9SEC 6 Node
10
11Description
12
13    Node defines the base address of the SEC 6 block.
14    This block specifies the address range of all global
15    configuration registers for the SEC 6 block.
16    For example, In C293, we could see three SEC 6 node.

61EXAMPLE
62	crypto@a0000 {
63		compatible = "fsl,sec-v6.0";
64		fsl,sec-era = <6>;
65		#address-cells = <1>;

71=====================================================================
72Job Ring (JR) Node
73
74    Child of the crypto node defines data processing interface to SEC 6
75    across the peripheral bus for purposes of processing
76    cryptographic descriptors. The specified address
77    range can be made visible to one (or more) cores.
78    The interrupt defined for this node is controlled within
79    the address range of this node.
80
81  - compatible
82      Usage: required
83      Value type: <string>
84      Definition: Must include "fsl,sec-v6.0-job-ring".
85
86  - reg
87      Usage: required
88      Value type: <prop-encoded-array>
89      Definition: Specifies a two JR parameters:  an offset from
90           the parent physical address and the length the JR registers.
91
92   - interrupts
93      Usage: required
94      Value type: <prop_encoded-array>
95      Definition:  Specifies the interrupts generated by this
96           device.  The value of the interrupts property
97           consists of one interrupt specifier. The format
98           of the specifier is defined by the binding document
99           describing the node's interrupt parent.

101EXAMPLE
102	jr@1000 {
103		compatible = "fsl,sec-v6.0-job-ring";
104		reg = <0x1000 0x1000>;
105		interrupts = <49 2 0 0>;

109Full Example
110
111Since some chips may contain more than one SEC, the dtsi contains
112only the node contents, not the node itself.  A chip using the SEC
113should include the dtsi inside each SEC node.  Example:
114
115In qoriq-sec6.0.dtsi:
116
117	compatible = "fsl,sec-v6.0";
118	fsl,sec-era = <6>;
119	#address-cells = <1>;
120	#size-cells = <1>;
121
122	jr@1000 {
123		compatible = "fsl,sec-v6.0-job-ring",
124			     "fsl,sec-v5.2-job-ring",
125			     "fsl,sec-v5.0-job-ring",
126			     "fsl,sec-v4.4-job-ring",
127			     "fsl,sec-v4.0-job-ring";
128		reg	   = <0x1000 0x1000>;
129	};
130
131	jr@2000 {
132		compatible = "fsl,sec-v6.0-job-ring",
133			     "fsl,sec-v5.2-job-ring",
134			     "fsl,sec-v5.0-job-ring",
135			     "fsl,sec-v4.4-job-ring",
136			     "fsl,sec-v4.0-job-ring";
137		reg	   = <0x2000 0x1000>;
138	};
139
140In the C293 device tree, we add the include of public property:
141
142	crypto@a0000 {
143		/include/ "qoriq-sec6.0.dtsi"
144	}
145
146	crypto@a0000 {
147		reg = <0xa0000 0x20000>;
148		ranges = <0 0xa0000 0x20000>;
149
150		jr@1000 {
151			interrupts = <49 2 0 0>;
152		};
153
154		jr@2000 {
155			interrupts = <50 2 0 0>;
156		};
157	};
