[ Upstream commit f7f9da89bc4f61e33f7b9f5c75c4efdc1f0455d8 ]
The clock controller registers are not 0x460 wide because the reset controller starts at CBUS 0x4404. This currently overlaps with the clock controller (which is at CBUS 0x4000).
There is no public documentation available on the actual size of the clock controller's register area (also called "HHI"). However, in Amlogic's GPL kernel sources the last "HHI" register is HHI_HDMI_PHY_CNTL2 at CBUS + 0x43a8. 0x400 was chosen because that size doesn't seem unlikely.
