STRUCT CDNSP_PORT_REGS(9)

🎀 struct cdnsp_port_regs(9) 🎀

okay so bestie, welcome to the kernel API manual — yes that kernel API manual, the one with the port registers. this page is literally all about struct cdnsp_port_regs, aka Port Registers, and ngl it's a short one but it's iconic. let's get into it 💅

---

✨ NAME ✨

struct cdnsp_port_regs — Port Registers. that's it, that's the name, she's self-explanatory and she knows it 🫶

---

🌸 SYNOPSIS 🌸

here's the whole struct, no crumbs, exactly as she is:

struct cdnsp_port_regs {
    __le32 portsc;
    __le32 portpmsc;
    __le32 portli;
    __le32 reserved;
 };

four __le32 fields, one of them just vibing in the back as reserved 😌

---

💖 Members 💖

• portsc — PORTSC — the Port Status and Control Register. status AND control, she does both, main character energy fr ✨
• portpmsc — PORTPMSC — the Port Power Managements Status and Control Register. yes the name really says "Managements", we don't fix it, we respect it 💀 power management queen 👑
• portli — PORTLI — the Port Link Info register. the link info, the lore, the details 🔥

okay and real talk: reserved is in the struct up there in the synopsis but the page doesn't give it a Members entry — so we're not gonna make one up. she's reserved, that's her whole personality 🙈
