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 187/454] drm/vc4: Fix warning about vblank interrupts before
|
|
DRM core is ready.
|
|
|
|
The SMICS interrupt fires continuously, but since it's 1/100 the rate
|
|
of the USB interrupts, we don't really need a way to turn it off. We
|
|
do need to make sure that we don't tell DRM about it until DRM has
|
|
asked for the interrupt at least once, because otherwise it will throw
|
|
a warning at boot time.
