The TA_PROG_SFP supply must be enabled to program the fuses, and
disabled to read the fuses (such as at power-on-reset). On many boards,
this supply is controlled by a jumper. The user must manually insert or
remove it at the appropriate time in the programming process. However,
on other boards this supply is controlled by an FPGA or a GPIO. In
these cases, the driver can automatically enable and disable it as
necessary.

To program fuses, it is necessary to set the fuse programming time. This
is determined based on the value of the platform clock. Add a clock
property.
Because this property is necessary for programming, it is made
mandatory. Since these bindings have not yet been present in a stable
release (though they are on track for 5.18), it is not an ABI break to
change them in this manner.

Converting binder_debug() and binder_user_error() macros into functions
reduces the overall object size by 16936 bytes when cross-compiled with
aarch64-linux-gnu-gcc 11.2.0:
$ size drivers/android/binder.o.{old,new}
text data bss dec hex filename
77935 6168 20264 104367 197af drivers/android/binder.o.old
65551 1616 20264 87431 15587 drivers/android/binder.o.new
This is particularly beneficial to functions binder_transaction() and
binder_thread_write() which repeatedly use these macros and are both
part of the critical path for all binder transactions.
$ nm --size vmlinux.{old,new} |grep ' binder_transaction$'

Provide a userspace mechanism to pull precise error information upon
failed operations. Extending the current error codes returned by the
interfaces allows userspace to better determine the course of action.
This could be for instance, retrying a failed transaction at a later
point and thus offloading the error handling from the driver.

Add the Device Feature List (DFL) feature id for the
High Speed Serial Interface (HSSI) Subsystem to the
table of ids supported by the uio_dfl driver.
The HSSI Subsystem is a configurable set of IP blocks
to be used as part of a Ethernet or PCS/FEC/PMA pipeline.
Like the Ethernet group used by the N3000 card, the HSSI
Subsystem does not fully implement a network device from
a Linux netdev perspective and is controlled and monitored
from user space software via the uio interface.
The Feature ID table of DFL can be found:

ceph: remove incorrect session state check
ceph: get snap_rwsem read lock in handle_cap_export for ceph_add_cap
libceph: disambiguate cluster/pool full log message
This reverts commit 0dc23d1a8e, which caused another regression
as the pinctrl code actually expects an integer value of 0 or 1
rather than a simple boolean property.

Synthesizing AMD leaves up to 0x80000021 caused problems with QEMU,
which assumes the *host* CPUID[0x80000000].EAX is higher or equal
to what KVM_GET_SUPPORTED_CPUID reports.
This causes QEMU to issue bogus host CPUIDs when preparing the input
to KVM_SET_CPUID2. It can even get into an infinite loop, which is
only terminated by an abort():
cpuid_data is full, no space for cpuid(eax:0x8000001d,ecx:0x3e)
To work around this, only synthesize those leaves if 0x8000001d exists
on the host. The synthetic 0x80000021 leaf is mostly useful on Zen2,
which satisfies the condition.

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Fix Intel PT (Processor Trace) timeless decoding with perf.data
directory.
- ARM SPE (Statistical Profiling Extensions) address fixes, for
synthesized events and for SPE events with physical addresses. Add a
simple 'perf test' entry to make sure this doesn't regress.
- Remove arch specific processing of kallsyms data to fixup symbol end
address, fixing excessive memory consumption in the annotation code.

- A fix to properly ensure a single CPU is running during patch_text().
- A defconfig update to include RPMSG_CTRL when RPMSG_CHAR was set,
necessary after a recent refactoring.
