💅 cdns_i2c_clear_bus_hold(9) — from the Kernel API Manual, bestie 🫶

okay so this one's from the Kernel API Manual (section 9, kernel internals, you know the drill) and it's honestly such a simple little function but it's important, so let's get into it ✨

🌸 NAME 🌸

cdns_i2c_clear_bus_hold — clears the bus hold bit. that's it. that's the whole job. iconic minimalism honestly 👑

✨ SYNOPSIS ✨

void cdns_i2c_clear_bus_hold (struct cdns_i2c *id );

it returns void, so like… nothing comes back. no return value, no drama, no "did it work?" — it just does the thing 💅

🎀 ARGUMENTS 🎀

  • id — pointer to the driver data struct. that's your struct cdns_i2c *, the main character of this whole file, holding all the driver's state 🧚
ngl there's exactly one argument and it's the pointer to the driver data struct, so don't overthink it 💖

🦋 DESCRIPTION 🦋

so the manpage says it plain: this is a helper whose whole purpose in life is to clear the controller's bus hold bit ✨

that's it!! it's a tiny helper function, not a headline act, but every I2C bus that needs un-holding is gonna be so grateful 😭 it's giving "small role, huge impact" energy fr fr 🌈

🔥 SEE ALSO 🔥

the kernel file this lives in is ./drivers/i2c/busses/i2c-cadence.c — go read it, it's a whole vibe 📖

and here's the full friend group, all in section 9, no cap:

like, that's the entire Cadence I2C squad right there 😤 all of them, accounted for, none skipped 🫶

okay that's the whole page bestie!! 🎀 big love to the source at ./drivers/i2c/busses, dated October 2026 — mwah, thanks for the lore, see u in the next manpage 💜🍓
