Tero Kristob1a07b42013-06-18 16:27:57 +03001Binding for Texas Instruments autoidle clock.
2
3Binding status: Unstable - ABI compatibility may be broken in the future
4
5This binding uses the common clock binding[1]. It assumes a register mapped
6clock which can be put to idle automatically by hardware based on the usage
7and a configuration bit setting. Autoidle clock is never an individual
8clock, it is always a derivative of some basic clock like a gate, divider,
9or fixed-factor.

13Required properties:
14- reg : offset for the register controlling the autoidle
15- ti,autoidle-shift : bit shift of the autoidle enable bit
16- ti,invert-autoidle-bit : autoidle is enabled by setting the bit to 0
