Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.19/arm64-dt)

[1/1] arm64: dts: amlogic: meson-g12b: Fix L2 cache reference for S922X CPUs
      https://git.kernel.org/amlogic/c/79482f3791c4760b9b0d8d9bfde9f1053ea3dd5e

These changes has been applied on the intermediate git tree [1].

The v6.19/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
