You can also just spawn a random platform_device from the HWMON driver
and let that probe a driver down in drivers/gpio/*.
static struct platform_device my_gpio_device = {
.name = "my-gpio",
.id = -1,
};
my_gpio_device.dev.platform_data = ... ;
my_gpio_device.dev.parent = dev;
return platform_device_register(&my_gpio_device);
You can then pass any accessors as platform data. This in a way is what
the MFD or aux buses do just more organized.
