2019-01-21media: imx: queue subdev events to reachable video devicesSteve Longerbeam1-0/+24
In order to receive events generated by subdevices on the video capture nodes, those events need to be forwarded to the subdevice's list of reachable video capture devices. Note this will queue the event to a video device even if there is no actual _enabled_ media path from the sub-device to the video device. So a future improvement is to skip the video device if there is no enabled path to it from the sub-device. The entity->pipe pointer can't be used for this check because in imx-media a sub-device can be a member to more than one streaming pipeline at a time.

2019-01-21media: ivtv: add parameter to enable ivtvfb on x86 PAT systemsFrench, Nicholas A2-5/+34
ivtvfb was previously disabled for x86 PAT-enabled systems by commit 1bf1735b4780 ("x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled") as a workaround to abstract MTRR code away from device drivers. The driver is not easily upgradable to the PAT-aware ioremap_wc() API since the firmware hides the address ranges that should be marked write-combined from the driver. However, since a write-combined cache on the framebuffer is only a performance enhancement not a requirement for the framebuffer to function, completely disabling the driver in this configuration is not necessary. Add force_pat module parameter and a corresponding kernel configuration parameter to optionally force initialization on PAT-enabled x86 systems with a warning about the lack of write-combined caching, and document the reasons the driver cannot be easily updated to support wc caching on all systems.
