-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>;
-        };
