5 wireless and mobile applications that use low-power technology.
11  - compatible:		Should contain one of the following:
12 			  "fsl,imx1-weim"
13 			  "fsl,imx27-weim"
14 			  "fsl,imx51-weim"
15 			  "fsl,imx50-weim"
16 			  "fsl,imx6q-weim"
17  - reg:			A resource specifier for the register space
19  - clocks:		the clock, see the example below.
20  - #address-cells:	Must be set to 2 to allow memory address translation
21  - #size-cells:		Must be set to 1 to allow CS address passing
22  - ranges:		Must be set up to reflect the memory layout with four
23 			integer values for each chip-select line in use:
25 			   <cs-number> 0 <physical address of mapping> <size>
29  - fsl,weim-cs-gpr:	For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
30 			devices, it should be the phandle to the system General
31 			Purpose Register controller that contains WEIM CS GPR
34 			values depending on the CS space configuration.
37 			---------------------------------------------
47  - fsl,burst-clk-enable	For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
51  - fsl,continuous-burst-clk	Make Burst Clock to output continuous clock.
54 			"fsl,burst-clk-enable" is set.
58  - fsl,weim-cs-timing:	The timing array, contains timing values for the
59 			child node. We get the CS indexes from the address
62 			For i.MX1, i.MX21 ("fsl,imx1-weim") there are two
64 			For i.MX25, i.MX27, i.MX31 and i.MX35 ("fsl,imx27-weim")
66 			For i.MX50, i.MX53 ("fsl,imx50-weim"),
67 			i.MX51 ("fsl,imx51-weim") and i.MX6Q ("fsl,imx6q-weim")
71 Example for an imx6q-sabreauto board, the NOR flash connected to the WEIM:
74 		compatible = "fsl,imx6q-weim";
77 		#address-cells = <2>;
78 		#size-cells = <1>;
80 		fsl,weim-cs-gpr = <&gpr>;
83 			compatible = "cfi-flash";
85 			#address-cells = <1>;
86 			#size-cells = <1>;
87 			bank-width = <2>;
88 			fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
93 Example for an imx6q-based board, a multi-chipselect device connected to WEIM:
99 		compatible = "fsl,imx6q-weim";
102 		#address-cells = <2>;
103 		#size-cells = <1>;
108 		fsl,weim-cs-gpr = <&gpr>;
114 			fsl,weim-cs-timing = <0x024400b1 0x00001010 0x20081100
