PMIC XO is the clock source for wifi rf clock in integrated wifi
chipset ex: WCN3990. Due to board layout errors XO frequency drifts
can cause wifi rf clock inaccuracy.
XO calibration test tree in Factory Test Mode is used to find the
best frequency offset(for example +/-2KHz )by programming XO trim
register. This ensure system clock stays within required 20 ppm
WLAN rf clock.
Retrieve the xo trim offset via system firmware (e.g., device tree),
especially in the case where the device doesn't have a useful EEPROM
on which to store the calibrated XO offset (e.g., for integrated Wifi).
Calibrated XO offset is sent to fw, which compensate the clock drift

The regulator_get_optional() exists for cases where the driver needs do
behave differently depending on some regulator supply being present or
not, as we don't use this we can use the standard regulator_get() and
rely on its handling of unspecified regulators.
While the driver currently doesn't specify any loads the regulator
framework was updated last year to only account for load of enabled
regulators, so should the need appear it's better to apply load numbers
during initialization that dynamically.
With this the regulator wrappers have been reduced the become identical

But while the new message adds a slew of optional members it changes the
data type of the "daemon_support" member, which means that older
versions of the firmware will fail to decode the incoming request
message.
There is no way to detect this breakage from Linux and there's no way to
recover from sending the wrong message (i.e. we can't just try one
format and then fallback to the other), so a quirk is introduced in
DeviceTree to indicate to the driver that the firmware requires the 8bit

"Last week, Palmer and I learned that there was an error in the RISC-V
kernel image header format that could make it less compatible with the
ARM64 kernel image header format. I had missed this error during my
original reviews of the patch.
The kernel image header format is an interface that impacts
bootloaders, QEMU, and other user tools. Those packages must be
updated to align with whatever is merged in the kernel. We would like
to avoid proliferating these image formats by keeping the RISC-V
header as close as possible to the existing ARM64 header. Since the
arch/riscv patch that adds support for the image header was merged
with our v5.3-rc1 pull request as commit
0f327f2aaad6a ("RISC-V: Add
an Image header that boot loader can parse."), we think it wise to try
to fix this error before v5.3 is released.
The fix itself should be backwards-compatible with any project that
has already merged support for premature versions of this interface.
It primarily involves ensuring that the RISC-V image header has
something useful in the same field as the ARM64 image header"

KVM: x86/mmu: Reintroduce fast invalidate/zap for flushing memslot
James Harvey reported a livelock that was introduced by commit
d012a06ab1d23 ("Revert "KVM: x86/mmu: Zap only the relevant pages when
removing a memslot"").
The livelock occurs because kvm_mmu_zap_all() as it exists today will
voluntarily reschedule and drop KVM's mmu_lock, which allows other vCPUs
to add shadow pages. With enough vCPUs, kvm_mmu_zap_all() can get stuck
in an infinite loop as it can never zap all pages before observing lock
contention or the need to reschedule. The equivalent of kvm_mmu_zap_all()
that was in use at the time of the reverted commit (
4e103134b8623, "KVM:
x86/mmu: Zap only the relevant pages when removing a memslot") employed
a fast invalidate mechanism and was not susceptible to the above livelock.
There are three ways to fix the livelock:
- Reverting the revert (commit
d012a06ab1d23) is not a viable option as
the revert is needed to fix a regression that occurs when the guest has
one or more assigned devices. It's unlikely we'll root cause the device
assignment regression soon enough to fix the regression timely.
- Remove the conditional reschedule from kvm_mmu_zap_all(). However, although
removing the reschedule would be a smaller code change, it's less safe
in the sense that the resulting kvm_mmu_zap_all() hasn't been used in
the wild for flushing memslots since the fast invalidate mechanism was
introduced by commit
6ca18b6950f8d ("KVM: x86: use the fast way to
invalidate all pages"), back in 2013.
- Reintroduce the fast invalidate mechanism and use it when zapping shadow
pages in response to a memslot being deleted/moved, which is what this
patch does.
For all intents and purposes, this is a revert of commit
ea145aacf4ae8
("Revert "KVM: MMU: fast invalidate all pages"") and a partial revert of
commit
7390de1e99a70 ("Revert "KVM: x86: use the fast way to invalidate
all pages""), i.e. restores the behavior of commit
5304b8d37c2a5 ("KVM:

6ca18b6950f8d ("KVM: x86:

Emulation of VMPTRST can incorrectly inject a page fault

The page fault will use uninitialized kernel stack memory

The right behavior would be to abort the VM with a KVM_EXIT_INTERNAL_ERROR

riscv: modify the Image header to improve compatibility with the ARM64 header
Part of the intention during the definition of the RISC-V kernel image
header was to lay the groundwork for a future merge with the ARM64
image header. One error during my original review was not noticing
that the RISC-V header's "magic" field was at a different size and
position than the ARM64's "magic" field. If the existing ARM64 Image
header parsing code were to attempt to parse an existing RISC-V kernel
image header format, it would see a magic number 0. This is
undesirable, since it's our intention to align as closely as possible
with the ARM64 header format. Another problem was that the original
"res3" field was not being initialized correctly to zero.
Address these issues by creating a 32-bit "magic2" field in the RISC-V
header which matches the ARM64 "magic" field. RISC-V binaries will
store "RSC\x05" in this field. The intention is that the use of the
existing 64-bit "magic" field in the RISC-V header will be deprecated
over time. Increment the minor version number of the file format to
indicate this change, and update the documentation accordingly. Fix
the assembler directives in head.S to ensure that reserved fields are
properly zero-initialized.

cdc_ether: fix rndis support for Mediatek based smartphones
A Mediatek based smartphone owner reports problems with USB

interface pair (e0/01/03 + 10/00/00), but the driver fails to
bind with
[ 355.960428] usb 1-4: bad CDC descriptors
The problem is a failsafe test intended to filter out ACM serial
functions using the same 02/02/ff class/subclass/protocol as RNDIS.
The serial functions are recognized by their non-zero bmCapabilities.
No RNDIS function with non-zero bmCapabilities were known at the time
this failsafe was added. But it turns out that some Wireless class
RNDIS functions are using the bmCapabilities field. These functions
are uniquely identified as RNDIS by their class/subclass/protocol, so
the failing test can safely be disabled. The same applies to the two
types of Misc class RNDIS functions.
Applying the failsafe to Communication class functions only retains
the original functionality, and fixes the problem for the Mediatek based
smartphone.
Tow examples of CDC functional descriptors with non-zero bmCapabilities
from Wireless class RNDIS functions are:

Similar to other fields, implement by
1. initialize the sockcm_cookie.mark from socket option sk_mark
2. optionally overwrite this in ip_cmsg_send/ip6_datagram_send_ctl
3. initialize inet_cork.mark from sockcm_cookie.mark
4. initialize each (usually just one) skb->mark from inet_cork.mark

instead of the driver accessing the queue mapping directly.
Jake updates i40e to use ktime_get_real_ts64() instead of
ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud
filters, since it is a reserved bit and not a valid type. Also added
code comments to clearly state which bits are reserved and should not be

Czeslaw also adds additional log message for devices without FEC in the

CONFIG_HEADER_TEST support and a bit of housekeeping:
8) Missing include guard in conntrack label header, from Jeremy Sowden.
9) A few coding style errors: trailing whitespace, incorrect indent in
Kconfig, and semicolons at the end of function definitions.
10) Remove unused ipt_init() and ip6t_init() declarations.
11) Inline xt_hashlimit, ebt_802_3 and xt_physdev headers. They are
only used once.
12) Update include directive in several netfilter files.
13) Remove unused include/net/netfilter/ipv6/nf_conntrack_icmpv6.h.
14) Move nf_ip6_ext_hdr() to include/linux/netfilter_ipv6.h
15) Move several synproxy structure definitions to nf_synproxy.h
16) Move nf_bridge_frag_data structure to include/linux/netfilter_bridge.h
17) Clean up static inline definitions in nf_conntrack_ecache.h.
18) Replace defined(CONFIG...) || defined(CONFIG...MODULE) with IS_ENABLED(CONFIG...).
19) Missing inline function conditional definitions based on Kconfig
preferences in synproxy and nf_conntrack_timeout.
20) Update br_nf_pre_routing_ipv6() definition.
21) Move conntrack code in linux/skbuff.h to nf_conntrack headers.
22) Several patches to remove superfluous CONFIG_NETFILTER and
CONFIG_NF_CONNTRACK checks in headers, coming from the initial batch
support for CONFIG_HEADER_TEST for netfilter.

mmc: tmio: Fixup runtime PM management during remove
Accessing the device when it may be runtime suspended is a bug, which is

mmc: tmio: Fixup runtime PM management during probe
The tmio_mmc_host_probe() calls pm_runtime_set_active() to update the
runtime PM status of the device, as to make it reflect the current status
of the HW. This works fine for most cases, but unfortunate not for all.
Especially, there is a generic problem when the device has a genpd attached
and that genpd have the ->start|stop() callbacks assigned.
More precisely, if the driver calls pm_runtime_set_active() during
->probe(), genpd does not get to invoke the ->start() callback for it,
which means the HW isn't really fully powered on. Furthermore, in the next
phase, when the device becomes runtime suspended, genpd will invoke the
->stop() callback for it, potentially leading to usage count imbalance
problems, depending on what's implemented behind the callbacks of course.
To fix this problem, convert to call pm_runtime_get_sync() from
tmio_mmc_host_probe() rather than pm_runtime_set_active(). Additionally, to
avoid bumping usage counters and unnecessary re-initializing the HW the
first time the tmio driver's ->runtime_resume() callback is called,
introduce a state flag to keeping track of this.

Revert "mmc: tmio: move runtime PM enablement to the driver implementations"
This reverts commit
7ff213193310ef8d0ee5f04f79d791210787ac2c.
It turns out that the above commit introduces other problems. For example,
calling pm_runtime_set_active() must not be done prior calling
pm_runtime_enable() as that makes it fail. This leads to additional
problems, such as clock enables being wrongly balanced.
Rather than fixing the problem on top, let's start over by doing a revert.
