Description:
d3cold_allowed is bit to control whether the corresponding PCI
device can be put into D3Cold state. If it is cleared, the
device will never be put into D3Cold state. If it is set, the
device may be put into D3Cold state if other requirements are
satisfied too. Reading this attribute will show the current
value of d3cold_allowed bit. Writing this attribute will set
the value of d3cold_allowed bit.

* EMIF family of TI SDRAM controllers

EMIF - External Memory Interface - is an SDRAM controller used in
TI SoCs. EMIF supports, based on the IP revision, one or more of
DDR2/DDR3/LPDDR2 protocols. This binding describes a given instance
of the EMIF IP and memory parts attached to it.

Required properties:
- compatible : Should be of the form "ti,emif-<ip-rev>" where <ip-rev>
is the IP revision of the specific EMIF instance.

- phy-type : <u32> indicating the DDR phy type. Following are the
allowed values
<1> : Attila PHY
<2> : Intelli PHY

- device-handle : phandle to a "lpddr2" node representing the memory part

- ti,hwmods : For TI hwmods processing and omap device creation
the value shall be "emif<n>" where <n> is the number of the EMIF
instance with base 1.

Optional properties:
- cs1-used : Have this property if CS1 of this EMIF
instance has a memory part attached to it. If there is a memory
part attached to CS1, it should be the same type as the one on CS0,
so there is no need to give the details of this memory part.

- cal-resistor-per-cs : Have this property if the board has one
calibration resistor per chip-select.

- hw-caps-read-idle-ctrl: Have this property if the controller
supports read idle window programming

- hw-caps-dll-calib-ctrl: Have this property if the controller
supports dll calibration control

- hw-caps-ll-interface : Have this property if the controller
has a low latency interface and corresponding interrupt events

- hw-caps-temp-alert : Have this property if the controller
has capability for generating SDRAM temperature alerts

Example:

emif1: emif@0x4c000000 {
compatible = "ti,emif-4d";
ti,hwmods = "emif2";
phy-type = <1>;
device-handle = <&elpida_ECB240ABACN>;
cs1-used;
hw-caps-read-idle-ctrl;
hw-caps-ll-interface;
hw-caps-temp-alert;
