Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx. Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y) Runtime-tested: bcm2708, bcm2710 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

Subject: [PATCH 113/454] drm/vc4: Fix sending of page flip completion events
|
|
in FKMS mode.
|
|
|
|
In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
|
|
CRTC's atomic flush handler that moved the completion event from the
|
|
proposed atomic state change to the CRTC's current state. That meant
|
|
that when full screen pageflipping happened (glxgears -fullscreen in
|
|
X, compton, por weston), the app would end up blocked firever waiting
|
|
to draw its next frame.
