1 * EMIF family of TI SDRAM controllers
3 EMIF - External Memory Interface - is an SDRAM controller used in
4 TI SoCs. EMIF supports, based on the IP revision, one or more of
5 DDR2/DDR3/LPDDR2 protocols. This binding describes a given instance
6 of the EMIF IP and memory parts attached to it.
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 For am437x should be ti,emif-am4372.
13 - phy-type : <u32> indicating the DDR phy type. Following are the
18 - device-handle : phandle to a "lpddr2" node representing the memory part
20 - ti,hwmods : For TI hwmods processing and omap device creation
21 the value shall be "emif<n>" where <n> is the number of the EMIF
25 - cs1-used : Have this property if CS1 of this EMIF
26 instance has a memory part attached to it. If there is a memory
27 part attached to CS1, it should be the same type as the one on CS0,
28 so there is no need to give the details of this memory part.
30 - cal-resistor-per-cs : Have this property if the board has one
31 calibration resistor per chip-select.
33 - hw-caps-read-idle-ctrl: Have this property if the controller
34 supports read idle window programming
36 - hw-caps-dll-calib-ctrl: Have this property if the controller
37 supports dll calibration control
39 - hw-caps-ll-interface : Have this property if the controller
40 has a low latency interface and corresponding interrupt events
42 - hw-caps-temp-alert : Have this property if the controller
43 has capability for generating SDRAM temperature alerts
