okay bestie, welcome to viortc_ptp_register(9) from the Kernel API Manual ✨ this one is literally about prepare and register PTP clock, and no cap it’s giving “small but important kernel helper” energy 💅

🌸 NAME 🌸

viortc_ptp_register — prepare and register PTP clock 🎀

🦋 SYNOPSIS 🦋

struct viortc_ptp_clock * viortc_ptp_register (struct viortc_dev *viortc
, struct device *parent_dev , u16 vio_clk_id , const char
*ptp_clock_name );

💖 ARGUMENTS 💖

• viortc — the virtio_rtc device data, aka the main character data blob 🫶
• parent_dev — the parent device for the PTP clock.
• vio_clk_id — id of the virtio_rtc clock which backs the PTP clock.
• ptp_clock_name — the PTP clock name.

✨ CONTEXT ✨

Process context. bestie, that’s the whole vibe check here 💅
