Update Kernel on Scarthgap (DSI + eMMC issues)

[berkutta]

I have encountered issues with DSI (Raspberry Pi 7" Display) and eMMC (kernel hang during reboot) when using Yocto Scarthgap on a CM4 with the kernel version 6.6.22.

These issues were resolved by targeting the latest Raspberry Pi kernel. I am currently using a .bbappend file with the following configuration:

LINUX_VERSION = "6.6.70"

SRCREV_machine = "dfff38316c1284c30c68d02cc424bad0562cf253"

My question is:
Is it acceptable to update the kernel to version 6.6.70 within this meta layer on Scarthgap (and potentially future Yocto releases) to avoid these issues for other users?
Or is there a specific reason why Scarthgap still uses version 6.6.22?

I think upgrading to 6.6.70 is ok, just make sure that if there are corresponding firmware changes then bring them in too
