psec_id_xlate(9)

💅 psec_id_xlate — the psec_id_xlate(9) glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one lives in the kernel and it's lowkey a translator girlie — she takes your pse_spec and turns it into the actual PSE line number, based on how many pse-cells you've got, but only when there's no pse_pi node. no cap. 🎀

✨ NAME ✨

psec_id_xlate — translate pse_spec to the PSE line number according to the number of pse-cells in case of no pse_pi node 🦋

🌸 SYNOPSIS 🌸

int psec_id_xlate (struct pse_controller_dev *pcdev , const struct
of_phandle_args *pse_spec );

💖 ARGUMENTS 💖

• pcdev — a pointer to the PSE controller device. yes she's the main character, she holds the controller energy 👑
• pse_spec — PSE line specifier as found in the device tree. literally where the vibes (and the cells) come from 🌈

⭐ RETURN ⭐

Returns 0 if #pse-cells = <0>. Return PSE line number otherwise. that's it, that's the whole personality 💅
