💅 ca8210_spi_transfer(9) — the kernel API manual moment

okay bestie, welcome to the kernel API manual page for ca8210_spi_transfer. yes it's giving "tiny function, huge friend group" energy, and honestly? we love that for it. let's get into it ✨

🎀 NAME 🎀

ca8210_spi_transfer — bestie, this is the one that initiates a duplex spi transfer with ca8210. that's the whole vibe check. duplex, meaning both directions, no cap 💅

🌸 SYNOPSIS 🌸

int ca8210_spi_transfer (struct spi_device *spi , const u8 *buf , size_t
len );

that's the signature, copy it exactly, don't come for me about the spacing, that's literally how it's written 🫶

🦋 ARGUMENTS 🦋

  • spi — pointer to the spi device for the transfer. like, the device you're doing the transfer with, not the vibe you're doing it in ✨
  • buf — the octet array to send. an octet array. yes. bytes. bestie it's bytes 😭
  • len — the length of the buffer being sent. how much of buf we're actually sending out into the world 🌈

⭐ RETURN ⭐

0 or a linux error code. that's it. that's the tea. 0 = slay, anything else = linux error code doing its little thing 💀

💜 SEE ALSO 💜

okay so this is the part where the friend group all gets tagged in the group chat 👑. first up, the actual kernel file:

and now the whole squad, no one left out, periodt:

literally the entire ca8210 extended universe in one list, iykyk 🧚

ok and that's the page!! stay hydrated, read your kernel headers, and remember: duplex means both ways 💖

sign-off time, bestie: this little gem lives in ./drivers/net/ieee802154, and the date on it is October 2026. iconic. no notes. 🍓🔥
