STRUCT ROCKCHIP_DRV(9)

👑 NAME

struct rockchip_drv — bestie, this is the pinctrl struct that tells the Rockchip driver how strong a pin should drive and where in the register map it should go looking for that setting 💅

✨ SYNOPSIS

struct rockchip_drv {
    enum rockchip_pin_drv_type      drv_type;
    int offset;
 };

literally the whole thing, no cap — two members and a dream 🎀

🌸 Members 🌸

• drv_type — this is the drive strength variant, and it's typed as enum rockchip_pin_drv_type (the per-pin flavour, iykyk). So it's saying which drive strength config we're working with 🔥
• offset — okay so this one's the main character 🙈 if you initialize it to -1 it gets autocalculated for you, no manual labour required. But if you pass in an initial offset value instead, the relevant source offset can be reset to a new value, and then it autocalculates the following drive strength registers from there. One tiny caveat tho: if the chip has its own cal_drv func that calculates the register offsets itself, this whole variant could just be ignored entirely 💀

fr fr, that -1 detail matters — set it and let the kernel do the math 🧚
