Subject: [PATCH 2/3] Moorestown Camera Imaging driver Beta 10.0

Patch-mainline: 2.6.35?

Changes from Beta 9.0:
1. Fixed hsd sighting
        3469638 3469639 3469710 3469822 (high)
        3469697 (medium)

Changes from Beta 8.0:
1. Fixed hsd sighting
        3469056 3469058 (critical)
        3469705 3469696 3469709 3469510 (medium)

Changes from Beta 7.0:
1. Fixed hsd sighting 3469681,3469682,3469683 (high)

Changes from Beta 6.0:
1. Fixed hsd sighting 3469668 (high)
2. Fixed ov5630 v4l2 view-finding dark issue
3. Enabled support for popular v4l2 applications (cheese, skype, ffmpeg)

Changes from Beta 5.1:
1. Fixed CRITICAL sighting 3469558 -- ciapp fails to launch with segment fault
2. Fixed HIGH sighting 3479513 -- ov5630 AWB unstable
3. Improved KMOT sensor 720p fps from 30 to 40

Changes from Beta 5.0:
Fixed a critical issue of camera driver not loading -- hsd 3469557

Main changes from Beta 4.0:
Fixed 4 HSD sightings: 3469392,3469099,3469470,3469500

Main changes from Beta 3.0:
Fixed 7 HSD sightings: 3469264,3469112,3469395,3469103,3469105,3469471,3469484

Main changes from Beta 2.0:
Fixed 6 HSD sightings: 3469047,3469315,3469317,3469101,3468409,3469391

Main changes from Beta 1.1:
1. Added interrupt mode for jpeg capture and KMOT viewfinding
2. Fixed HSD sighting 3469228 and 3469147

Main changes from Alpha2:
Enabled MIPI interface in ISP driver and KMOT sensor s5k4e1.
Enabled FIFO in ISP driver, which doubled the fps in view-finding mode.
Enabled Subdev Framework in CI kernel driver.
Enabled AF Continuous Mode.
Enabled AE scene evaluation.

Enabled the camera drivers in kernel:
Device Drivers --> Multimedia support --> Video For Linux
Device Drivers --> Mulitmedia support --> Video capture adapters -->
--> Moorestown Langwell Camera Imaging Subsystem support.

Kernel configs:
1. camera driver depends on GPIO library and I2C driver.
CONFIG_GENERIC_GPIO=y
CONFIG_I2C=y
CONFIG_GPIOLIB=y
2. camera driver depends on videobuf-core and videobuf-dma-contig.
VIDEOBUF_GEN=y
VIDEOBUF_DMA_CONTIG=y
3. enable multimedia support and video capture.
CONFIG_MEDIA_SUPPORT=y
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L2_COMMON=y
CONFIG_VIDEO_MEDIA=y
CONFIG_VIDEO_V4L2=y
4. camera drivers incluing ISP, 5630, 5630-motor, s5k4e1, s5k4e1-motor, 2650,
9665, flash.
CONFIG_VIDEO_MRSTCI=y
CONFIG_VIDEO_MRST_ISP=y
CONFIG_VIDEO_MRST_OV5630=y
CONFIG_VIDEO_MRST_OV5630_MOTOR=y
CONFIG_VIDEO_MRST_S5K4E1=y
CONFIG_VIDEO_MRST_S5K4E1_MOTOR=y
CONFIG_VIDEO_MRST_FLASH=y
CONFIG_VIDEO_MRST_OV2650=y
CONFIG_VIDEO_MRST_OV9665=y
