Use the %zu and %pad printk specifiers to print size_t and dma_addr_t variables. This fixes warnings on platforms where dma_addr_t has a different size than int. Cc: Guennadi Liakhovetski <g.liakhovetski@gmx.de> 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:

si4713_set_rds_radio_text will overwrite the terminating zero at the end of the rds radio text string in order to send out a carriage return as per the RDS spec. Use a separate char buffer for the CR instead of corrupting the control string. Signed-off-by:

Dinesh Ram authored
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:

The clock core code is going to be modified so clk_get() takes reference on the clock provider module. Until the potential circular reference issue is properly addressed, we pass NULL as the first argument to clk_register(), in order to disallow sub-devices taking a reference on the ISP module back trough clk_get(). This should prevent locking the modules in memory. Signed-off-by:

Standard suspend/resume path is called after runtime resume of the given device, so suspend/resume callbacks must do all clock management done also by runtime pm to allow for proper power domain shutdown. Moreover, JPEG clock is enabled from probe function but is is not necessary. This patch also moves control of jpeg clock to runtime_pm callbacks. Signed-off-by:

Aligning capture queue image dimensions while enqueuing output queue doesn't make a sense as the S_FMT ioctl might have not been called for the capture queue until that moment, whereas it is required to know capture format as the type of alignment heavily depends on it. Signed-off-by:

The aim of the condition is ensuring that the bytesperline value set by the user space application is proper for the given format and adjusting it if isn't. As the depth value of the format description entry is expressed in bits then the bytesperline value needs to be divided, not multiplied, by that value to get the number of bytes required to store single line of image samples.

Reorder quantization tables so that their elements are arranged in the manner reflecting compression quality level that is in accordance with V4L2 documentation, i.e. the larger value of the V4L2_CID_JPEG_COMPRESSION_QUALITY control the better image quality, and thus lower compression quality. The modification allows also to get rid of reverse logic in the s_ctrl callback while assigning user space value to the ctx->compr_quality variable. Signed-off-by:
