From: Hans Verkuil <hans.verkuil@xxxxxxxxx>
This patch series converts the soc-camera atmel-isi to a standalone V4L2
driver.
The same is done for the ov7670 and ov2640 sensor drivers: the ov7670 was
used to test the atmel-isi driver. The ov2640 is needed because the em28xx
driver has a soc_camera include dependency. Both ov7670 and ov2640 sensors
have been tested with the atmel-isi driver.
The first 5 patches improve the ov7670 sensor driver, mostly adding modern
features such as DT support.
The next three convert the atmel-isi and move it out of soc_camera.
The following 6 patches convert ov2640 and drop the soc_camera dependency
in em28xx. I have tested that this works with my 'SpeedLink Vicious And
Divine Laplace webcam'.
Tested with my sama5d3-Xplained board, the ov2640 sensor and two ov7670
sensors: one with and one without reset/pwdn pins. Also tested with my
em28xx-based webcam.
I'd like to get this in for 4.12. Fingers crossed.
Regards,
Hans
Changes since v5:
- Dropped the last two dts patches as these were for demonstration purposes
only.
- Simplified isi_graph_init() return handling as suggested by Sakari.
- Simplified atmel-isi format handling as suggested by Guennadi. Thanks for
the suggestion, this improves the code nicely!
- Improved RGB handling in atmel-isi, allowing for all YUV ordering and not
just YUYV. Tested with YUYV and UYVY (the only two I can test with my
hardware).
- Improved commit message of the "atmel-isi: document device tree bindings"
patch and dropped unnecessary properties from the example as per Rob's
comments.
Changes since v4:
- the ov2640 colorspace fixes were inexplicably part of an atmel-isi patch.
Split it off as a separate patch.
- add V4L2_SUBDEV_FL_HAS_DEVNODE to ov2640.
- drop #if defined(CONFIG_MEDIA_CONTROLLER) guard around media_entity_cleanup
in ov2640.
Changes since v3:
- ov2640/ov7670: call clk_disable_unprepare where needed. I assumed this was
done by the devm_clk_get cleanup, but that wasn't the case.
- bindings: be even more explicit about which properties are mandatory.
- ov2640/ov7670: drop unused bus-width from the dts binding examples and from
the actual dts patches.
Changes since v2:
- Incorporated Sakari's and Rob's device tree bindings comments.
- ov2640: dropped the reset/power changes. These actually broke the em28xx
and there was really nothing wrong with it.
- merged the "ov2640: allow use inside em28xx" into patches 10 and 11.
It really shouldn't have been a separate patch in the first place.
- rebased on top of 4.11-rc1.
Changes since v1:
- Dropped MC support from atmel-isi and ov7670: not needed to make this
work. Only for the ov2640 was it kept since the em28xx driver requires it.
- Use devm_clk_get instead of clk_get.
- The ov7670 lower limit of the clock speed is 10 MHz instead of 12. Adjust
accordingly.
