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 204/454] drm/vc4: Move the DSI clock divider workaround closer
|
|
to the clock call.
|
|
|
|
We want the adjusted_mode->clock to be the actual clock we're
|
|
expecting to program, so that consumers see the right values for clock
|
|
and vrefresh.
