🌸 NAME 🌸

syscon — System controller. yep, that’s the whole name section, and it ate. ✨

🎀 SYNOPSIS 🎀

syscon* at fdt?

💅 DESCRIPTION 💅

so the syscon driver is literally the friend who holds everyone’s stuff: it provides access to a set of miscellaneous hardware registers to other device drivers. 🎒✨

it may also provide system reset and power off functionality — but only if such functionality is provided through hardware registers in such a set. that conditional is doing a lot of work, so keep it close. 🔥
