1* EMIF family of TI SDRAM controllers 2 3EMIF - External Memory Interface - is an SDRAM controller used in 4TI SoCs. EMIF supports, based on the IP revision, one or more of 5DDR2/DDR3/LPDDR2 protocols. This binding describes a given instance 6of the EMIF IP and memory parts attached to it. 7 8Required properties: 9- compatible : Should be of the form "ti,emif-<ip-rev>" where <ip-rev> 10 is the IP revision of the specific EMIF instance. 11 12- phy-type : <u32> indicating the DDR phy type. Following are the 13 allowed values 14 <1> : Attila PHY 15 <2> : Intelli PHY 16 17- device-handle : phandle to a "lpddr2" node representing the memory part 18 19- ti,hwmods : For TI hwmods processing and omap device creation 20 the value shall be "emif<n>" where <n> is the number of the EMIF 21 instance with base 1. 22 23Optional properties: 24- cs1-used : Have this property if CS1 of this EMIF 25 instance has a memory part attached to it. If there is a memory 26 part attached to CS1, it should be the same type as the one on CS0, 27 so there is no need to give the details of this memory part. 28 29- cal-resistor-per-cs : Have this property if the board has one 30 calibration resistor per chip-select. 31 32- hw-caps-read-idle-ctrl: Have this property if the controller 33 supports read idle window programming 34 35- hw-caps-dll-calib-ctrl: Have this property if the controller 36 supports dll calibration control 37 38- hw-caps-ll-interface : Have this property if the controller 39 has a low latency interface and corresponding interrupt events 40 41- hw-caps-temp-alert : Have this property if the controller 42 has capability for generating SDRAM temperature alerts 43 44Example: 45 46emif1: emif@0x4c000000 { 47 compatible = "ti,emif-4d"; 48 ti,hwmods = "emif2"; 49 phy-type = <1>; 50 device-handle = <&elpida_ECB240ABACN>; 51 cs1-used; 52 hw-caps-read-idle-ctrl; 53 hw-caps-ll-interface; 54 hw-caps-temp-alert; 55}; 56
