The isp stat driver allocates memory for DMA and uses GFP_DMA flag for dev_alloc_coherent. The flag is no longer needed as the DMA mask is used for the purpose. Remove it. Reported-by:

The omap3isp driver checked whether the second argument (the new configuration) to the ISP statistics is NULL. This is the pointer to the user-given argument and is never NULL. Remove the check. Reported-by:

C libraries with 64-bit time_t use an incompatible format for struct omap3isp_stat_data. This changes the kernel code to support either version, by moving over the normal handling to the 64-bit variant, and adding compatiblity code to handle the old binary format with the existing ioctl command code. Fortunately, the command code includes the size of the structure, so the difference gets handled automatically. In the process of eliminating the references to 'struct timeval' from the kernel, I also change the way the timestamp is generated internally, basically by open-coding the v4l2_get_timestamp() call.

Since commit 50b0f0ae ("gpu: ipu-csi: add 10/12-bit grayscale support to mbus_code_to_bus_cfg") the IPU CSI can be configured to capture 10-bit and 12-bit grayscale formats, expanded to 16-bit grayscale, in bayer/generic data mode. This patch adds support for V4L2_PIX_FMT_Y16 captured from sensors that provide MEDIA_BUS_FMT_Y10_1X10 or MEDIA_BUS_FMT_Y12_1X12 data. Cc: Jan Luebbe <jlu@pengutronix.de> Signed-off-by:

This issue was reported by a user who downloaded a corrupt saa7164 firmware, then went looking for a valid xc5000 firmware to fix the error displayed...but the device in question has no xc5000, thus after much effort, the wild goose chase eventually led to a support call. The xc5000 has nothing to do with saa7164 (as far as I can tell), so replace the string with saa7164 as well as give a meaningful hint on the firmware mismatch. Signed-off-by:

The renesas-ceu driver intializes the desired mbus_format at 'complete' time, inspecting the supported subdevice ones, and tuning some parameters to produce the requested memory format from what the sensor can produce. Although, the initially selected mbus_format was not provided to the subdevice during set_fmt and try_fmt operations, providing instead a '0' mbus format code. As long as the sensor defaults to a compatible mbus_format when an invalid code as '0' is provided, capture operations work correctly. If the subdevice defaults to an unsupported format (eg. some RGB permutations) capture does not work properly due to a mismatch on the expected and received image format on the wire. Fix that by re-using the initially selected mbus_format code during set_fmt and try_fmt subdevice operation calls. Tested by printing out the format selection procedure with ov7670 sensor.

This reverts commit fc7f8fd4 . Whilst the rationale for the above commit was in general correct, i.e. that users *consuming* the DMA addresses should rely on sglen rather than num_pages, it has always been the case that the DMA API itself still requires that dma_{sync,unmap}_sg() are called with the original number of entries as passed to dma_map_sg(), not the number of mapped entries it returned. Thus the particular changes made in that patch were erroneous. At worst this might lead to data loss at the tail end of mapped buffers on non-coherent hardware, while at best it's an example of incorrect DMA API usage which has proven to mislead readers.

Do not set context colorimetry on the raw (OUTPUT) queue for encoders. Always set colorimetry on the coded queue (CAPTURE for encoders, OUTPUT for decoders).

Replace the manual validity checks for the GPIO with the gpio_is_valid(). In vip_gpio_reserve(), Error checking for gpio pin is not correct. If pwr_pin = -1, It will return 0. This should be return an error. In sta2x11_vip_init_one(), Error checking for gpio 'reset_pin' is unnecessary. Because vip_gpio_reserve() is also checking for valid gpio pin. So removed extra error checking for gpio 'reset_pin'. Signed-off-by:

Interrupt behavior shows that some time the frame end and frame start of next frame is unstable and can range from several to hundreds of micro-sec. In the case of ~10us, isr may not clear next sof interrupt status in single handling, which prevents new interrupts from coming. Fix this by handling all pending IRQs before exiting isr, so any abnormal behavior results from very short interrupt status changes is protected. Signed-off-by:
