* Gated Clock bindings for Marvell EBU SoCs



Marvell Armada 370/375/XP, Dove and Kirkwood allow some peripheral clocks to be

gated to save some power. The clock consumer should specify the desired clock

by having the clock ID in its "clocks" phandle cell. The clock ID is directly

mapped to the corresponding clock gating control bit in HW to ease manual clock
