Freescale i.MX Platforms Device Tree Bindings
-----------------------------------------------
i.MX23 Evaluation Kit

Required root node properties:
- compatible = "fsl,imx27-pdk", "fsl,imx27";
i.MX28 Evaluation Kit
Required root node properties:
- compatible = "fsl,imx28-evk", "fsl,imx28";
i.MX51 Babbage Board
Required root node properties:
- compatible = "fsl,imx51-babbage", "fsl,imx51";
i.MX53 Automotive Reference Design Board
Required root node properties:
- compatible = "fsl,imx53-ard", "fsl,imx53";
i.MX53 Evaluation Kit
Required root node properties:
- compatible = "fsl,imx53-evk", "fsl,imx53";
i.MX53 Quick Start Board
Required root node properties:
- compatible = "fsl,imx53-qsb", "fsl,imx53";
i.MX53 Smart Mobile Reference Design Board
Required root node properties:
- compatible = "fsl,imx53-smd", "fsl,imx53";
i.MX6 Quad Armadillo2 Board
Required root node properties:
- compatible = "fsl,imx6q-arm2", "fsl,imx6q";
i.MX6 Quad SABRE Lite Board
Required root node properties:
- compatible = "fsl,imx6q-sabrelite", "fsl,imx6q";
i.MX6 Quad SABRE Smart Device Board
Required root node properties:
- compatible = "fsl,imx6q-sabresd", "fsl,imx6q";
i.MX6 Quad SABRE Automotive Board
Required root node properties:
- compatible = "fsl,imx6q-sabreauto", "fsl,imx6q";
Generic i.MX boards
-------------------
No iomux setup is done for these boards, so this must have been configured
by the bootloader for boards to work with the generic bindings.
i.MX27 generic board
Required root node properties:
- compatible = "fsl,imx27";
i.MX51 generic board
Required root node properties:
- compatible = "fsl,imx51";
i.MX53 generic board
Required root node properties:
- compatible = "fsl,imx53";
i.MX6q generic board
Required root node properties:
- compatible = "fsl,imx6q";
Freescale Vybrid Platform Device Tree Bindings
----------------------------------------------
For the Vybrid SoC familiy all variants with DDR controller are supported,
which is the VF5xx and VF6xx series. Out of historical reasons, in most
places the kernel uses vf610 to refer to the whole familiy.
The compatible string "fsl,vf610m4" is used for the secondary Cortex-M4
core support.
Required root node compatible property (one of them):
- compatible = "fsl,vf500";
- compatible = "fsl,vf510";
- compatible = "fsl,vf600";
- compatible = "fsl,vf610";
- compatible = "fsl,vf610m4";
Freescale LS1021A Platform Device Tree Bindings
------------------------------------------------
Required root node compatible properties:
- compatible = "fsl,ls1021a";
Freescale LS1021A SoC-specific Device Tree Bindings
-------------------------------------------
Freescale SCFG
SCFG is the supplemental configuration unit, that provides SoC specific
configuration and status registers for the chip. Such as getting PEX port
status.
Required properties:
- compatible: should be "fsl,ls1021a-scfg"
- reg: should contain base address and length of SCFG memory-mapped registers
Example:
scfg: scfg@1570000 {
compatible = "fsl,ls1021a-scfg";
reg = <0x0 0x1570000 0x0 0x10000>;
};
Freescale DCFG
DCFG is the device configuration unit, that provides general purpose
configuration and status for the device. Such as setting the secondary
core start address and release the secondary core from holdoff and startup.
Required properties:
- compatible: should be "fsl,ls1021a-dcfg"
- reg : should contain base address and length of DCFG memory-mapped registers
Example:
dcfg: dcfg@1ee0000 {
compatible = "fsl,ls1021a-dcfg";
reg = <0x0 0x1ee0000 0x0 0x10000>;
};
Freescale LS2085A SoC Device Tree Bindings
------------------------------------------
LS2085A ARMv8 based Simulator model
Required root node properties:
- compatible = "fsl,ls2085a-simu", "fsl,ls2085a";
