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

-Example:
-
- dcmi: dcmi@50050000 {
- compatible = "st,stm32-dcmi";
- reg = <0x50050000 0x400>;
- interrupts = <78>;
- resets = <&rcc STM32F4_AHB2_RESET(DCMI)>;
- clocks = <&rcc 0 STM32F4_AHB2_CLOCK(DCMI)>;
- clock-names = "mclk";
- pinctrl-names = "default";
- pinctrl-0 = <&dcmi_pins>;
- dmas = <&dma2 1 1 0x414 0x3>;
- dma-names = "tx";
- port {
- dcmi_0: endpoint {
- remote-endpoint = <...>;
- bus-width = <8>;
- hsync-active = <0>;
- vsync-active = <0>;
- pclk-sample = <1>;
