- 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 205/454] dwc_otg: Fix a regression when dequeueing isochronous
+ transfers
+
+In 282bed95 (dwc_otg: make nak_holdoff work as intended with empty queues)
+the dequeue mechanism was changed to leave FIQ-enabled transfers to run
+to completion - to avoid leaving hub TT buffers with stale packets lying
+around.
+
+This broke FIQ-accelerated isochronous transfers, as this then meant that
+dozens of transfers were performed after the dequeue function returned.
+
+Restore the state machine fence for isochronous transfers.
