STRUCT CLK_HW_DATA(9)

✨ struct clk_hw_data — clock hardware data ✨

okay so you're reading the Kernel API Manual (section 9, kernel internals, iykyk) and you landed on struct clk_hw_data, which is literally just the lil bundle of clock hardware data 💅 bestie it's a struct, it's not that deep, but let's go through it together anyway because every field ate.

🌸 SYNOPSIS 🌸

here's the shape of it, exactly as it lives in the kernel:

struct clk_hw_data {
    struct clk_hw hw;
    u32 conf;
    u32 sconf;
    struct rzg2l_cpg_priv *priv;
 };

no cap, that's the whole vibe. four fields, zero drama 🎀

👑 Members 👑

• hw — the clock hw. fr fr, that's it, that's the member 🫶
• conf — clock configuration, and it's a whole trio: register offset, shift, and width. the way it packs all that in one u32… iconic 🔥
• sconf — clock status configuration, same trio energy: register offset, shift, width ⭐
• priv — the CPG private data structure. it's giving "backstage pass to the private data" 💜

🦋 SEE ALSO 🦋

• Kernel file ./drivers/clk/renesas/rzg2l-cpg.c — go read it, it's literally where this struct hangs out 🌈
• struct sd_mux_hw_data(9)
• struct div_hw_data(9)
• struct rzg2l_cpg_priv(9)
• struct mstop(9)
• struct mod_clock(9)

all siblings, all besties, all worth a peek 👀

ngl, if you're poking at the RZ/G2L clock driver, you're gonna see this struct a lot. bookworm behavior: read the SEE ALSO list first 💀
