2018-05-25media: i2c: adv748x: Fix pixel rate valuesLaurent Pinchart
The pixel rate, as reported by the V4L2_CID_PIXEL_RATE control, must include both horizontal and vertical blanking. Both the AFE and HDMI receiver program it incorrectly: - The HDMI receiver goes to the trouble of removing blanking to compute the rate of active pixels. This is easy to fix by removing the computation and returning the incoming pixel clock rate directly. - The AFE performs similar calculation, while it should simply return the fixed pixel rate for analog sources, mandated by the ADV748x to be 14.3180180 MHz.

This driver is currently specifying a vb2_queue lock, which means it straightforward to implement wait_prepare and wait_finish. Having these callbacks releases the queue lock while blocking, which improves latency by allowing for example streamoff or qbuf operations while waiting in dqbuf.

2018-05-17media: imx274: remove unused data from struct imx274_frmfmtLuca Ceresoli
struct imx274_frmfmt is instantiated only in the imx274_formats[] array, where imx274_formats[N].mode always equals N (via enum imx274_mode). So .mode carries no information, and unsurprisingly it is never used. mbus_code is never used because the 12 bit modes are not implemented. The colorspace member is also never used, which is normal since the imx274 sensor can output only one colorspace. Let's get rid of all of them.

2018-05-17media: smiapp: fix timeout checking in smiapp_read_nvmColin Ian King
The current code decrements the timeout counter i and the end of each loop i is incremented, so the check for timeout will always be false and hence the timeout mechanism is just a dead code path. Potentially, if the RD_READY bit is not set, we could end up in an infinite loop. Fix this so the timeout starts from 1000 and decrements to zero, if at the end of the loop i is zero we have a timeout condition.

2018-05-17media: ov2640: make set_fmt() work in power-down modeAkinobu Mita
The set_fmt() subdev pad operation for this driver currently does not only do the driver internal format selection but also do the actual register setup. This doesn't work if the device power control via GPIO lines is enabled. Because the set_fmt() can be called when the device is placed into power down mode. First of all, this fix adds flag to keep track of whether the device starts streaming or not. Then, the set_fmt() postpones applying the actual register setup at this time.

Computing CRCs on input frames is possible by positioning the DISCOM at a different point in the pipeline.

2018-05-17media: v4l: vsp1: Add support for the DISCOM entityLaurent Pinchart
The DISCOM calculates a CRC on a configurable window of the frame. It interfaces to the VSP through the UIF glue, hence the name used in the code. The module supports configuration of the CRC window through the crop rectangle on the sink pad of the corresponding entity. However, unlike the traditional V4L2 subdevice model, the crop rectangle does not influence the format on the source pad. Modeling the DISCOM as a sink-only entity would allow adhering to the V4L2 subdevice model at the expense of more complex code in the driver, as at the hardware level the UIF is handled as a sink+source entity. As the DISCOM is only present in R-Car Gen3 VSP-D and VSP-DL instances it is not exposed to userspace through V4L2 but controlled through the DU driver. We can thus change this model later if needed without fear of affecting userspace.
