💖 of_get_min_tck(9) — Kernel API Manual 💖

okay so bestie, welcome to the of_get_min_tck(9) page from the Kernel API Manual. This is the one about extracting min timing values for ddr, and we are keeping every technical crumb intact. no cap 🫶

✨ NAME ✨

of_get_min_tck — extract min timing values for ddr 💅

🌸 SYNOPSIS 🌸

const struct lpddr2_min_tck * of_get_min_tck (struct device_node *np ,
struct device *dev );

🎀 ARGUMENTS 🎀

• np — pointer to ddr device tree node. That’s the node, bestie.
• dev — device requesting for min timing values. It’s the one sliding into the function asking for the timing tea 🍓

🦋 DESCRIPTION 🦋

Okay so here’s the main-character move: of_get_min_tck populates the lpddr2_min_tck structure by extracting data from device tree node. It returns a pointer to the populated structure. If any error in populating the structure, it returns default min timings provided by JEDEC. That’s the whole vibe — populate from the node, hand back the pointer, and if populating goes sideways, the JEDEC defaults are the safety net 😭✨
