K3 SoC SA2UL crypto module

Required properties:

- compatible : Should be:
  - "ti,sa2ul-crypto"
- reg : Offset and length of the register set for the module

- dmas: DMA specifiers for tx and rx dma. sa2ul needs one tx channel
	and 2 rx channels. First rx channel for < 256 bytes and
	the other one for >=256 bytes. See the DMA client binding,
        Documentation/devicetree/bindings/dma/dma.txt
- dma-names: DMA request names has to have one tx and 2 rx names
	corresponding to dmas abive.
- ti,psil-config* - UDMA PSIL native Peripheral using packet mode.
	SA2UL must have EPIB(Extended protocal information block)
	and PSDATA(protocol specific data) properties.

Example AM654 SA2UL:
crypto: crypto@4E00000 {
	compatible = "ti,sa2ul-crypto";
	reg = <0x0 0x4E00000 0x0 0x1200>;
	ti,psil-base = <0x4000>;

	dmas = <&main_udmap &crypto 0 UDMA_DIR_TX>,
		<&main_udmap &crypto 0 UDMA_DIR_RX>,
		<&main_udmap &crypto 1 UDMA_DIR_RX>;
	dma-names = "tx", "rx1", "rx2";

	ti,psil-config0 {
		linux,udma-mode = <UDMA_PKT_MODE>;
		ti,needs-epib;
		ti,psd-size = <64>;
	};

	ti,psil-config1 {
		linux,udma-mode = <UDMA_PKT_MODE>;
		ti,needs-epib;
		ti,psd-size = <64>;
	};

	ti,psil-config2 {
		linux,udma-mode = <UDMA_PKT_MODE>;
		ti,needs-epib;
		ti,psd-size = <64>;
	};
};
