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 {
|
|
compatible = "ti,dra72-cal";
|
|
ti,hwmods = "cal";
|
|
reg = <0x4845B000 0x400>,
|
|
<0x4845B800 0x40>,
|
|
<0x4845B900 0x40>,
|
|
<0x4A002e94 0x4>;
|
|
reg-names = "cal_top",
|
|
"cal_rx_core0",
|
|
"cal_rx_core1",
|
|
"camerrx_control";
|
|
interrupts = <GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH>;
