Subject: [PATCH v2] dt-bindings: crypto: Convert stm32 HASH bindings to json-schema
Date: Fri, 15 Nov 2019 11:24:27 +0100 [thread overview]
Message-ID: <20191115102427.31224-1-benjamin.gaignard@st.com> (raw)
Convert the STM32 HASH binding to DT schema format using json-schema
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com>

-* STMicroelectronics STM32 HASH
-
-Required properties:
-- compatible: Should contain entries for this and backward compatible
- HASH versions:
- - "st,stm32f456-hash" for stm32 F456.
- - "st,stm32f756-hash" for stm32 F756.
-- reg: The address and length of the peripheral registers space
-- interrupts: the interrupt specifier for the HASH
-- clocks: The input clock of the HASH instance
-
-Optional properties:
-- resets: The input reset of the HASH instance
-- dmas: DMA specifiers for the HASH. See the DMA client binding,
- Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: DMA request name. Should be "in" if a dma is present.
-- dma-maxburst: Set number of maximum dma burst supported
-
-Example:
-
-hash1: hash@50060400 {
- compatible = "st,stm32f756-hash";
- reg = <0x50060400 0x400>;
- interrupts = <80>;
- clocks = <&rcc 0 STM32F7_AHB2_CLOCK(HASH)>;
- resets = <&rcc STM32F7_AHB2_RESET(HASH)>;
- dmas = <&dma2 7 2 0x400 0x0>;
- dma-names = "in";
- dma-maxburst = <0>;
-};
