openwrtv4/target/linux/brcm2708/patches-4.4/0118-drm-vc4-A-few-more-non-functional-changes-to-sync-to.patch
Felix Fietkau 4224b52c3a brcm2708: add linux 4.4 support 
- random-bcm2708 and spi-bcm2708 have been removed.
- sound-soc-bcm2708-i2s has been upstreamed as sound-soc-bcm2835-i2s.

Let's keep linux 4.1 for a while, since linux 4.4 appears to have some issues
with multicast traffic on RPi ethernet:

Subject: [PATCH 118/127] drm/vc4: A few more non-functional changes to sync to
upstream.
At this point all that's left is the force-enable of HDMI connector,
and using direct firmware calls to turn on V3D instead of the generic
power domain support.
