🎀 NAME 🎀

mux_config_port — Perform port autoconfiguration. that’s literally the whole assignment, bestie. 💅

✨ SYNOPSIS ✨

void mux_config_port (struct uart_port *port , int type );

🌸 ARGUMENTS 🌸

• port — Ptr to the uart_port. yep, it’s the port pointer. 🫶
• type — Bitmask of required configurations. lowkey the settings menu. ✨

💅 DESCRIPTION 💅

okay so this function performs any autoconfiguration steps for the port. it gets called if the UPF_BOOT_AUTOCONF flag is specified for the port. 🛠️✨
