Merge tag 'media/v4.20-6' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"First set of media patches contains:
- Three new platform drivers: aspeed-video seco-sed and sun5i-csi;
- One new sensor driver: imx214;
- Support for Xbox DVD Movie Playback kit remote controller;
- Removal of the legacy friio driver. The functionalities were ported
to another driver, already merged;
- New staging driver: Rockchip VPU;
- Added license text or SPDX tags to all media documentation files;
- Usual set of cleanup, fixes and enhancements"
