According to P45 of <<Rockchip RK3308 Datasheet V1.0-20180313>>,
the max voltage for Logic is 1.1V, so for many boards which
Core_VDD and Logic_VDD share the same power supply, the ARM
core voltage will be limited to 1.1V, that can only guarantee
the cpu to run at the max freq of 1008MHZ.
As for board which Core_VDD and Logic_VDD use independent
power supply, the cpu can run a higher freq up to 1296MHZ
with higher Core_VDD power supply, you can eanble it in
your board dts.
