1 STMicroelectronics STM32 Digital Camera Memory Interface (DCMI)
3 Required properties:
4 - compatible: "st,stm32-dcmi"
5 - reg: physical base address and length of the registers set for the device
6 - interrupts: should contain IRQ line for the DCMI
7 - resets: reference to a reset controller,
8           see Documentation/devicetree/bindings/reset/st,stm32-rcc.txt
9 - clocks: list of clock specifiers, corresponding to entries in
10           the clock-names property
11 - clock-names: must contain "mclk", which is the DCMI peripherial clock
12 - pinctrl: the pincontrol settings to configure muxing properly
13            for pins that connect to DCMI device.
14            See Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.txt.
15 - dmas: phandle to DMA controller node,
16         see Documentation/devicetree/bindings/dma/stm32-dma.txt
17 - dma-names: must contain "tx", which is the transmit channel from DCMI to DMA
19 DCMI supports a single port node with parallel bus. It should contain one
20 'port' child node with child 'endpoint' node. Please refer to the bindings
21 defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
