[PATCH v2] dt-bindings: crypto: Convert ti,omap4-des to DT schema
Posted by Rob Herring (Arm) 4 months ago
Convert the TI OMAP DES binding to DT schema format.

Drop "ti,hwmods" as it is not actually used for this binding. Only
OMAP2 platforms are using it.

Signed-off-by: Rob Herring (Arm) <robh@kernel.org>

v2:
 - Drop ti,hwmods from required too

-OMAP SoC DES crypto Module
-
-Required properties:
-
-- compatible : Should contain "ti,omap4-des"
-- ti,hwmods: Name of the hwmod associated with the DES module
-- reg : Offset and length of the register set for the module
-- interrupts : the interrupt-specifier for the DES module
-- clocks : A phandle to the functional clock node of the DES module
-           corresponding to each entry in clock-names
-- clock-names : Name of the functional clock, should be "fck"
-
-Optional properties:
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-	Documentation/devicetree/bindings/dma/dma.txt
-	Each entry corresponds to an entry in dma-names
-- dma-names: DMA request names should include "tx" and "rx" if present
-
-Example:
-	/* DRA7xx SoC */
-	des: des@480a5000 {
-		compatible = "ti,omap4-des";
-		ti,hwmods = "des";
-		reg = <0x480a5000 0xa0>;
-		interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
-		dmas = <&sdma 117>, <&sdma 116>;
-		dma-names = "tx", "rx";
-		clocks = <&l3_iclk_div>;
-		clock-names = "fck";
-	};
