max9271_configure_gmsl_link(9)

💅 max9271_configure_gmsl_link(9) — aka the GMSL link glow-up 💅

okay so bestie, welcome to the Kernel API Manual entry for max9271_configure_gmsl_link(9) — yes the whole page is named after the function, it's giving main character energy and honestly? deserved. 🎀

---

✨ NAME ✨

max9271_configure_gmsl_link — literally just: configure the GMSL link. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

int max9271_configure_gmsl_link (struct max9271_device *dev );

no cap, that's the full signature, copied exactly, don't @ me. 💅

---

✨ ARGUMENTS ✨

• dev — the max9271 device 🫶 like, the actual device struct you're handing over. that's it. that's the arg.

---

✨ DESCRIPTION ✨

so here's the tea, and I'm gonna be so fr fr with you: the GMSL link configuration is currently hardcoded and it gets done by programming registers 0x04, 0x07 and 0x02. 🔥

⚠️ and yeah, the source literally flags this with a FIXME: — so bestie, this is the "it works, don't look at it too hard" era of the driver. not me pointing at the hardcoded registers like 👀. it's giving "temporary but iconic".

and the return situation? Return 0 on success or a negative error code on failure. 😭 so like, 0 = slay, negative = we do not slay, check the code.
