STRUCT RZV2H_CPG_INFO(9)

🌸 struct rzv2h_cpg_info(9) 🌸

okay bestie, welcome to the Kernel API Manual — today's main character is struct rzv2h_cpg_info, and honestly? it's giving SoC-specific CPG Description ✨ it's the little data bundle that tells the clock/power gang everything it needs to know about a specific SoC. no cap, super important 💅

✨ NAME ✨

struct rzv2h_cpg_info — SoC-specific CPG Description 🎀

---

🦋 SYNOPSIS 🦋

struct rzv2h_cpg_info {
    const struct cpg_core_clk *core_clks;
    unsigned int num_core_clks;
    unsigned int last_dt_core_clk;
    unsigned int num_total_core_clks;
    const struct rzv2h_mod_clk *mod_clks;
    unsigned int num_mod_clks;
    unsigned int num_hw_mod_clks;
    const struct rzv2h_reset *resets;
    unsigned int num_resets;
    unsigned int num_mstop_bits;
 };

like, that's the whole vibe of it 🫶 ten fields, zero drama (mostly).

🎀 Members 🎀

• core_clks — Array of Core Clock definitions 🔥 the actual core-clock lineup.
• num_core_clks — Number of entries in core_clks[] ⭐ so you know how far to walk the array, iykyk.
• last_dt_core_clk — ID of the last Core Clock exported to DT 💖 the boundary marker between "exists for the kernel" and "exists for devicetree".
• num_total_core_clks — Total number of Core Clocks (exported + internal) 👑 both flavours counted together, no clock left behind.
• mod_clks — Array of Module Clock definitions 🌈 the module-clock roster.
• num_mod_clks — Number of entries in mod_clks[] 💜 your trusty array-length buddy.
• num_hw_mod_clks — Number of Module Clocks supported by the hardware 💀 hardware says what it says; this is the honest count.
• resets — Array of Module Reset definitions 🧚 all the reset definitions, neatly arrayed.
• num_resets — Number of entries in resets[] 🌸 length check, slay.
• num_mstop_bits — Maximum number of MSTOP bits supported, equivalent to the number of CPG_BUS_m_MSTOP registers multiplied by 16 🍓 (yes, literally that math — multiply by sixteen, periodt).

go read them, they ate 💅

ngl, and this is the important bit — the SEE ALSO list has no comma between the header file and the structs, so like... it's a list of things not a sentence. don't come for me, I'm just the messenger 🫶

and that's the whole page, bestie!! 🌈⭐ mwah 💋 this gem lives over in ./drivers/clk/renesas, and it's stamped October 2026 — so yes, this documentation is literally from the future 💀✨ go build something gorgeous with it 💖
