Subject[PATCH v4 0/2] [media] atmel-isc: add driver for Atmel ISC
Date
The Image Sensor Controller driver includes two parts.
1) Driver code to implement the ISC function.
2) Device tree binding documentation, it describes how
to add the ISC in device tree.

Changes in v4:
- Modify the isc clock code since the dt is changed.
- Remove the isc clock nodes.

Changes in v3:
- Add pm runtime feature.
- Modify the isc clock code since the dt is changed.
- Remove the 'atmel,sensor-preferred'.
- Modify the isc clock node according to the Rob's remarks.

Changes in v2:
- Add "depends on COMMON_CLK" and "VIDEO_V4L2_SUBDEV_API"
in Kconfig file.
- Correct typos and coding style according to Laurent's remarks
- Delete the loop while in 'isc_clk_enable' function.
- Add the code to support VIDIOC_CREATE_BUFS in
'isc_queue_setup' function.
- Invoke isc_config to configure register in
'isc_start_streaming' function.
- Add the struct completion 'comp' to synchronize with
the frame end interrupt in 'isc_stop_streaming' function.
- Check the return value of the clk_prepare_enable
in 'isc_open' function.
- Set the default format in 'isc_open' function.
- Add an exit condition in the loop while in 'isc_config'.
- Delete the hardware setup operation in 'isc_set_format'.
- Refuse format modification during streaming
in 'isc_s_fmt_vid_cap' function.
- Invoke v4l2_subdev_alloc_pad_config to allocate and
initialize the pad config in 'isc_async_complete' function.
- Remove the '.owner = THIS_MODULE,' in atmel_isc_driver.
- Replace the module_platform_driver_probe() with
module_platform_driver().
- Remove the unit address of the endpoint.
- Add the unit address to the clock node.
- Avoid using underscores in node names.
- Drop the "0x" in the unit address of the i2c node.
- Modify the description of 'atmel,sensor-preferred'.
- Add the description for the ISC internal clock.
