💖 stmp3xxx_wdt_set_timeout(9) — Kernel API Manual 💖

okay bestie, welcome to the little corner of the kernel docs where we configure the watchdog inside the STMP3xxx RTC ✨

🎀 NAME 🎀

stmp3xxx_wdt_set_timeout — configure the watchdog inside the STMP3xxx RTC 💅

🌸 SYNOPSIS 🌸

void stmp3xxx_wdt_set_timeout (struct device *dev , u32 timeout );

🦋 ARGUMENTS 🦋

• dev — the parent device of the watchdog (= the RTC) 🫶
• timeout — the desired value for the timeout register of the watchdog. 0 disables the watchdog 💀

✨ DESCRIPTION ✨

So the watchdog needs one register and two bits which are in the RTC domain 👑. To handle the resource conflict, the RTC driver will create another platform_device for the watchdog driver as a child of the RTC device 🌈.

The watchdog driver is passed the below accessor function via platform_data to configure the watchdog 🧚.

Locking is not needed because accessing SET/CLR registers is atomic 🔥. no cap, that's the whole reason it's chill like that 💅
