The vdec IP block of RK322x is the same as RK3399 has and the driver can be used as-is. Add the respective node to the device tree. Note: core and cabac clock need to be set to a specific rate which is done by using "assigned-clocks" / "assigned-clock-rates" properties (axi clock rate is currently set in the driver).
