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 167/454] mmc: bcm2835-mmc: Support underclocking
|
|
|
|
Support underclocking of the SD bus using the max-frequency DT property
|
|
(which currently has no DT parameter). The sd_overclock parameter
|
|
already provides another way to achieve the same thing which should be
|
|
equivalent in end result, but it is a bug not to support max-frequency
|
|
as well.
