Lines Matching +full:lpddr3 +full:- +full:timings

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
17 These values shall be obtained from the device data-sheet.

41 - The lpddr3 node may have one or more child nodes of type "lpddr3-timings".
42   "lpddr3-timings" provides AC timing parameters of the device for
43   a given speed-bin. Please see Documentation/devicetree/
44   bindings/ddr/lpddr3-timings.txt for more information on "lpddr3-timings"
