-* Allwinner Security System found on A20 SoC
-
-Required properties:
-- compatible : Should be "allwinner,sun4i-a10-crypto".
-- reg: Should contain the Security System register location and length.
-- interrupts: Should contain the IRQ line for the Security System.
-- clocks : List of clock specifiers, corresponding to ahb and ss.
-- clock-names : Name of the functional clock, should be
- * "ahb" : AHB gating clock
- * "mod" : SS controller clock
-
-Optional properties:
- - resets : phandle + reset specifier pair
- - reset-names : must contain "ahb"
-
-Example:
- crypto: crypto-engine@1c15000 {
- compatible = "allwinner,sun4i-a10-crypto";
- reg = <0x01c15000 0x1000>;
- interrupts = <GIC_SPI 86 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&ahb_gates 5>, <&ss_clk>;
- clock-names = "ahb", "mod";
- };
The older Allwinner SoCs have a crypto engine that is supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.
