Recent Rockchip SoCs have a new hardware block called Native Interface Unit (NIU), which gates clocks to devices behind them. These clock gates will only have a running output clock when all of the following conditions are met: 1. the parent clock is enabled 2. the enable bit is set correctly 3. the linked clock is enabled To handle them this code registers them as a normal gate type clock, which takes care of condition 1 + 2. The linked clock is handled by using runtime PM clocks. Handling it via runtime PM requires setting up a struct device for each of these clocks with a driver attached to use the correct runtime PM operations. Thus the complete handling of these clocks has been moved into its own driver.
