dt: bindings: move SEC node under new crypto/
Since technically it's not powerpc arch-specific. Also rename it sec2 to differentiate it from its incompatible successor, the SEC 4. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

-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>;
- };
