💅 csi_set_link_cfg — like, the Kernel API Manual page you actually wanna read 💅

okay so bestie, this is a page straight outta the Kernel API Manual, and it's all about programming the default CSI-2 link parameters. yes, that's the whole vibe. slay. ✨

✨ NAME ✨

csi_set_link_cfg — program default CSI-2 link parameters 🎀

---

🦋 SYNOPSIS 🦋

int csi_set_link_cfg (struct icvs *ctx , u64 link_freq );

---

🌸 ARGUMENTS 🌸

• ctx — the CVS device context, aka the whole personality of the device you're talking to 💖
• link_freq — the link frequency, in Hz. yes, hertz. numbers. iconic. 🔥

---

👑 DESCRIPTION 👑

so here's the tea: this function populates a HOST_SET_MIPI_CONFIG command using the current lane count and the link frequency, and then submits it to the device. that's it, that's the whole job. no cap. 🫶

and the rest of the link parameters? they're just gonna chill at the firmware defaults, left completely alone. lowkey respectful of their boundaries, honestly. 🙈 ⭐

---

💀 RETURN 💀

0 on success, or a negative errno. that's the vibe check — zero means we ate, negative means we did not eat 😭
