1 Atmel Image Sensor Interface (ISI)
2 ----------------------------------
3
4 Required properties for ISI:
5 - compatible: must be "atmel,at91sam9g45-isi"
6 - reg: physical base address and length of the
7 - interrupts: should contain IRQ line for the
8 - clocks: list of clock specifiers, correspond
9 property; please refer to clock-bindin
10 - clock-names: required elements: "isi_clk".
11 - pinctrl-names, pinctrl-0: please refer to pi
12
13 ISI supports a single port node with parallel
14 'port' child node with child 'endpoint' node.
15 defined in Documentation/devicetree/bindings/m
16
17 Endpoint node properties
18 ------------------------
19
20 - bus-width: <8> or <10> (mandatory)
21 - hsync-active (default: active high)
22 - vsync-active (default: active high)
23 - pclk-sample (default: sample on falling edge
24 - remote-endpoint: A phandle to the bus receiv
