Sadly no display, nobody cared enough to enable it in the original BL, but hey, at least the eMMC isn't suicidal..

This was my solution which also covers pm8841 and pma8084 https://github.com/z3ntu/lk2nd/commit/5e147f7056ee0b080a5e224c68de6927a212288a

WHy not have separate structs for each?

[z3ntu]

If you mean pma8084 vs pm8941, you'd need to query the pmic id from smem and choose the correct struct based on that - which is more complicated.

lk already does this (parse smem etc)

Sorry, this PR got a bit stale... Lately we were trying to refactor lk2nd so I'm not sure if this change is still relevant thus I'm closing it. If you want to respin it, please feel free to reopen or re-target to the experimental-tmp2 branch.
