1 * Peripheral Clock bindings for Marvell Armada 37xx SoCs
3 Marvell Armada 37xx SoCs provide peripheral clocks which are
4 used as clock source for the peripheral of the SoC.
6 There are two different blocks associated to north bridge and south
9 The peripheral clock consumer should specify the desired clock by
10 having the clock ID in its "clocks" phandle cell.
12 The following is a list of provided IDs for Armada 370 North bridge clocks:
13 ID Clock name Description
