Freescale i.MX Media Video Device
|
=================================
|
|
Video Media Controller node
|
---------------------------
|
|
This is the media controller node for video capture support. It is a
|
virtual device that lists the camera serial interface nodes that the
|
media device will control.
|
|
Required properties:
|
- compatible : "fsl,imx-capture-subsystem";
|
- ports : Should contain a list of phandles pointing to camera
|
sensor interface ports of IPU devices
|
|
example:
|
|
capture-subsystem {
|
compatible = "fsl,imx-capture-subsystem";
|
ports = <&ipu1_csi0>, <&ipu1_csi1>;
|
};
|
|
|
mipi_csi2 node
|
--------------
|
|
This is the device node for the MIPI CSI-2 Receiver core in the i.MX
|
SoC. This is a Synopsys Designware MIPI CSI-2 host controller core
|
combined with a D-PHY core mixed into the same register block. In
|
addition this device consists of an i.MX-specific "CSI2IPU gasket"
|
glue logic, also controlled from the same register block. The CSI2IPU
|
gasket demultiplexes the four virtual channel streams from the host
|
controller's 32-bit output image bus onto four 16-bit parallel busses
|
to the i.MX IPU CSIs.
|
|
Required properties:
|
- compatible : "fsl,imx6-mipi-csi2";
|
- reg : physical base address and length of the register set;
|
- clocks : the MIPI CSI-2 receiver requires three clocks: hsi_tx
|
(the D-PHY clock), video_27m (D-PHY PLL reference
|
clock), and eim_podf;
|
- clock-names : must contain "dphy", "ref", "pix";
|
- port@* : five port nodes must exist, containing endpoints
|
connecting to the source and sink devices according to
|
of_graph bindings. The first port is an input port,
|
connecting with a MIPI CSI-2 source, and ports 1
|
through 4 are output ports connecting with parallel
|
bus sink endpoint nodes and correspond to the four
|
MIPI CSI-2 virtual channel outputs.
|
|
Optional properties:
|
- interrupts : must contain two level-triggered interrupts,
|
in order: 100 and 101;
