Given that the devicetree for RV1103 in Rockchip downstream kernel tree includes RV1106's devicetree[1] and only adds some overrides, I'd like to say RV1103 is basically only in a different package. They're likely the same silicon, probably with different qualities. > I only ask since the RV1106 SoC has a similar prefix to the RV1103.
