  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 336/454] media: adv7180: Nasty hack to allow input selection.
+
+Whilst the adv7180 driver support s_routing, nothing else
+does, and there is a missing lump of framework code to
+define the mapping from connectors on a board to the inputs
+they represent on the ADV7180.
+
+Add a nasty hack to take a module parameter that is passed in
+to s_routing on any call to G_STD, or S_STD (or subdev
+g_input_status call).
