Please describe your issue in as much detail as possible:

Please upstream Steam Deck platform drivers fully into the mainline kernel, so Steam for Linux can be used with a wider range of software. The last sign of life for upstream drivers seems to have been two entire years ago: https://www.phoronix.com/news/Steam-Deck-Platform-Driver-2024 And now there are even rumors of a Steam Deck 2 already. It would be nice to give the Steam Deck more true operating system freedom before everyone stops using it.

Steps for reproducing this issue:

1. Try to install a generic x64 system on the Steam Deck
2. Almost no Linux distribution has good support for the Steam Deck, and those which do seem to use some weird custom kernel

This might also be a hardware longevity issue, since apparently the Steam Deck is prone to battery bloating unless the charging is reduced to 70% max. This appears to be however not possible with the mainline kernel right now, since the /sys interface part that would allow KDE & GNOME's system settings to set the charging range appears to require the missing platform driver.
