- 950-0421-HID-hid-bigbenff-driver-for-BigBen-Interactive-PS3OF.patch
- 950-0453-Add-hid-bigbenff-to-list-of-have_special_driver-for-.patch

Make I2C built-in instead of modular as in upstream defconfig; also the
easiest way to get MFD_ARIZONA enabled, which is required by
kmod-sound-soc-rpi-cirrus.
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

+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.
+
