cdns_ufs_set_hclkdiv(9)

💖 NAME 💖

cdns_ufs_set_hclkdiv — bestie, this one literally sets the HCLKDIV register value based on the core_clk. That's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

int cdns_ufs_set_hclkdiv (struct ufs_hba *hba );

---

🎀 ARGUMENTS 🎀

• hba — the host controller instance, aka the main character of this whole function 🫶

---

⭐ RETURN ⭐

So the tea is: it gives you back zero for success and non-zero for failure. That's it. Zero = slay, anything else = 😭

💅 SEE ALSO 💅

Ok so if you wanna keep the lore going, go read the kernel file ./drivers/ufs/host/cdns-pltfrm.c — it's all right there, no cap 👑

And then these iconic little siblings, all section (9), all obsessed with each other:

• cdns_ufs_get_l4_attr(9)
• cdns_ufs_set_l4_attr(9)
• cdns_ufs_hce_enable_notify(9)
• cdns_ufs_hibern8_notify(9)
• cdns_ufs_link_startup_notify(9)
• cdns_ufs_init(9)
• cdns_ufs_m31_16nm_phy_initialization(9)
• cdns_ufs_pltfrm_probe(9)
• cdns_ufs_pltfrm_remove(9)

Go read them. Not me being a good influence for once 🙈
