[PATCH v2] staging: atomisp: add a driver for ov5648 camera sensor
The ov5648 5-megapixel camera sensor from OmniVision supports up to 2592x1944
resolution and MIPI CSI-2 interface. Output format is raw sRGB/Bayer with
10 bits per colour (SGRBG10_1X10).
This patch is a port of ov5648 driver after applying following
01org/ProductionKernelQuilts patches:
- 0004-ov2680-ov5648-Fork-lift-source-from-CTS.patch
- 0005-ov2680-ov5648-gminification.patch

- 0021-MALATA-Fix-testCameraToSurfaceTextureMetadata-CTS.patch
- 0023-OV5648-Added-5MP-video-resolution.patch
New changes introduced during the port:
- Rename entity types to entity functions
- Replace v4l2_subdev_fh by v4l2_subdev_pad_config
- Make use of media_bus_format enum
- Rename media_entity_init function to media_entity_pads_init
- Replace try_mbus_fmt by set_fmt
- Replace s_mbus_fmt by set_fmt
- Replace g_mbus_fmt by get_fmt
- Use s_ctrl/g_volatile_ctrl instead of ctrl core ops
- Update gmin platform API path
- Constify acpi_device_id
- Add "INT5648" value to acpi_device_id
- Fix some checkpatch errors and warnings
- Remove FSF's mailing address from the sample GPL notice
Changes in v2:
- Fix indentation
- Add atomisp prefix to Kconfig option
"INT5648" ACPI device id can be found in following production hardware:

I was not able to properly test this patch on my Lenovo Miix 310 due to other
issues with atomisp, the output is the same as ov2680 driver (OVTI2680)
which is very similar.
