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 240/454] audioinjector-octo: Add continuous clock feature
|
|
|
|
By user request, add a switch to prevent the clocks being stopped when
|
|
the stream is paused, stopped or shutdown. Provide access to the switch
|
|
by adding a 'non-stop-clocks' parameter to the audioinjector-addons
|
|
overlay.
|
|
|
|
See: https://github.com/raspberrypi/linux/issues/2409
