ov7670 driver supports two optional properties supplied through platform data, but currently does not support any standard video interface property. Add support through OF parsing for 2 generic properties (vsync and hsync polarities) and for one custom property already supported through platform data to suppress pixel clock output during horizontal blanking. While at there, check return value of register writes in set_fmt function and rationalize spacings. Signal polarities and pixel clock blanking verified through scope and image capture. Signed-off-by:

Describe newly introduced OF properties for ov7670 image sensor. The driver supports two standard properties to configure synchronism signals polarities and one custom property already supported as platform data options to suppress pixel clock during horizontal blankings.

The ov9650 driver currently only supports legacy platform data probe. 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.

Previously, the sensor, with default settings, was outputting SOF without data. This results in frame sync error on the receiver side. Now, configure the sensor to output SOF with MIPI data for all frames. This avoids possible null first frame on the bus. Signed-off-by:

This patch adds driver for Omnivision's ov2685 sensor. Though the ov2685 can output yuv data, this driver only supports the raw bayer format, including the following features: - output 1600x1200 at 30fps - test patterns - manual exposure/gain control - vblank and hblank - media controller - runtime pm [Sakari Ailus: trivial: ov5695_of_match -> ov2685_of_match] Signed-off-by:

This is to avoid pending interrupts to be handled during stream off, in which case, the ready buffer will be removed from buffer list, thus not all buffers can be returned to VB2 as expected. Disable CIO2 irq at cio2_hw_exit() so no new interrupts are generated. Signed-off-by:

Commit 828ee8c7 ("media: uvcvideo: Use ktime_t for timestamps") changed to use ktime_t for timestamps. Older Kernels use a struct for ktime_t, which requires the conversion function ktime_to_ns to be used on some places. With this patch it will compile now also for older Kernel versions.

While the sizeof is an operator and not a function, the preferred coding style in the kernel is to enclose its operand in parentheses. To avoid mixing multiple coding styles in the driver, use parentheses around all sizeof operands. While at it replace a kmalloc() with a kmalloc_array() to silence a checkpatch warning triggered by this patch. Signed-off-by:

Use flags the device exposes for UVC controls. This allows the device to define which property flags are set. Since some cameras offer auto-adjustments for properties (e.g. auto-gain), the values of other properties (e.g. gain) can change in the camera. Examining the flags ensures that the driver is aware of such properties. Signed-off-by:

Remove sensor driver's interface for setting the use case specific mode list as well as the mode lists that are related to other than CI_MODE_PREVIEW. This removes s_parm abuse in using driver specific values in v4l2_streamparm.capture.capturemode. The drivers already support [gs]_frame_interval so removing support for [gs]_parm is enough.
