Marvell PXA camera host interface
|
|
|
|
Required properties:
|
|
- compatible: Should be "marvell,pxa270-qci"
|
|
- reg: register base and size
|
|
- interrupts: the interrupt number
|
|
- any required generic properties defined in video-interfaces.txt
|
|
|
|
Optional properties:
|
|
- clocks: input clock (see clock-bindings.txt)
|
|
- clock-output-names: should contain the name of the clock driving the
|
|
sensor master clock MCLK
|
|
- clock-frequency: host interface is driving MCLK, and MCLK rate is this rate
|
|
|
|
Example:
|
|
|
|
pxa_camera: pxa_camera@50000000 {
|
|
compatible = "marvell,pxa270-qci";
|
|
reg = <0x50000000 0x1000>;
|
|
interrupts = <33>;
|
|
|
|
clocks = <&pxa2xx_clks 24>;
|
|
clock-names = "ciclk";
|
|
clock-frequency = <50000000>;
|
|
clock-output-names = "qci_mclk";
|
|
|
|
status = "okay";
|
|
|
|

#size-cells = <0>;
|
|
|
|
/* Parallel bus endpoint */
|

|
|
