This change adds device tree probing. There has been an attempt to add device tree support for ov9650 driver by Hugues Fruchet as a part of the patchset that adds support of OV9655 camera (http://www.spinics.net/lists/linux-media/msg117903.html), but it wasn't merged into mainline because creating a separate driver for OV9655 is preferred. This is very similar to Hugues's patch, but not supporting new device. Cc: Jacopo Mondi <jacopo@jmondi.org> Cc: H.

* media: i2c: ov7740: use gpio/consumer.h instead of gpio.hArnd Bergmann2018-01-231-1/+1
| | | | | | | | | | | | | | | | | | When built on a platform without gpiolib support, we run into a couple of compile errors in ov7740, including: drivers/media/i2c/ov7740.c: In function 'ov7740_set_power': drivers/media/i2c/ov7740.c:307:4: error: implicit declaration of function 'gpiod_direction_output'; did you mean 'gpio_direction_output'? [-Werror=implicit-function-declaration] gpiod_direction_output(ov7740->pwdn_gpio, 0); drivers/media/i2c/ov7740.c:914:4: error: 'GPIOD_OUT_HIGH' undeclared (first use in this function); did you mean 'GPIOF_INIT_HIGH'? Changing it to use the correct header file solves the problem.

* media: entity: Add a nop variant of media_entity_cleanupSakari Ailus2018-01-236-20/+0
| | | | | | | | | | | | Add nop variant of media_entity_cleanup. This allows calling media_entity_cleanup whether or not Media controller is enabled, simplifying driver code. Also drop #ifdefs on a few drivers around media_entity_cleanup().

* media: ov5640: fix spurious streamon failuresHugues Fruchet2018-01-231-0/+1
| | | | | | | | | | | | Time to time, stream on is failing with a strange positive error. Error code is returned erroneously by ov5640_set_ctrl_exposure() due to ov5640_get_vts() return value wrongly treated as error. Fix this by forcing ret to 0 after ov5640_get_vts() success call, in order that ret is set to success for rest of code sequence.
