💅 SXIRSB(4) — bestie edition ✨

sxirsb — the Allwinner Reduced Serial Bus controller, no cap ✨

🎀 SYNOPSIS 🎀

sxirsb* at fdt?

that's it. that's the whole vibe. it attaches at fdt? and minds its own business 💅

🦋 DESCRIPTION 🦋

okay so the sxirsb driver is the one that provides support for the Reduced Serial Bus (RSB for short, iykyk) controller — and this thing is integrated right onto the Allwinner A23/A33/A64/A80/A83T SoCs. iconic lineup honestly 👑

and what even is RSB? so glad you asked bestie. RSB is a two-wire bus developed by X-Powers as a high-speed alternative to I2C, and its whole job is connecting integrated circuits. like, that's the assignment. it ate and left no crumbs 🔥

typically you'll see it used for connecting devices such as power management ICs and audio codecs. very main character energy for a bus ngl 💜
