* 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
Marvell Armada 370/375/380/385/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

lookup in datasheet.
