The real IP under the hood is actually 16*8ccc0d23SEmmanuel Vadot developed by Inside Secure and given to license to vendors. 17*8ccc0d23SEmmanuel Vadot 18*8ccc0d23SEmmanuel Vadot The IP block is sold with different model based on what feature are 19*8ccc0d23SEmmanuel Vadot needed and are identified with the final letter. Each letter correspond 20*8ccc0d23SEmmanuel Vadot to a specific set of feature and multiple letter reflect the sum of the 21*8ccc0d23SEmmanuel Vadot feature set. 22*8ccc0d23SEmmanuel Vadot 23*8ccc0d23SEmmanuel Vadot EIP-93 models: 24*8ccc0d23SEmmanuel Vadot - EIP-93i: (basic) DES/Triple DES, AES, PRNG, IPsec ESP, SRTP, SHA1 25*8ccc0d23SEmmanuel Vadot - EIP-93ie: i + SHA224/256, AES-192/256 26*8ccc0d23SEmmanuel Vadot - EIP-93is: i + SSL/DTLS/DTLS, MD5, ARC4 27*8ccc0d23SEmmanuel Vadot - EIP-93ies: i + e + s 28*8ccc0d23SEmmanuel Vadot - EIP-93iw: i + AES-XCB-MAC, AES-CCM 29*8ccc0d23SEmmanuel Vadot 30*8ccc0d23SEmmanuel Vadotproperties: 31*8ccc0d23SEmmanuel Vadot compatible: 32*8ccc0d23SEmmanuel Vadot oneOf: 33*8ccc0d23SEmmanuel Vadot - items: 34*8ccc0d23SEmmanuel Vadot - const: airoha,en7581-eip93 35*8ccc0d23SEmmanuel Vadot - const: inside-secure,safexcel-eip93ies 36*8ccc0d23SEmmanuel Vadot - items: 37*8ccc0d23SEmmanuel Vadot - not: {} 38*8ccc0d23SEmmanuel Vadot description: Need a SoC specific compatible 39*8ccc0d23SEmmanuel Vadot - enum: 40*8ccc0d23SEmmanuel Vadot - inside-secure,safexcel-eip93i 41*8ccc0d23SEmmanuel Vadot - inside-secure,safexcel-eip93ie 42*8ccc0d23SEmmanuel Vadot - inside-secure,safexcel-eip93is 43*8ccc0d23SEmmanuel Vadot - inside-secure,safexcel-eip93iw 44*8ccc0d23SEmmanuel Vadot 45*8ccc0d23SEmmanuel Vadot reg: 46*8ccc0d23SEmmanuel Vadot maxItems: 1 47*8ccc0d23SEmmanuel Vadot 48*8ccc0d23SEmmanuel Vadot interrupts: 49*8ccc0d23SEmmanuel Vadot maxItems: 1 50*8ccc0d23SEmmanuel Vadot 51*8ccc0d23SEmmanuel Vadotrequired: 52*8ccc0d23SEmmanuel Vadot - compatible 53*8ccc0d23SEmmanuel Vadot - reg 54*8ccc0d23SEmmanuel Vadot - interrupts 55*8ccc0d23SEmmanuel Vadot 56*8ccc0d23SEmmanuel VadotadditionalProperties: false 57*8ccc0d23SEmmanuel Vadot 58*8ccc0d23SEmmanuel Vadotexamples: 59*8ccc0d23SEmmanuel Vadot - | 60*8ccc0d23SEmmanuel Vadot #include <dt-bindings/interrupt-controller/arm-gic.h> 61*8ccc0d23SEmmanuel Vadot 62*8ccc0d23SEmmanuel Vadot crypto@1e004000 { 63*8ccc0d23SEmmanuel Vadot compatible = "airoha,en7581-eip93", "inside-secure,safexcel-eip93ies"; 64*8ccc0d23SEmmanuel Vadot reg = <0x1fb70000 0x1000>; 65*8ccc0d23SEmmanuel Vadot 66*8ccc0d23SEmmanuel Vadot interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_HIGH>; 67*8ccc0d23SEmmanuel Vadot }; 68
