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 223/454] i2c-gpio: Also set bus numbers from reg property
|
|
|
|
I2C busses can be assigned specific bus numbers using aliases in
|
|
Device Tree - string properties where the name is the alias and the
|
|
value is the path to the node. The current DT parameter mechanism
|
|
does not allow property names to be derived from a parameter value
|
|
in any way, so it isn't possible to generate unique or matching
|
|
aliases for nodes from an overlay that can generate multiple
|
|
instances, e.g. i2c-gpio.
|
|
|
|
Work around this limitation (at least temporarily) by allowing
|
|
the i2c adapter number to be initialised from the "reg" property
|
|
if present.
