Some module is divided to sub-modules which are designed in different
h/w blocks for different usage, and if we want to use the same
compatible to present these h/w blocks, we need to move the clock data
provided by these h/w blocks to dts, but we usually use different
compatible to get the h/w blocks data in
Mediatek's clock driver, so do you suggest to register clock provided
by different h/w blocks using same compatible?
