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 434/454] mmc/bcm2835: Recover from MMC_SEND_EXT_CSD
|
|
|
|
If the user issues an "mmc extcsd read", the SD controller receives
|
|
what it thinks is a SEND_IF_COND command with an unexpected data block.
|
|
The resulting operations leave the FSM stuck in READWAIT, a state which
|
|
persists until the MMC framework resets the controller, by which point
|
|
the root filesystem is likely to have been unmounted.
|
|
|
|
A less heavyweight solution is to detect the condition and nudge the
|
|
FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
|
|
|
|
N.B. This workaround was essentially discovered by accident and without
|
|
a full understanding the inner workings of the controller, so it is
|
|
fortunate that the "fix" only modifies error paths.
|
|
|
