STRUCT CDNS_WDT(9)

💖 struct cdns_wdt(9) 💖

okay bestie, this is the Kernel API Manual page for struct cdns_wdt(9), and it's literally the watchdog device structure. no cap, we're gonna go through every member together 🫶

🌸 NAME 🌸

struct cdns_wdt — Watchdog device structure. that's the whole name, and it ate 💅

✨ SYNOPSIS ✨

here's the struct, exactly as it appears — don't let the alignment fool you, it's iconic:

       struct cdns_wdt {
           void __iomem            *regs;
           bool rst;
           struct clk              *clk;
           u32 prescaler;
           u32 ctrl_clksel;
           spinlock_t io_lock;
           struct watchdog_device  cdns_wdt_device;
        };

🦋 Members 🦋

• regs — the baseaddress of device fr fr 🎀
• rst — the reset flag 🚩
• clk — the struct clk * of a clock source ⏰
• prescaler — for saving prescaler value 💾
• ctrl_clksel — counter clock prescaler selection 🎛️
• io_lock — spinlock for IO register access 🔒
• cdns_wdt_device — watchdog device structure 🐶

💜 Description 💜

Structure containing parameters specific to cadence watchdog. so yeah, it's the struct that holds the params specific to the cadence watchdog — lowkey important, highkey slay 🎀
