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 222/454] overlays: i2c-gpio: Support for multiple instances
|
|
|
|
Add a 'bus' parameter that, if set to a unique, non-zero
|
|
value, allows multiple i2c-gpio instances to coexist. The chosen
|
|
value doesn't determine the /dev/i2c-* value, but starting with
|
|
1 or 2 and counting upwards seems sensible. N.B. The bus parameter
|
|
has a default value of zero, so one instance doesn't need to specify
|
|
a value.
