fwnode_get_u...rop_for_name(9)

✨ fwnode_get_u32_prop_for_name (9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a kernel function, section 9, and it's literally called fwnode_get_u32_prop_for_name (the header abbreviates it to fwnode_get_u...rop_for_name(9) because terminal widths are haters, but you and i know the truth 🫶).

🌸 NAME 🌸

fwnode_get_u32_prop_for_name — find a u32 property by name, or fall back to a default value 💖

---

🎀 SYNOPSIS 🎀

int fwnode_get_u32_prop_for_name (struct fwnode_handle *fwnode , const
char *name , const char *props_title , const char *names_title ,
unsigned int default_val , unsigned int *val );

bestie that signature is long, drink some water before reading it 🥤

---

🦋 ARGUMENTS 🦋

• fwnode — pointer to a firmware node. or NULL if you'd rather just vibe with default_val 🙈
• name — the property name, used as the lookup key inside names_title. must not be NULL — like, fr fr, do not do that 💀
• props_title — name of the u32 array property that's holding the actual values 👑
• names_title — name of the string array property holding the lookup keys 🔑
• default_val — the default value, used when fwnode is NULL or when props_title is empty 🎁
• val — pointer where the returned value gets stored ✨

---

🌈 DESCRIPTION 🌈

so this function goes and grabs a u32 value out of props_title, based on a name lookup in names_title. the value that lands in val gets decided like this:

• if fwnode is NULL or props_title is empty → it uses default_val
• if props_title has exactly one element and names_title is empty → that one element is the one, that's the chosen one, main character energy 👑
• otherwise → val is set to the element at the same index where name is found in names_title
• if name isn't found at all → the function goes looking for a "default" entry in names_title and uses the corresponding value from props_title

⚠️ important bestie: when both props_title and names_title are present, they gotta have the same number of elements — the only exception is when props_title has exactly one element. don't make them mismatch, it's giving chaos 😭

⭐ RETURN ⭐

zero on success 🎉 — negative error on failure 😔
