- 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 184/454] drm/vc4: Flush the caches before the render jobs, as
+ well.
+
+If the frame samples from a render target that was just written, its
+cache flush during the binning step may have occurred before the
+previous frame's RCL was completed.  Flush the texture caches again
+before starting each RCL job to make sure that the sampling of the
+previous RCL's output is correct.
+
+Fixes flickering in the top left of 3DMMES Taiji.
