* Qualcomm Technologies, Inc. MSM Camera JPEG
|
||||
|
||||
The MSM camera JPEG devices are implemented multiple device nodes.
|
||||
The root JPEG device node has properties defined to hint the driver
|
||||
about the number of Encoder and DMA nodes available during the
|
||||
probe sequence. Each node has multiple properties defined
|
||||
for interrupts, clocks and regulators.
|
||||
|
||||
=======================
|
||||
Required Node Structure
|
||||
=======================
|
||||
JPEG root interface node takes care of the handling account for number
|
||||
of Encoder and DMA devices present on the hardware.
|
||||
|
||||

||||
Value type: <string>
|
||||

|
||||
|
||||
- compat-hw-name
|
||||
Usage: required
|
||||
Value type: <string>

- num-jpeg-dma
|
||||
Usage: required
|
||||
Value type: <u32>
|
||||
Definition: Number of supported DMA HW blocks.
|
||||
|
||||
Example:
|
||||
qcom,cam-jpeg {
|
||||
compatible = "qcom,cam-jpeg";
|
||||
compat-hw-name = "qcom,jpegenc",
|
||||
"qcom,jpegdma";
|
||||
num-jpeg-enc = <1>;
|
||||
num-jpeg-dma = <1>;
|
||||
status = "ok";
|
||||
};
|
||||
|
||||
|
||||
=======================
|
||||
Required Node Structure
|
||||

||||
Encoder/DMA Nodes provide interface for JPEG driver about
|
||||
the device register map, interrupt map, clocks and regulators.

||||
Compatible string definition should be based on target.
