No, the "fix" is scheduled to go into v5.7 kernel as well. It is here:

git://git.kernel.org/pub/scm/linux/kernel/git/kristo/linux tags/ti-k3-soc-for-v5.7

This is already part of ARM SoC tree, and slated for v5.7

https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc.git/log/?h=arm/dt

Arnd, Olof,

Can you please help by either queuing the arm/dt entirely or just the K3 SoC
parts to Linus sooner than later?

Thanks,
Sekhar
