💖 tvp514x_s_routing(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for tvp514x_s_routing — yes it's a mouthful, yes you're gonna slay it, and yes it's literally the V4L2 decoder interface handler for s_routing 🎀 iykyk

---

✨ SYNOPSIS ✨

int tvp514x_s_routing (struct v4l2_subdev *sd , u32 input , u32 output ,
       u32 config );

like, that's the whole signature, no cap 💅

---

🦋 ARGUMENTS 🦋

• sd — pointer to the standard V4L2 sub-device structure 🌸 standard, iconic, necessary
• input — the input selector, aka the thing that routes the signal 🎀
• output — the output selector, also for routing the signal ✨ (yes, there's two of them, it's giving full routing moment)
• config — config value. Not used. like literally not used, don't come for her 🙈

---

💜 DESCRIPTION 💜

so here's the vibe: if index is valid, it selects the requested input 🔥 simple, clean, main character energy.

Otherwise? it returns -EINVAL 😭 and that happens if the input is not supported or there's no active signal present in the selected input. so like, no input, no vibes, -EINVAL, periodt 💀

⚠️ heads up bestie: the check is index, but the argument you pass in is input. that's just what the page says, we don't question the lore 🫶
