clk_register_divider(9)

💖 NAME 💖

okay bestie, welcome to the clk_register_divider(9) page in the Kernel API Manual — we're talking about clk_register_divider, which literally registers a divider clock with the clock framework. slay. ✨

🛠️ SYNOPSIS 🛠️

clk_register_divider (dev , name , parent_name , flags , reg , shift ,
       width , clk_divider_flags , lock );

🧚 ARGUMENTS 🧚

• dev — the device registering this clock, aka the one making it official.
• name — name of this clock. give her a good one 💅
• parent_name — name of clock's parent. family tree but make it hardware.
• flags — framework-specific flags.
• reg — register address to adjust divider. this is where the magic happens.
• shift — number of bits to shift the bitfield.
• width — width of the bitfield.
• clk_divider_flags — divider-specific flags for this clock. not the same vibe as the framework flags, iykyk.
• lock — shared register lock for this clock. sharing is caring, but also safety.
