🌸 NAME 🌸

sxisid — Allwinner security ID

like, that's it. that's the whole name. the driver is called sxisid and what it does is handle the Allwinner security ID situation. iconic, lowkey 🎀

✨ SYNOPSIS ✨

sxisid* at fdt?

that's the whole config line, no cap. the * means it can be attached at any unit number, at fdt? means it hangs off the flattened device tree, and the ? on the end means it's optional — it might be there, it might not, vibe check 🦋

💅 DESCRIPTION 💅

so here's the tea: the sxisid driver provides support for reading the on-chip eFuses integrated on various Allwinner SoCs.

eFuses, if you were wondering — those are little one-time-programmable bits baked right into the chip. the driver's whole job is letting you read them. that's it. that's the function. she reads, she slays, she does not write 🌈

also important: this works on various Allwinner SoCs, not just one. plural. multiple. a whole roster of them 💜
