- 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 344/454] drm/vc4: Set premultiplied for alpha formats
+
+commit 05202c241f1476d8e2b30bb2699f6780962972e8 upstream.
+
+Alpha formats in DRM are assumed to be premultiplied, so we should be
+setting the PREMULT bit in the plane configuration for HVS.
+
+Changes from v1:
+ - Use correct has_alpha
