ice_dpll_init_fwnode_pins(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, buckle up 🫶 this is ice_dpll_init_fwnode_pins(9) from the Kernel API Manual, and it's giving “let's initialize some pins from the device tree” energy. no cap. 💅

✨ NAME ✨

ice_dpll_init_fwnode_pins — initialize pins from device tree 🌳✨

📜 SYNOPSIS 📜

the signature is doing its little C thing, exactly like this:

int ice_dpll_init_fwnode_pins (struct ice_pf *pf , struct ice_dpll_pin
       *pins , int start_idx );

🧡 ARGUMENTS 🧡

  • pf — board private structure 🫶
  • pins — pointer to pins array ✨
  • start_idx — starting index for pins 🎀

🎀 DESCRIPTION 🎀

Okay so what this function is actually doing: it initializes input pins for E825 RCLK support. The parent pins (rclk0, rclk1) are expected to be defined by the system firmware (ACPI). This function allocates them in the dpll subsystem and stores their indices for later registration with the rclk pin. that's the whole lore, fr fr.

💖 RETURN 💖

  • 0 — success. we love a zero 😌✨
  • negative — initialization failure reason. if it comes back negative, init failed and the negative value is the reason.
