STRUCT OMAP1_CLK(9)

💅 struct omap1_clk — the OMAP1 struct clk moment

okay so this is straight out of the Kernel API Manual, and it's literally the whole personality of the OMAP1 clock struct, laid out for you. no cap, it's giving "let me introduce you to every field bestie" energy 🎀

---

✨ NAME ✨

struct omap1_clk — OMAP1 struct clk. that's it, that's the name, slay 💖

---

🌸 SYNOPSIS 🌸

here's the whole struct, bestie, exactly as it lives:

struct omap1_clk {
    struct clk_hw           hw;
    const struct clkops     *ops;
    unsigned long           rate;
    void __iomem            *enable_reg;
    unsigned long           (*recalc)(struct omap1_clk *clk, unsigned long rate);
    int (*set_rate)(struct omap1_clk *clk, unsigned long rate, unsigned long p_rate);
    long (*round_rate)(struct omap1_clk *clk, unsigned long rate, unsigned long *p_rate);
    int (*init)(struct omap1_clk *clk);
    u8 enable_bit;
    u8 fixed_div;
    u8 flags;
    u8 rate_offset;
 };

look at all those little fields, they're like a whole friend group honestly 🫶

👑 Members 👑

like, member by member, so you know exactly who's who:

• hw — the struct clk_hw for common clock framework integration. this is the one that lets your clock hang out with the cool common-clock-framework crowd ✨
• ops — the struct clkops * for this clock. its whole designated-ops situation 💅
• rate — the current clock rate. right now, in real time, that's the number 🕐
• enable_reg — the register you write to in order to enable the clock (peep enable_bit, they're a package deal 👀)
• recalc — fn ptr that returns the clock's current rate. it's the "what's your rate rn" friend 🔥
• set_rate — fn ptr that can change the clock's current rate. the makeover friend 💫
• round_rate — fn ptr that can round the clock's current rate. the "close enough bestie" friend 🎀
• init — fn ptr to do clock-specific initialization. the setup era, the glow-up prequel 🌱
• enable_bit — the bitshift to write to enable/disable the clock (see enable_reg). yes, these two are inseparable, iykyk 🔗
• fixed_div — when > 0, this clock's rate is its parent's rate / fixed_div. literally parent's rate divided by fixed_div, math ate 💅
• flags — see "struct clk.flags possibilities" above. go look up there bestie, the flag lore lives up there ⬆️
• rate_offset — the bitshift for the rate selection bitfield (OMAP1 only, so if you're not on OMAP1, this one's not for you 🙈)
