| * dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO flagsChristoph Hellwig2017-09-011-3/+2
| | | | | | | | | | | | | | | | | | DMA_MEMORY_IO was never used in the tree, so remove it. That means there is no need for the DMA_MEMORY_MAP flag either now, so remove it as well and change dma_declare_coherent_memory to return a normal errno value.

This contains: - A lot of new drivers: * DVB frontends: mxl5xx, stv0910, stv6111; * camera flash: as3645a led driver; * HDMI receiver: adv748X; * camera sensor: Omnivision 6650 5M driver (ov6650); * HDMI CEC: ao-cec meson driver; * V4L2: Qualcom camss driver; * Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers. - The DDbridge DVB driver got a massive update, with makes it in sync with modern hardware from that vendor; - There's an important milestone on this series: the DVB documentation was written in 2003, but only started to be updated in 2007. It also used to contain several gaps from the time it was kept out of tree, mentioning error codes and device nodes that never existed upstream. On this series, it received a massive update: all non-deprecated digital TV APIs are now in sync with the current implementation; - Some DVB APIs that aren't used by any upstream driver got removed; - Other parts of the media documentation algo got updated, fixing some bugs on its PDF output and making it compatible with Sphinx version 1.6. As the number of hacks required to build PDF output reduced, I hope we'll have less troubles as newer versions of our documentation toolchain are released (famous last words); - As usual, lots of driver cleanups and improvements" * tag 'media/v4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (624 commits) media: leds: as3645a: add V4L2_FLASH_LED_CLASS dependency media: get rid of removed DMX_GET_CAPS and DMX_SET_SOURCE leftovers media: Revert "[media] v4l: async: make v4l2 coexist with devicetree nodes in a dt overlay" media: staging: atomisp: sh_css_calloc shall return a pointer to the allocated space media: Revert "[media] lirc_dev: remove superfluous get/put_device() calls" media: add qcom_camss.rst to v4l-drivers rst file media: dvb headers: make checkpatch happier media: dvb uapi: move frontend legacy API to another part of the book media: pixfmt-srggb12p.rst: better format the table for PDF output media: docs-rst: media: Don't use \small for V4L2_PIX_FMT_SRGGB10 documentation media: index.rst: don't write "Contents:" on PDF output media: pixfmt*.rst: replace a two dots by a comma media: vidioc-g-fmt.rst: adjust table format media: vivid.rst: add a blank line to correct ReST format media: v4l2 uapi book: get rid of driver programming's chapter media: format.rst: use the right markup for important notes media: docs-rst: cardlists: change their format to flat-tables media: em28xx-cardlist.rst: update to reflect last changes media: v4l2-event.rst: adjust table to fit on PDF output media: docs: don't show ToC for each part on PDF output ...

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The configuration of the pipeline and entities directly affects the inputs required to each entity for the partition algorithm. Thus it makes sense to involve those entities in the decision making process. Extend the entity ops API to provide an optional .partition() operation. This allows entities that affect the partition window to adapt the window based on their configuration. Entities implementing this operation must update the window parameter in place, which will then be passed up the pipeline. This creates a process whereby each entity describes what is required to satisfy the required output to its predecessor in the pipeline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we develop the partition algorithm, we need to store more information per partition to describe the phase and other parameters. To keep this data together, further abstract the existing v4l2_rect into a partition specific structure. As partitions only have horizontal coordinates, store the left and width values only. When generating the partition windows, operate directly on the partition struct rather than copying and duplicating the processed data Signed-off-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
