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: must be "ti,dra72-cal"
|
||
|
|
- 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;
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
cal: cal@4845b000 {
