Merge tag 'media/v4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: "Brazil's Independence Day pull request :-) This is one of the biggest media pull requests, with 625 patches affecting almost all parts of media (RC, DVB, V4L2, CEC, docs). 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 ...
