tuner_s_type_addr(9)

💅 tuner_s_type_addr(9)

okay so this is a page from the Kernel API Manual, bestie — like, the tuner_s_type_addr(9) of it all. no cap, it's literally about setting the tuner type for a device ✨

---

🎀 NAME 🎀

tuner_s_type_addr — sets the tuner type for a device 🫶

---

⭐ SYNOPSIS ⭐

int tuner_s_type_addr (struct v4l2_subdev *sd , struct tuner_setup
*tun_setup );

like, it returns an int, takes a struct v4l2_subdev *sd and a struct tuner_setup *tun_setup, and that's the whole vibe 💖

---

🌸 ARGUMENTS 🌸

• sd — the subdev descriptor, aka the little guy you're operating on 🦋
• tun_setup — the type to be associated to a given tuner i2c address. iconic. that's the assignment 👑

---

👑 DESCRIPTION 👑

so this function applies the tuner config to the tuner specified by the tun_setup structure. that's it, that's the main character energy 🙈

🚨 okay here's the important bit, pay attention bestie — the behaviour is conditional and lowkey specific:

• If the tuner I2C address is UNSET, then it will only set the device if the tuner supports the mode specified in the call 🌈
• If the address is specified, the change will be applied only if the tuner I2C address matches 💀

and the call can change the tuner number and the tuner mode — two things at once, multitasking queen 💅
