Revisiting RK3399 LPDDR speeds
#2
I *think* the required bits for DDR frequency scaling are in the kernel, but nobody has shipped DTS files with any of the required sections.

It also just makes a call down into the appropriate ATF layer to do the actual scaling, so requires support down there as well. I would hope the BSP UBoot/ATF have support, but I've not verified it yet. Will keep poking...
