snd_soc_comp...t_read_field(9)

💅 snd_soc_comp...t_read_field(9) — like, the Kernel API Manual page, bestie ✨

Okay so you found your way into the kernel docs, and this one lives in the Kernel API Manual. Buckle up, it's a short one but it slaps.

---

🌸 NAME 🌸

snd_soc_component_read_field — literally reads a register field value for you. That's the whole job. Iconic, honestly.

---

✨ SYNOPSIS ✨

unsigned int snd_soc_component_read_field (struct snd_soc_component
*component , unsigned int reg , unsigned int mask );

Note the return type, bestie: unsigned int. Not int, not void, unsigned int. The way that matters 🫶

---

🎀 ARGUMENTS 🎀

• component — the component you're reading from 💖 like, which chip are we snooping on
• reg — the register you wanna read. the address. the location 👑
• mask — the mask of the register field. this is the "which bits do I actually care about" vibe check 🔥

---

🦋 RETURN 🦋

It gives you back the read value of the register field. That's it. That's the tea. ⭐

---

🌈 SEE ALSO 🌈

Bestie, go read the actual source first: ./sound/soc/soc-component.c — that's where the magic happens, no cap.

And then the whole friend group of related calls, all of them, in order, because I would never leave one out:

• snd_soc_component_set_sysclk(9)
• snd_soc_component_set_jack(9)
• snd_soc_component_get_jack_type(9)
• snd_soc_component_init_regmap(9)
• snd_soc_component_exit_regmap(9)
• snd_soc_component_read(9)
• snd_soc_component_write(9)

• snd_soc_component_update_bits_async(9)
• snd_soc_component_write_field(9)
• snd_soc_component_async_complete(9)
• snd_soc_component_test_bits(9)

Lowkey the whole read_field / write_field duo is giving main character energy in soc-component.c. Go look at them together. Iykyk 💅

Sign-off time, bestie 🧚 this page ships out of ./sound/soc, dated October 2026, and it's page snd_soc_comp...t_read_field(9) of the Kernel API Manual. Mwah. 💜🎀🍓
