OMAP4 ISS Driver |
|
================ |
|
|
|
Introduction |
|
------------ |
|
|
|
The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS), |
|
Which contains several components that can be categorized in 3 big groups: |
|
|
|
- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2) |
|
- ISP (Image Signal Processor) |
|
- SIMCOP (Still Image Coprocessor) |
|
|
|
For more information, please look in [1] for latest version of: |
|
"OMAP4430 Multimedia Device Silicon Revision 2.x" |
|
|
|
As of Revision AB, the ISS is described in detail in section 8. |
|
|
|
This driver is supporting _only_ the CSI2-A/B interfaces for now. |
|
|
|
It makes use of the Media Controller framework [2], and inherited most of the |
|
code from OMAP3 ISP driver (found under drivers/media/platform/omap3isp/*), |
|
except that it doesn't need an IOMMU now for ISS buffers memory mapping. |
|
|
|
Supports usage of MMAP buffers only (for now). |
|
|
|
Tested platforms |
|
---------------- |
|
|
|
- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in |
|
which only the last one is supported, outputting YUV422 frames). |
|
|
|
- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in |
|
which only the OV5650 are supported, outputting RAW10 frames). |
|
|
|
