STRUCT DDIV(9)

okay bestie, this is struct ddiv(9) from the Kernel API Manual, and it’s giving “dynamic switching divider but make it a struct” ✨💅

💖 NAME 💖

struct ddiv — Structure for dynamic switching divider. That’s the whole name, no cap. 🫶

✨ SYNOPSIS ✨

       struct ddiv {
           unsigned int offset:11;
           unsigned int shift:4;
           unsigned int width:4;
           unsigned int monbit:5;
           unsigned int no_rmw:1;
        };

🦋 Members 🦋

• offset — register offset. the where, basically 📍
• shift — position of the divider bit. bit squad, line up ✨
• width — width of the divider. how wide the divider situation is 🎀
• monbit — monitor bit in CPG_CLKSTATUS0 register. monitor bit in CPG_CLKSTATUS0 register, literally 👀
• no_rmw — flag to indicate if the register is read-modify-write (1: no RMW, 0: RMW). read the flag, respect the flag 💅
