💖 ks8851_rdreg — the "just read the register already" girlies 💖

okay so this is a page from the Kernel API Manual, bestie — it's ks8851_rdreg(9) and she's lowkey iconic. no cap, she's the one who actually goes and fetches the register data for you. 🦋

✨ NAME ✨

ks8851_rdreg — issue read register command and return the data 💅

🎀 SYNOPSIS 🎀

void ks8851_rdreg (struct ks8851_net *ks , unsigned int op , u8 *rxb ,
unsigned int rxl );

🌸 ARGUMENTS 🌸

  • ks — The device state. it's giving "who am I, what's my spi situation" energy 🫶
  • op — The register address and byte enables in message format. yes bestie, message format, she's fancy like that ✨
  • rxb — The RX buffer to return the result into. this is where the data lands, no cap 📥
  • rxl — The length of data expected. be honest about it or things get weird 😭

👑 DESCRIPTION 👑

so basically: this is the low level read call. like, the actual one underneath everything else. she issues the necessary spi message(s) to read data from the register specified in op. that's it, that's the whole vibe. main character energy but make it a spi transaction 💜

fr fr, "low level" means the layers above her are counting on her to do the thing correctly — she's the one talking to the hardware, periodt.
