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 285/454] Reduce log spam when mailbox call not implemented
|
|
|
|
This changes the logging message when a mailbox call
|
|
fails to the dev_dbg level. In addition, it fixes the
|
|
low voltage detection logging code so that if the
|
|
mailbox call doies fails, it logs at error level
|
|
and flags so the call is no longer attempted.
