💖 struct samsung_retention_data(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for struct samsung_retention_data(9). This little struct is giving “pin-bank retention control data” energy, and we’re gonna read it together, no cap. 🎀

✨ NAME ✨

struct samsung_retention_data — represent a pin-bank retention control data.

Literally the struct that represents a pin-bank retention control data. That’s the whole name vibe, and we’re obsessed. 💅

🌸 SYNOPSIS 🌸

Here’s the exact shape of the struct, bestie — keep the line breaks and everything:

       struct samsung_retention_data {
           const u32       *regs;
           int nr_regs;
           u32 value;
           atomic_t *refcnt;
           struct samsung_retention_ctrl *(*init)(struct
       samsung_pinctrl_drv_data *, const struct samsung_retention_data *);
        };

🎀 Members 🎀

• regs — array of PMU registers to control pad retention. the register lineup for pad-retention control, periodt.
• nr_regs — number of registers in regs array. just the count of registers in that regs array.
• value — value to store to registers to turn off retention. the value that gets stored to the registers to turn off retention, slay.
• refcnt — atomic counter if retention control affects more than one bank. an atomic counter for when retention control affects more than one bank.
• init — platform specific callback to initialize retention control. platform specific callback that initializes retention control.
