- 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 141/454] config: Add PINCTRL_MCP23S08
+
+As of Linux 4.12, the mcp23s08 driver moved from drivers/gpio to
+drivers/pinctrl. At the same time, the Kconfig symbols changed
+from CONFIG_GPIO_MCP23S08 to CONFIG_PINCTRL_MCP23S08, effectively
+removing the MCP23S17 from the downstream defconfigs. Restore
+support by adding CONFIG_PINCTRL_MCP23S08.
