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 015/454] ARM: bcm2835: Set Serial number and Revision

MIME-Version: 1.0

The VideoCore bootloader passes in Serial number and
|
|
Revision number through Device Tree. Make these available to
|
|
userspace through /proc/cpuinfo.
|
|
|
|
Mainline status:
|
|
|
|
There is a commit in linux-next that standardize passing the serial
|
|
number through Device Tree (string: /serial-number):
|
|
ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo
|
|
|
|
There was an attempt to do the same with the revision number, but it
|
|
didn't get in:
|
|
[PATCH v2 1/2] arm: devtree: Set system_rev from DT revision
