  MEDIA_SUBDRV_AUTOSELECT
- 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 223/454] i2c-gpio: Also set bus numbers from reg property
+
+I2C busses can be assigned specific bus numbers using aliases in
+Device Tree - string properties where the name is the alias and the
+value is the path to the node. The current DT parameter mechanism
+does not allow property names to be derived from a parameter value
+in any way, so it isn't possible to generate unique or matching
+aliases for nodes from an overlay that can generate multiple
+instances, e.g. i2c-gpio.
+
+Work around this limitation (at least temporarily) by allowing
+the i2c adapter number to be initialised from the "reg" property
+if present.
