The json-schema bindings for SRAM expect the nodes to be called "sram"
rather than "sysram" or "shmem". Furthermore, place the brackets around
the SYSRAM references such that a two-element array is created rather
than a two-element array nested in a single-element array. This is not
relevant for device tree itself, but allows the nodes to be properly
validated against json-schema bindings.

controllers found on Tegra234 and add some memory client and SMMU

The #interconnect-cells properties are required to hook up memory
clients to the MC/EMC in interconnects properties. Add a description for
these properties.

For the nested EMC controller, the list of required properties was
missing. Add it so that the validation can be more strict.

Also, allow multiple reg entries required by Tegra194 and later.

While at it, also remove the dummy BPMP node from the example because it
is incomplete and fails validation. It's also not necessary for this
file and the BPMP DT schema already has a full example.

Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang.

The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH,
which is enabled by default.

Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This
bugfix only appears in Clang 14.0.0, so older versions still contain
the bug and -Wimplicit-fallthrough won't be enabled for them, for now.

This concludes a long journey and now we are finally getting rid
of the unintentional fallthrough bug-class in the kernel, entirely. :)

Pull xfs cleanups from Darrick Wong:
 "The most 'exciting' aspect of this branch is that the xfsprogs
  maintainer and I have worked through the last of the code
  discrepancies between kernel and userspace libxfs such that there are
  no code differences between the two except for #includes.

  IOWs, diff suffices to demonstrate that the userspace tools behave the
  same as the kernel, and kernel-only bits are clearly marked in the
  /kernel/ source code instead of just the userspace source.

  Summary:

   - Clean up open-coded swap() calls.

   - A little bit of #ifdef golf to complete the reunification of the
     kernel and userspace libxfs source code"
