cxd2820r_attach(9)

✨ NAME ✨

okay so bestie, this is the cxd2820r_attach(9) page from the Kernel API Manual 💖 and it's literally about attaching a cxd2820r demod. iconic little helper behavior, no cap.

🌸 SYNOPSIS 🌸

struct dvb_frontend * cxd2820r_attach (const struct cxd2820r_config
*config , struct i2c_adapter *i2c , int *gpio_chip_base );

🎀 ARGUMENTS 🎀

• config — pointer to struct cxd2820r_config with demod configuration, aka the lil setup info 💅
• i2c — the i2c adapter to use 🦋
• gpio_chip_base — if it's zero, GPIO setting gets disabled 🙈 Otherwise: if CONFIG_GPIOLIB is set, it dynamically allocates the gpio base; if CONFIG_GPIOLIB is not set, it uses its value to set up the GPIO pins ✨

💖 RETURN 💖

On success you get the FE pointer, and on failure you get NULL 😭 periodt.
