Can we hook a device as device to two different parent devices?

[Rajesh Kumar]

Hi,

Is it really possible to declare a module with two parents? Like the
following declarations in the same driver.

devclass_t test_dev_devclass;
static DEFINE_CLASS_0(test_dev, test_dev_driver, test_dev_methods,
sizeof(struct test_dev_ctx));
DRIVER_MODULE(test_dev, *device1*, test_dev_driver, test_dev_devclass,
NULL, NULL);
DRIVER_MODULE(test_dev, *device2*, test_dev_driver, test_dev_devclass,
NULL, NULL);

I see similar references in other drivers attaching to both simpleus and
ofwbus. So, If it's possible, how to get the reference for both the
parents?  device_get_parent(test_dev) will give reference of one parent
only right, so how to get the reference of the desired parent?

Thanks,
Rajesh.
