52219e719f MAINTAINERS: match freescale ARM64 DT directory in i.MX entry
The majority of device trees in arch/arm64/boot/dts/freescale/ are
built around i.MX SoCs with the rest being for Layerscape. Yet, calling
get_maintainers.pl -f on this directory will not match the MAINTAINERS
entry, because the directory name doesn't contain the substring "imx".
Add an explicit file match for the directory and exclude the Layerscape
specific files. This ensures To/Cc is not only generated from git
history, but takes e.g. the R: entries into account as well.

    different controllers with different register layout (Exynos, Tesla
    FSD). Extend the bindings with missing clocks.

Given that I currently don't have spare time to invest in looking at

f5ec7f54fd drivers: misc: Add Support for TMR Manager
Triple Modular Redundancy(TMR) subsystem contains three microblaze cores,
subsystem is fault-tolerant and continues to operate nominally after
encountering an error. Together with the capability to detect and recover
from errors, the implementation ensures the reliability of the entire
subsystem.  TMR Manager is responsible for performing recovery of the
subsystem detects the fault via a break signal it invokes microblaze
software break handler which calls the tmr manager driver api to
update the error count and status, added support for fault detection
feature via sysfs interface.

Usage:
To know the break handler count(Error count):

only support for the platforms that were already converted to DT, as
well as the gumstix and spitz/akita/borzoi machines that work in qemu
and can still be converted to DT later.

35b137630f accel/ivpu: Introduce a new DRM driver for Intel VPU
VPU stands for Versatile Processing Unit and it's a CPU-integrated
inference accelerator for Computer Vision and Deep Learning
applications.

The VPU device consist of following components:
  - Buttress - provides CPU to VPU integration, interrupt, frequency and
    power management.
  - Memory Management Unit (based on ARM MMU-600) - translates VPU to
    host DMA addresses, isolates user workloads.
  - RISC based microcontroller - executes firmware that provides job
    execution API for the kernel-mode driver
  - Neural Compute Subsystem (NCS) - does the actual work, provides
    Compute and Copy engines.
  - Network on Chip (NoC) - network fabric connecting all the components

This driver supports VPU IP v2.7 integrated into Intel Meteor Lake
client CPUs (14th generation).

Module sources are at drivers/accel/ivpu and module name is
"intel_vpu.ko".

This patch includes only very besic functionality:
  - module, PCI device and IRQ initialization
  - register definitions and low level register manipulation functions
  - SET/GET_PARAM ioctls
  - power up without firmware

fs: move mnt_idmap
Now that we converted everything to just rely on struct mnt_idmap move it all
into a separate file. This ensure that no code can poke around in struct
mnt_idmap without any dedicated helpers and makes it easier to extend it in the
future. Filesystems will now not be able to conflate mount and filesystem
idmappings as they are two distinct types and require distinct helpers that
cannot be used interchangeably. We are now also able to extend struct mnt_idmap
as we see fit.

e1fabbc83c efi: Remove Matthew Garrett as efivarfs maintainer
Matthew Garrett is still listed as a efivarfs co-maintainer, but the
email address bounces, and Matt is no longer involved in maintaining
this code.

So let's remove Matt as a efivarfs co-maintainer from MAINTAINERS.
Thanks for all the hard work!
