1 * LPDDR3 SDRAM memories compliant to JEDEC JESD209-3C
4 - compatible : Should be "<vendor>,<type>", and generic value "jedec,lpddr3".
8 - density : <u32> representing density in Mb (Mega bits)
9 - io-width : <u32> representing bus width. Possible values are 8, 16, 32, 64
10 - #address-cells: Must be set to 1
11 - #size-cells: Must be set to 0
15 - manufacturer-id : <u32> Manufacturer ID value read from Mode Register 5
16 - revision-id : <u32 u32> Revision IDs read from Mode Registers 6 and 7
20 These values shall be obtained from the device data-sheet.
