💅 ice_write_sma_ctrl(9) — Kernel API Manual 🫶

🌸 NAME 🌸

ice_write_sma_ctrl — bestie, the NAME line is literally just the function name and a lil' dash. No extra description. We move. ✨

✨ SYNOPSIS ✨

int ice_write_sma_ctrl (struct ice_hw *hw , u8 data );

🎀 ARGUMENTS 🎀

  • hw — pointer to the hw struct. That's the hardware bestie you're handing over. 💖
  • data — data to be written to the GPIO controller. It's the payload, periodt. 🫶

🦋 DESCRIPTION 🦋

Okay so this one writes the data to the SMA controller. That's the whole main quest. ✨

The SMA controller is connected to pins 3-7 of Port 1 of the PCA9575 expander, so only bits 3-7 in data are valid. The way this is giving "narrow bit window" — respect it. 💅

Bestie, only bits 3-7 in data are valid. That's not a suggestion, that's the map. 🗺️

🌈 SEE ALSO 🌈

Kernel file: ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c — yes, that's home base. 🏠
