1* AC timing parameters of LPDDR3 memories for a given speed-bin.

3The structures are based on LPDDR2 and extended where needed.
4
5Required properties:
6- compatible : Should be "jedec,lpddr3-timings"
7- min-freq : minimum DDR clock frequency for the speed-bin. Type is <u32>
8- reg : maximum DDR clock frequency for the speed-bin. Type is <u32>
9
10Optional properties:
11
12The following properties represent AC timing parameters from the memory
13data-sheet of the device for a given speed-bin. All these properties are
14of type <u32> and the default unit is ps (pico seconds).
