  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 258/454] BCM27XX_DT: Set LED modes from Device Tree
+
+The new default values for LAN7515 (LAN7800) are:
+
+  LED0 = 1 (link1000/activity)
+  LED1 = 6 (link10/link100/activity)
+
+Also add two dtparams - eth_led0 and eth_led1 - to provide user control
+over the LEDs.
