)
^
1 warning generated.
The structures in igt_check_plane_state() total 1008 bytes, so any small
amount of inlining will cause the stack frame to exceed the 32-bit limit
of 1024, triggering the warning.
Move these structures to static storage, which dramatically reduces the
amount of stack space in igt_check_plane_state(). There is no testing
impact, as igt_check_plane_state() is only called once in the driver.
Fixes: 943e6a8beeac ("mock a drm_plane in igt_check_plane_state to make the test more robust")

The res is initialized here only if there's no errors so passing it to
ttm_resource_fini in the error paths results in a kernel oops. In the
error paths, instead of the unitialized res, we have to use to use
node->base on which ttm_resource_init was called.

Add support for the IST3038C touchscreen IC from Imagis, based on
downstream driver. The driver supports multi-touch (10 touch points)
The IST3038C IC supports touch keys, but the support isn't added
because the touch screen used for testing doesn't utilize touch keys.
Looking at the downstream driver, it is possible to add support
for other Imagis ICs of IST30**C series.
