+Freescale SoC SEC Security Engines
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+ SEC versions, high to low, e.g., "fsl,sec2.1", "fsl,sec2.0"
+- reg : Offset and length of the register set for the device
+- interrupts : the SEC's interrupt number
+- fsl,num-channels : An integer representing the number of channels
+ available.
+- fsl,channel-fifo-len : An integer representing the number of
+ descriptor pointers each channel fetch fifo can hold.
+- fsl,exec-units-mask : The bitmask representing what execution units
+ (EUs) are available. It's a single 32-bit cell. EU information
+ should be encoded following the SEC's Descriptor Header Dword
+ EU_SEL0 field documentation, i.e. as follows:
+
+ bit 0 = reserved - should be 0
+ bit 1 = set if SEC has the ARC4 EU (AFEU)
+ bit 2 = set if SEC has the DES/3DES EU (DEU)
+ bit 3 = set if SEC has the message digest EU (MDEU/MDEU-A)
+ bit 4 = set if SEC has the random number generator EU (RNG)
+ bit 5 = set if SEC has the public key EU (PKEU)
+ bit 6 = set if SEC has the AES EU (AESU)
+ bit 7 = set if SEC has the Kasumi EU (KEU)
+ bit 8 = set if SEC has the CRC EU (CRCU)
+ bit 11 = set if SEC has the message digest EU extended alg set (MDEU-B)
+
+remaining bits are reserved for future SEC EUs.
+
+- fsl,descriptor-types-mask : The bitmask representing what descriptors
+ are available. It's a single 32-bit cell. Descriptor type information
+ should be encoded following the SEC's Descriptor Header Dword DESC_TYPE
+ field documentation, i.e. as follows:
+
+ bit 0 = set if SEC supports the aesu_ctr_nonsnoop desc. type
+ bit 1 = set if SEC supports the ipsec_esp descriptor type
+ bit 2 = set if SEC supports the common_nonsnoop desc. type
+ bit 3 = set if SEC supports the 802.11i AES ccmp desc. type
+ bit 4 = set if SEC supports the hmac_snoop_no_afeu desc. type
+ bit 5 = set if SEC supports the srtp descriptor type
+ bit 6 = set if SEC supports the non_hmac_snoop_no_afeu desc.type
+ bit 7 = set if SEC supports the pkeu_assemble descriptor type
+ bit 8 = set if SEC supports the aesu_key_expand_output desc.type
+ bit 9 = set if SEC supports the pkeu_ptmul descriptor type
+ bit 10 = set if SEC supports the common_nonsnoop_afeu desc. type
+ bit 11 = set if SEC supports the pkeu_ptadd_dbl descriptor type
+
+ ..and so on and so forth.
+
+Optional properties:
+
+- interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+Example:
+
+ /* MPC8548E */
+ crypto@30000 {
+ compatible = "fsl,sec2.1", "fsl,sec2.0";
+ reg = <0x30000 0x10000>;
+ interrupts = <29 2>;
+ interrupt-parent = <&mpic>;
+ fsl,num-channels = <4>;
+ fsl,channel-fifo-len = <24>;
+ fsl,exec-units-mask = <0xfe>;
+ fsl,descriptor-types-mask = <0x12b0ebf>;
+ };
