- 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 015/454] ARM: bcm2835: Set Serial number and Revision
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The VideoCore bootloader passes in Serial number and
+Revision number through Device Tree. Make these available to
+userspace through /proc/cpuinfo.
+
+Mainline status:
+
+There is a commit in linux-next that standardize passing the serial
+number through Device Tree (string: /serial-number):
+ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo
+
+There was an attempt to do the same with the revision number, but it
+didn't get in:
+[PATCH v2 1/2] arm: devtree: Set system_rev from DT revision
