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 131/454] drm/vc4: Fix pitch setup for T-format scanout.
|
|
|
|
The documentation said to use src_w here, and I didn't consider that
|
|
we actually needed to be using pitch somewhere in our setup. Fixes
|
|
scanout on my DSI panel when X11 does initial setup with 1920x1080
|
|
HDMI and 800x480 DSI both at 0,0 of the same framebuffer.
