STRUCT RZ_SYSC_INIT_DATA(9)

💅 struct rz_sysc_init_data(9) 💅

okay so bestie, welcome to the Kernel API Manual (section 9, the ~cool~ section), and today's main character is struct rz_sysc_init_data — literally the RZ SYSC initialization data. she's a struct, she holds the vibes, she gets the regmap configured. no cap. 🎀

---

✨ NAME ✨

struct rz_sysc_init_data — RZ SYSC initialization data. that's it, that's the whole vibe check. 🦋

---

🌸 SYNOPSIS 🌸

struct rz_sysc_init_data {
    const struct rz_sysc_soc_id_init_data *soc_id_init_data;
    bool (*writeable_reg)(struct device *dev, unsigned int reg);
    bool (*readable_reg)(struct device *dev, unsigned int reg);
    u32 max_register;
 };

look at her. four fields. clean. iconic. copy-paste her exactly, i'm begging you. 🫶

• soc_id_init_data — RZ SYSC SoC ID initialization data. yes it's a pointer, yes it's const struct rz_sysc_soc_id_init_data *, yes i typed it twice on purpose. 🔥
• writeable_reg — the Regmap writeable register check function. it's a function pointer: bool (*writeable_reg)(struct device *dev, unsigned int reg). she checks whether a register is writeable, and that's the whole job. periodt. ✨
• readable_reg — the Regmap readable register check function. also a function pointer: bool (*readable_reg)(struct device *dev, unsigned int reg). same energy, but reading. the way that symmetry ate. 💅
• max_register — maximum SYSC register offset to be used by the regmap config. it's a u32. she's the ceiling, she sets the limit, she's the boundary queen. 👑

• Kernel file ./drivers/soc/renesas/rz-sysc.h — go read it, iykyk. 📖

reminder bestie: these field names are spelled exactly like that, including writeable_reg and readable_reg. don't "fix" them to "writable" or the kernel will simply know and it will not slay. 💀

and that's the whole page, mwah 💖

sign-off time: this little gem came from ./drivers/soc/renesas, dated October 2026, living inside the Kernel API Manual — so when you cite her, cite her right. 🎀✨🦋💜
