3 This binding uses the common clock binding[1]. 3 This binding uses the common clock binding[1]. It assumes a register mapped
4 clock which can be put to idle automatically b 4 clock which can be put to idle automatically by hardware based on the usage
5 and a configuration bit setting. Autoidle cloc 5 and a configuration bit setting. Autoidle clock is never an individual
6 clock, it is always a derivative of some basic 6 clock, it is always a derivative of some basic clock like a gate, divider,
7 or fixed-factor. 7 or fixed-factor.
