So 6 unsigned long 32 bit is succeeded by 6 unsigned long long, 64 bit?
Someone is having fun naming these platforms I see.

Pretty uncontroversial change but still nice to give the DT people a chance
to ACK it.

1. Do not use a cast on void * pointers.
2. Use this function:
extern const void *of_device_get_match_data(const struct device *dev);
