When output queue fourcc is set to any flavour of YUV, the V4L2_CID_JPEG_CHROMA_SUBSAMPLING control value as well as its in-driver cached counterpart have to be updated with the subsampling property of the format so as to be able to provide correct information to the user space and preclude setting an illegal subsampling mode for Exynos4x12 encoder.

Adjust capture format to the Exynos4x12 device limitations, according to the subsampling value parsed from the source JPEG image header. If the capture format was set to YUV with subsampling lower than the one of the source JPEG image the decoding process would not succeed. Signed-off-by:

Make s5p_jpeg_parse_hdr function capable of parsing "YCbCr subsampling" field of a jpeg file header. Store the parsed value in the context. The information about source JPEG subsampling is required to make validation of destination format possible, which must be conducted for exynos4x12 device as the decoding process will not succeed if the destination format is set to YUV with subsampling lower than the one of the source JPEG image. With this knowledge the driver can adjust the destination format appropriately. Signed-off-by:

In the ISI driver it reads the config register to get original value, then set the correct FRATE_DIV and YCC_SWAP_MODE directly. This will cause some bits overlap. So we need to clear these bits first, then set correct value. This patch fix it. Signed-off-by:

The ISI_CFG2.YCC_SWAP field controls color component ordering. The datasheet lists the following orderings for the memory formats. YCC_SWAP Byte 0 Byte 1 Byte 2 Byte 3 00: Default Cb(i) Y(i) Cr(i) Y(i+1) 01: Mode1 Cr(i) Y(i) Cb(i) Y(i+1) 10: Mode2 Y(i) Cb(i) Y(i+1) Cr(i) 11: Mode3 Y(i) Cr(i) Y(i+1) Cb(i) This is based on a sensor format set to CbYCrY (UYVY). The driver hardcodes the output memory format to YUYV, configure the ordering accordingly. Signed-off-by:

ISI_MCK is the sensor master clock. It should be handled by the sensor driver directly, as the ISI has no use for that clock. Make the clock optional here while platforms transition to the correct model. Signed-off-by:

The PCLK and MCK clocks are prepared and unprepared at probe and remove time. Clock (un)preparation isn't needed before enabling/disabling the clocks, and the enable/disable operation happen in non-atomic context. We can thus defer (un)preparation to enable/disable time. Signed-off-by:

when a userspace applications calls the VIDIOC_STREAMON ioctl. The V4L2 core calls the soc_camera_streamon function, which is responsible for starting the video stream. It does so by first starting the atmel-isi host by a call to the vb2_streamon function, and then starting the sensor by a call to the video.s_stream sensor subdev operation. That means we wait for a SOF in start_streaming() before call sensor's s_stream(). It is possible no VSYNC interrupt arrive as the sensor hasn't been started yet. To avoid such case, this patch remove the code to wait for the VSYNC interrupt. And such code is not necessary. Reported-by:

The Si4713 development board contains a Si4713 FM transmitter chip and is handled by the radio-usb-si4713 driver. The board reports itself as (10c4:8244) Cygnal Integrated Products, Inc. and misidentifies itself as a HID device in its USB interface descriptor. This patch ignores this device as an HID device and hence loads the custom driver. Signed-off-by:

In the si4713_tx_tune_power() method, the args array element 'power' can take values between SI4713_MIN_POWER and SI4713_MAX_POWER. power = 0 is also valid. All the values (0 > power < SI4713_MIN_POWER) are illegal and hence are all mapped to SI4713_MIN_POWER. Signed-off-by:
