✨ SYNOPSIS ✨

the signature is literally this, character for character, no cap:

int versal_pm_aes_key_write (const u32 keylen , const u32 keysrc , const
       u64 keyaddr );

🎀 ARGUMENTS 🎀

• keylen — Size of the input key to be written. Like, the size of the key we're writing, periodt. ✨
• keysrc — Key Source to be selected to which provided key should be updated. So you're choosing the Key Source that the provided key should be updated to, iykyk. 🎯
