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 324/454] ov5647: Add support for non-continuous clock mode
|
|
|
|
The driver was only supporting continuous clock mode
|
|
although this was not stated anywhere.
|
|
Non-continuous clock saves a small amount of power and
|
|
on some SoCs is easier to interface with.
