842912c42e arm64: dts: imx8mm: don't assign PLL2 in SoC dtsi
The base i.MX8MM dtsi changes the audio PLL2 rate, which gets in the
way if it should be used for anything else than audio. As this PLL doesn't
seem to be used by any upstream supported board, just remove the rate
configuration to allow boards to set it up as they wish.

The pinctrl that describes the gpio that is used in 2 places here is added

sure this will work.

When we would have put the same pinctrl property into the 2 regulator nodes

with flash device, it is need to add delay between CS and CLK signal.
The strategy of generating delay value refers to QorIQ LS1043A
Reference Manual.

b70bf26a70 arm64: dts: freescale: add 'chassis-type' property
A new 'chassis-type' root node property has recently been approved for
the device-tree specification, in order to provide a simple way for
userspace to detect the device form factor and adjust their behavior
accordingly.

This patch fills in this property for end-user devices (such as laptops,
smartphones and tablets) based on NXP ARM64 processors.

dee2b702bc kconfig: Add support for -Wimplicit-fallthrough
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. :)

Merge tag 'xfs-5.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

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"
