It worked fine that single sysctrl/mediactrl device node in DT can be used to initialize clock driver and populate platform device for reset controller. But it stops working after commit 989eafd0b609 ("clk: core: Avoid double initialization of clocks") gets merged. The commit sets flag OF_POPULATED during clock initialization to skip the platform device populating for the same device node. On hi6220, it effectively makes hi6220-sysctrl reset driver not probe any more. The patch changes hi6220 sysctrl and mediactrl clock init macro from CLK_OF_DECLARE to CLK_OF_DECLARE_DRIVER, so that the reset driver using the same hardware block can continue working.
