| * | media: v4l2-flash-led-class: Create separate sub-devices for indicatorsSakari Ailus2017-08-271-46/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The V4L2 flash interface allows controlling multiple LEDs through a single sub-devices if, and only if, these LEDs are of different types. This approach scales badly for flash controllers that drive multiple flash LEDs or for LED specific associations. Essentially, the original assumption of a LED driver chip that drives a single flash LED and an indicator LED is no longer valid. Address the matter by registering one sub-device per LED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use standard V4L2 control to get pixel clock rate from a sensor linked in the media controller pipeline. Then calculate clock rates on CSIPHY, CSID and VFE to use the lowest possible. If the currnet pixel clock rate of the sensor cannot be read then use the highest possible. This case covers also the CSID test generator usage. If VFE is already powered on by another pipeline, check that the current VFE clock rate is high enough for the new pipeline. If not return busy error code as VFE clock rate cannot be changed while VFE is running.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is intended to give to the v4l2 drivers a choice to change the default behavior of the v4l2-core DMA mapping direction from DMA_TO/FROM_DEVICE (depending on the buffer type CAPTURE or OUTPUT) to DMA_BIDIRECTIONAL during queue_init time. Initially the issue with DMA mapping direction has been found in Venus encoder driver where the hardware (firmware side) adds few lines padding on bottom of the image buffer, and the consequence is triggering of IOMMU protection faults. This will help supporting venus encoder (and probably other drivers in the future) which wants to map output type of buffers as read/write.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implements g_/s_selection crop support by using DCMI crop hardware feature. User can first get the maximum supported resolution of the sensor by calling g_selection(V4L2_SEL_TGT_CROP_BOUNDS). Then user call to s_selection(V4L2_SEL_TGT_CROP) will reset sensor to its maximum resolution and crop request is saved for later usage in s_fmt(). Next call to s_fmt() will check if sensor can do frame size request with crop request. If sensor supports only discrete frame sizes, the frame size which is larger than user request is selected in order to be able to match the crop request. Then s_fmt() resolution user request is adjusted to match crop request resolution.
