💖 NAME 💖

sdw_bus_master_add — add a bus Master instance

🌸 SYNOPSIS 🌸

int sdw_bus_master_add (struct sdw_bus *bus , struct device *parent ,

🎀 ARGUMENTS 🎀

• bus — the bus instance itself, the whole vibe, the star of the show 🦋
• parent — the parent device, i.e. who's claiming this little guy 💅
• fwnode — the firmware node handle, the ✨firmware lore✨

🌈 DESCRIPTION 🌈

So what does it actually do? Three things, and honestly? ate:

1. Initializes the bus instance
2. reads properties
3. creates child devices
