- 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 349/454] drm/vc4: Fix oops dereferencing DPI's connector since
+ panel_bridge.
+
+In the cleanup, I didn't notice that we needed to dereference the
+connector for the bus_format.  Fix the regression by looking up the
+first (and only) connector attached to us, and assume that its
+bus_format is what we want.  Some day it would be good to have that
+part of display_info attached to the bridge, instead.
+
+v2: Fix stray whitespace change
