STRUCT RMI_TRANSPORT_DEV(9)

💖 struct rmi_transport_dev(9) 💖 — Kernel API Manual

okay so bestie, this is the struct rmi_transport_dev(9) page from the Kernel API Manual, and it’s literally the blueprint for an RMI transport device. Vibe check: passed 💅✨

🌸 NAME 🌸

struct rmi_transport_dev — represent an RMI transport device.

✨ SYNOPSIS ✨

       struct rmi_transport_dev {
           struct device *dev;
           struct rmi_device *rmi_dev;
           const char *proto_name;
           const struct rmi_transport_ops *ops;
           struct rmi_device_platform_data pdata;
           struct input_dev *input;
        };

🎀 Members 🎀

Member vibe check — these are the four the manpage spells out (and yes, pdata and input are still in the struct up there, bestie):

• dev — Pointer to the communication device, e.g. i2c or spi 💅
• rmi_dev — Pointer to the RMI device
• proto_name — name of the transport protocol (SPI, i2c, etc)
• ops — pointer to transport operations implementation

💅 Description 💅

The RMI transport device implements the glue between different communication buses such as I2C and SPI. It’s giving matchmaker energy for buses, and honestly that’s iconic 🦋
