The HHI register region provides more than just clocks. Several drivers may need to access this region, such as the clock controllers and the display driver. Meson-gx clock controllers has been developed and merged before we knew the hhi could be needed elsewhere, which is why it requests the region directly. Meson-axg was built following the model of meson-gx. To fix this situation, the clock controller should be a child of the hhi system controllers. The hhi system controller node already exists on meson-gx. It needs to be added on the axg. This changeset depends on [0]. This dependency has been merged in clk-next.
