STRUCT AT91_RESET(9)

💅 struct at91_reset(9) 💅

okay bestie, welcome to the Kernel API Manual — this page is literally all about struct at91_reset, the AT91 reset-specific data structure. it’s giving “reset controller main character energy” and we’re obsessed ✨

🌸 NAME 🌸

struct at91_reset is the AT91 reset specific data structure — the dedicated struct for AT91 reset stuff, periodt 💖

✨ SYNOPSIS ✨

struct at91_reset {
    void __iomem *rstc_base;
    void __iomem *ramc_base[2];
    void __iomem *dev_base;
    struct clk *sclk;
    const struct at91_reset_data *data;
    struct reset_controller_dev rcdev;
    spinlock_t lock;
    struct notifier_block nb;
    u32 args;
    u32 ramc_lpr;
};

🎀 Members 🎀

vibe check on the members — every single field is here, no skips, no cap:

• rstc_base — base address for system reset. that’s her home base 💅
• ramc_base — array with base addresses of RAM controllers. yes bestie, it’s an array, and the synopsis says [2] 🫶
• dev_base — base address for devices reset. slay.
• sclk — slow clock. lowkey essential.
• data — platform specific reset data. iykyk.
• rcdev — reset controller device. main character energy fr fr.
• lock — lock for devices reset register access. protect the register access, bestie 🔒
• nb — reset notifier block. not me being notified 🙈
• args — SoC specific system reset arguments. cute.
• ramc_lpr — SDRAM Controller Low Power Register. iconic name honestly 👑

🌈 SEE ALSO 🌈

• the SEE ALSO squad is: Kernel file ./drivers/power/reset/at91-reset.c, plus enum reset_type(9), struct at91_reset_data(9) — go read them, fr fr 💜
