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', but the picture is all wrong, but it was like that
without my patches as well so I am bug-compatible.
I've asked Frank Schaefer who authored this if he can test this em28xx code
and see if something regressed.
The last two patches add isi support to the DT: the first for the ov7670
sensor, the second modifies it for the ov2640 sensor.
These two final patches are for demonstration purposes only, I do not plan
on merging them.
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 believe I have addressed all comments made by Sakari regarding the v1
patch series.
Regards,
Hans
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.
Hans Verkuil (16):
ov7670: call v4l2_async_register_subdev
ov7670: fix g/s_parm
ov7670: get xclk
ov7670: add devicetree support
ov7670: document device tree bindings
atmel-isi: remove dependency of the soc-camera framework
atmel-isi: move out of soc_camera to atmel
atmel-isi: document device tree bindings
ov2640: convert from soc-camera to a standard subdev sensor driver.
ov2640: enable clock and fix power/reset
ov2640: allow use inside em28xx
ov2640: add MC support
ov2640: update bindings
em28xx: drop last soc_camera link
sama5d3 dts: enable atmel-isi
at91-sama5d3_xplained.dts: select ov2640
