I had these patches in my testing tree for a while now. The vendor
kernel uses the same configuration, so it probably makes sense to
use them upstream as well.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (for-next)
[1/2] ARM: dts: meson8: Add more L2 (PL310) cache properties
https://git.kernel.org/amlogic/c/12cdc236cf83eb55560f52dd378f05d5798452ba

These changes has been applied on the intermediate git tree [1].
The for-next 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.
