STRUCT MSTP_CLOCK_GROUP(9)

💅 struct mstp_clock_group(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for struct mstp_clock_group — the MSTP gating clocks group situation, and she is lowkey iconic. no cap, this is the struct you need to understand if you're messing with these clocks. 🫶✨

---

🌸 NAME 🌸

struct mstp_clock_group — MSTP gating clocks group. literally the whole vibe. 🎀

---

✨ SYNOPSIS ✨

here's the struct in all its exact glory, bestie — copy-paste energy only:

       struct mstp_clock_group {
           struct clk_onecell_data data;
           void __iomem *smstpcr;
           void __iomem *mstpsr;
           spinlock_t lock;
           bool width_8bit;
           struct clk *clks[];
        };

---

🎀 Members 🎀

okay so let's do the member-by-member vibe check, because every field matters fr fr:

• data — this is the clock specifier translation for clocks in this group. it's giving "translation layer, but make it clock." 💖
• smstpcr — the module stop control register. yes bestie, that's the SMSTPCR energy. ⭐
• mstpsr — the module stop status register, and it's optional. so not every group is gonna have this one, and that's fine. 🦋
• lock — this spinlock protects writes to SMSTPCR. do not skip the lock, bestie, that's the whole point. 💅
• width_8bit — a bool that says the registers are 8-bit, not 32-bit. important distinction, no cap. 🔥
• clks — the clocks in this group. they live here. periodt. 👑
