STRUCT ATCWDT_DRV(9)

💖 struct atcwdt_drv(9) 💖

okay bestie, this is straight outta the Kernel API Manual and it's giving kernel-private-data realness ✨

🌸 NAME 🌸

struct atcwdt_drv — ATCWDT200 watchdog driver private data. yep, it's the private-data bundle for this watchdog driver, no cap 💅

🦋 SYNOPSIS 🦋

struct atcwdt_drv {
    struct watchdog_device  wdt_dev;
    struct regmap           *regmap;
    struct clk              *clk;
    spinlock_t lock;
    unsigned int            clk_freq;
    unsigned char           clk_src;
    unsigned char           int_timer_type;
};

🎀 Members 🎀

• wdt_dev — Watchdog device used by the watchdog framework. literally the watchdog-framework-facing device, slay 🫶
• regmap — Register map for accessing hardware registers. your little map to the hardware registers ✨
• clk — Hardware clock used by the watchdog timer. the hardware clock the watchdog timer runs on 💫
• lock — Spinlock protecting register accesses and driver state. keeps register accesses and driver state safe, periodt 🔒
• clk_freq — Input clock frequency of the ATCWDT200. the input clock frequency, noted 🎀
• clk_src — Selected clock source for the watchdog timer. which clock source got picked for the watchdog timer 👑
• int_timer_type — Detected interrupt timer type (16-bit, 32-bit, or unknown). the detected interrupt timer type — 16-bit, 32-bit, or unknown, iykyk 💀
