e3dcb725a9 pinctrl: Convert Allwinner Pin Controller to a schema 
The Allwinner SoCs have a pin controller supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

8298d18a49 pinctrl: bcm: nsp: use gpiolib infrastructure for interrupts 
Use more of the gpiolib infrastructure for handling interrupts. The
root interrupt still needs to be handled manually as it is shared with
other peripherals on the SoC.

This will allow multiple instances of this driver to be supported and
will clean up gracefully on failure thanks to the device managed APIs.

f23c7ce341 Merge branch 'bpf-libbpf-bitfield-size-relo' 
Andrii Nakryiko says:

====================
This patch set adds support for reading bitfields in a relocatable manner
through a set of relocations emitted by Clang, corresponding libbpf support
for those relocations, as well as abstracting details into
BPF_CORE_READ_BITFIELD/BPF_CORE_READ_BITFIELD_PROBED macro.

We also add support for capturing relocatable field size, so that BPF program
code can adjust its logic to actual amount of data it needs to operate on,
even if it changes between kernels. New convenience macro is added to
bpf_core_read.h (bpf_core_field_size(), in the same family of macro as
bpf_core_read() and bpf_core_field_exists()). Corresponding set of selftests
are added to excercise this logic and validate correctness in a variety of
scenarios.

Some of the overly strict logic of matching fields is relaxed to support wider
variety of scenarios. See patch #1 for that.

Patch #1 removes few overly strict test cases.
Patch #2 adds support for bitfield-related relocations.
Patch #3 adds some further adjustments to support generic field size
relocations and introduces bpf_core_field_size() macro.
Patch #4 tests bitfield reading.
Patch #5 tests field size relocations.

v1 -> v2:
  - added direct memory read-based macro and tests for bitfield reads.

bdc62f2bae usb: typec: ucsi: Simplified registration and I/O API 
Adding more simplified API for interface registration and
read and write operations.

The registration is split into separate creation and
registration phases. That allows the drivers to properly
initialize the interface before registering it if necessary.

The read and write operations are supplied in a completely
separate struct ucsi_operations that is passed to the
ucsi_register() function during registration. The new read
and write operations will work more traditionally so that
the read callback function reads a requested amount of data
from an offset, and the write callback functions write the
given data to the offset. The drivers will have to support
both non-blocking writing and blocking writing. In blocking
writing the driver itself is responsible of waiting for the
completion event.

The new API makes it possible for the drivers to perform
tasks also independently of the core ucsi.c, and that should
allow for example quirks to be handled completely in the
drivers without the need to touch ucsi.c.

The old API is kept until all drivers have been converted to
the new API.

7a42d41d9d x86/vmlinux: Restore "text" Program Header with dummy section 
In a linker script, if one places a section in one or more segments using
":PHDR", then the linker will place all subsequent allocatable sections,
which do not specify ":PHDR", into the same segments. In order to have
the NOTES section in both PT_LOAD (":text") and PT_NOTE (":note"), both
segments are marked, and the only way to undo this to keep subsequent
sections out of PT_NOTE is to mark the following section with just the
single desired PT_LOAD (":text").

In preparation for having a common NOTES macro, perform the segment
assignment using a dummy section (as done by other architectures).
