  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 181/454] drm/vc4: Use .pixel_order instead of custom
+ .flip_cbcr
+
+The hardware has enums for altering the Cr and Cb order,
+so use this instead of having a flag which swaps the
+order the pointers are presented to the hardware
+(that only worked for 3 plane formats anyway).
+
+Explicitly sets .pixel_order in each case, rather than
+relying on then default XYCBCR order being a value 0.
