Any schedule for LSDK 22.xx available? Update to Linux kernel 5.15?

[feelfree]

We are currently developing a product with LX2160. We use the linux kernel 5.10 from the current LSDK 2108 release.
Questions:
Are there any plans to update to kernel 5.15 with the next LSDK release?
Is there an estimated release date for the next LSDK 22.xx release?

Thanks for your response!

I'm afraid now I'm a bit confused about NXP's maintained Linux kernel repos:
Under https://source.codeaurora.org/external/qoriq/qoriq-components/linux there exist branches for
- linux-5.10
- lf-5.10.y
- lf-5.15.y
-and the respective -rt variants

I assume the ".y" stands for yocto, wheres the "linux-5.10" branch is the one being used in LSDK.
How do the kernel repos linux-5.xx and lf-5.xx differ from each other and which one is being recommended? Or doesn't it matter?

The branch lf-5.15.y  is recommended to use, it is from the latest Linux Factory LTS 5.15 release.
