sdw_enable_d..._slave_ports(9)

🌸 NAME 🌸

sdw_enable_disable_slave_ports — Enable/disable slave data port, bestie. This is the sdw_enable_d..._slave_ports(9) page from the Kernel API Manual, and it's giving very specific SoundWire energy. 💖

---

✨ SYNOPSIS ✨

int sdw_enable_disable_slave_ports (struct sdw_bus *bus , struct
       sdw_slave_runtime *s_rt , struct sdw_port_runtime *p_rt , bool en );

---

🎀 ARGUMENTS 🎀

• bus — your bus instance, the main character holding the whole setup together.
• s_rt — the slave runtime. Yep, that's the vibe.
• p_rt — the port runtime, lowkey the port-specific bestie.
• en — the enable/disable operation toggle, literally the yes/no of it all.

---

💅 DESCRIPTION 💅

Okay so bestie, this function is on a very specific mission: it only sets the enable/disable bits in the relevant bank. That's it. That's the assignment. ✨

The actual enable/disable is done with a bank switch, so no cap — the bank switch is the one doing the real flipping. This function is just setting the bits and handing off the plot. 💅
