+* Device Tree Bindings for Freescale i.MX Clock
+
+== Clock Gate ==
+
+Required properties:
+- imx,clock-gate: It's a two 32-bit integers array. The first
+ integer specifies the offset of the gate register, and the second
+ one specifies the bit mask of the gate for this clock.
+
+== Clock Divider ==
+
+Required properties:
+- imx,clock-divider: It's a five 32-bit integers array. The first
+ integer specifies the offset of the divider register. The second
+ and the third one specify the shift and width of the pre-divider
+ bits for the clock, which is not necessarily present and the values
+ can just be 0. The last two specify the shift and width of the
+ post-divider bits.
+
+Optional properties:
+- imx,busy-divider: Some imx clocks needs to wait for a busy status
+ cleared when the clock rate gets changed. This property is a two
+ 32-bit integers array. The first integer specifies the offset of
+ the busy register, and the second one specifies the busy bit mask.
+
+== Clock Multiplexer ==
+
+Required properties:
+- imx,clock-multiplexer: It's a three 32-bit integers array. The
+ first integer specifies the offset of the multiplexer register.
+ The second and the third one specify the shift and width of the
+ multiplexer bits for this clock.
+
+Optional properties:
+- imx,busy-multiplexer: Some imx clocks needs to wait for a busy
+ status cleared when the parent gets changed. This property is a two
+ 32-bit integers array. The first integer specifies the offset of
+ the busy register, and the second one specifies the busy bit mask.
+
+A typical imx clock could have gate, divider, multiplexer, but it's
+also very true that a imx clock just has the subset of these three
+properties.
+
+When #clock-cells > 1, this single clock node actually describes
+multiple clocks. Thus all the properties under the node should
+contains the description for all of the clocks, except properties
+clock-input and clock-input-name which are used to describe the
+parents of the clock. That means only the clocks sharing the exactly
+same parents could possible described by single node.
