The Camera Adaptation Layer (CAL) is a key component for image capture
|
||||||
|
applications. The capture module provides the system interface and the
|
||||||
|
processing capability to connect CSI2 image-sensor modules to the
|
||||||
|
DRA72x device.
|
||||||
|
|
||||||
|
CAL supports 2 camera port nodes on MIPI bus. Each CSI2 camera port nodes
|
||||||
|
should contain a 'port' child node with child 'endpoint' node. Please
|
||||||
|
refer to the bindings defined in
|
||||||
|
Documentation/devicetree/bindings/media/video-interfaces.txt.

Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL)
|
|
||||||
------------------------------------------------------
|
|
||||||
|
|
||||||
The Camera Adaptation Layer (CAL) is a key component for image capture
|
|
||||||
applications. The capture module provides the system interface and the
|
|
||||||
processing capability to connect CSI2 image-sensor modules to the
|
|
||||||
DRA72x device.
|
|
||||||
|
|
||||||
Required properties:
|
|
||||||
- compatible:
|
|
||||||
Should be "ti,dra72-cal", for DRA72 controllers
|
|
||||||
Should be "ti,dra72-pre-es2-cal", for DRA72 controllers pre ES2.0
|
|
||||||
Should be "ti,dra76-cal", for DRA76 controllers
|
|
||||||
Should be "ti,am654-cal", for AM654 controllers
|
|
||||||
- reg: CAL Top level, Receiver Core #0, Receiver Core #1 and Camera RX
|
|
||||||
control address space
|
|
||||||
- reg-names: cal_top, cal_rx_core0, cal_rx_core1 and camerrx_control
|
|
||||||
registers
|
|
||||||
- interrupts: should contain IRQ line for the CAL;
|
|
||||||
- ti,camerrx-control: phandle to the device control module and offset to
|
|
||||||
the control_camerarx_core register.
|
|
||||||
This node is meant to replace the "camerrx_control"
|
|
||||||
reg entry above but "camerrx_control" is still
|
|
||||||
handled for backward compatibility.
|
|
||||||
|
|
||||||
CAL supports 2 camera port nodes on MIPI bus. Each CSI2 camera port nodes
|
|
||||||
should contain a 'port' child node with child 'endpoint' node. Please
|
|
||||||
