Hi,
We would like to know if there is a way to distinguish between RV1108 and RV1108G versions in run-time.
The reason we are asking is because arch/arm/boot/dts/rv1108.dtsi defines the following operational points: 408, 600, 816, 1008 MHz, but the RV1108G version does not support 1GHz and its maximum operating frequency is 800MHz (not 816 MHz).
In the i.MX SoCs we can read a fuse that indicates the "speed grading" of the chip and decide which operating points could be used for that particular version.
Is there such a mechanism in RV1108? Any suggestions to limiting the RV1108G operational point at 800MHz?
Thanks
