As was discussed earlier too, status field of DT node is not supposed
to be used for
keeping an IP enabled or disabled. That should be done via the kernel
config. The DT status
is mostly to indicate the hardware status of the IP on the SoC/board.
If the node fully defines the hardware,
then it should be kept enabled by default unless such enabling causes
some issues with other IPs due to
pin sharing conflicts, etc. In the above case the node completely
defines the hardware and hence there is no
reason to keep it disabled.
