sdw_get_slave_dpn_prop(9)

💅 sdw_get_slave_dpn_prop — Get Slave port capabilities

okay bestie, welcome to the Kernel API Manual ✨ this one's a tiny little function but it's literally the main character of port-capability lookups, so let's get into it 🫶

---

🌸 NAME

sdw_get_slave_dpn_prop — Get Slave port capabilities 💖

---

✨ SYNOPSIS

struct sdw_dpn_prop * sdw_get_slave_dpn_prop (struct sdw_slave *slave ,
enum sdw_data_direction direction , unsigned int port_num );

that's the whole vibe check right there — you hand it a slave, a direction, and a port number, and it hands you back a struct sdw_dpn_prop * 🎀

---

🦋 ARGUMENTS

• slave — the Slave handle 👑 like, this is your actual soundwire slave, no cap
• direction — the data direction 🌈 (enum sdw_data_direction, iykyk)
• port_num — the port number 🔢 literally just which port you're asking about
