🎀 of_lpddr2_get_info(9) 🎀

okay so welcome to the Kernel API Manual, bestie — this is the page for of_lpddr2_get_info(9), and it’s giving very specific kernel-helper energy. it extracts information about the lpddr2 chip, and we’re gonna walk through it like a group chat. no cap. 💖✨

🌸 NAME 🌸

of_lpddr2_get_info — extracts information about the lpddr2 chip. 🧚🦋

✨ SYNOPSIS ✨

here’s the signature, copied character-for-character so nobody comes for me:

const struct lpddr2_info * of_lpddr2_get_info (struct device_node *np ,
struct device *dev );

🫶 ARGUMENTS 🫶

• np — pointer to the device tree node containing lpddr2 info. that’s the source of the tea. 🍓
• dev — the device requesting info. hi bestie, what’s the vibe? 💅

💜 DESCRIPTION 💜

okay so this function populates the lpddr2_info structure by extracting data from the device tree node. it returns a pointer to the populated structure — iconic. 👑

if an error happened while populating, it returns NULL 😭 — literally no pointer, bestie. and if a property is missing in a device-tree, then the corresponding value is set to -ENOENT — that’s the exact value, periodt. no cap. 💀
