atmel_hsmc_get_reg_layout(9)

💖 atmel_hsmc_get_reg_layout — like, the manual page, bestie 💖

okay so this is a page from the Kernel API Manual and honestly? it's a little one but she's important, so pay attention 🎀

---

✨ NAME ✨

atmel_hsmc_get_reg_layout — grab yourself the layout of HSMC registers. that's it. that's the whole job. 💅

---

🌸 SYNOPSIS 🌸

const struct atmel_hsmc_reg_layout * atmel_hsmc_get_reg_layout (struct
device_node *np );

like, you hand her a device node and she hands you back a const struct atmel_hsmc_reg_layout * — no cap 🫶

---

🦋 ARGUMENTS 🦋

• np — the HSMC regmap. that's the one thing she wants from you, bestie 🍓

---

💜 DESCRIPTION 💜

Retrieve the layout of HSMC registers. simple, iconic, does what it says on the tin ✨

now here's the ✨vibe check✨ on what actually comes back to you — and this part matters, so don't skim it, i'm serious 😭:

• Returns NULL in case of SMC
• Returns a struct atmel_hsmc_reg_layout pointer in the HSMC case
• Otherwise? it's giving ERR_PTR(-EINVAL) 💀

so yeah. three possible outcomes, and you will be checking which one you got. that's not a suggestion, that's main character energy for your error handling 🔥
