RV1108G run-time detection

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
