From: Finley Xiao <finley.xiao@xxxxxxxxxxxxxx> Rk3399-efuse is organized as 32bits by 32 one-time programmable electrical fuses. The efuse of earlier SoCs are organized as 32bits by 8 one-time programmable electrical fuses with random access interface. Add different device tree compatible string for different SoCs to be able to differentiate between the two.
