I think it would be useful to break this patch down into more than one
patch. At least the core changes to evb_rk3399/evb-rk3399.c and the
board specific changes. Also given these changes arre likely of
interest to other boards should they go to somewhere more central
than evb_rk3399/evb-rk3399.c to enable less code duplication across
rk3399 or even rockchip devices as a whole?
