The dts default is "okay", and should be fine for all the
internal devices even if not pinned out on the board. This
way the devices get properly idled during boot, and we
avoid repeating status = "enabled" over and over again in
the board specific dts files.
Then the board specific dts files might want to configure
devices with status = "disabled" if really needed. But this
should be only done for devices that Linux must not use,
such as crypto acclerators on secure devices if claimed by
the secure mode.
So if this fixes something, it's almost certainly a sign
of something else being broken?
Regards,
Tony
