 * 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
