- Revert "mm: alloc_contig: re-allow CMA to compact FS pages"
- Revert "Revert "mm: alloc_contig: re-allow CMA to compact FS pages""
- cxd2880: CXD2880_SPI_DRV should select DVB_CXD2880 with
  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

++Broadcom BCM283x Camera Interface (Unicam)
++------------------------------------------
++
++The Unicam block on BCM283x SoCs is the receiver for either
++CSI-2 or CCP2 data from image sensors or similar devices.
++
++The main platform using this SoC is the Raspberry Pi family of boards.
++On the Pi the VideoCore firmware can also control this hardware block,
++and driving it from two different processors will cause issues.
++To avoid this, the firmware checks the device tree configuration
++during boot. If it finds device tree nodes called csi0 or csi1 then
++it will stop the firmware accessing the block, and it can then
++safely be used via the device tree binding.
++
++Required properties:
++===================
++- compatible	: must be "brcm,bcm2835-unicam".
++- reg		: physical base address and length of the register sets for the
++		  device.
++- interrupts	: should contain the IRQ line for this Unicam instance.
++- clocks	: list of clock specifiers, corresponding to entries in
++		  clock-names property.
++- clock-names	: must contain an "lp" entry, matching entries in the
++		  clocks property.
++
++Unicam supports a single port node. It should contain one 'port' child node
++with child 'endpoint' node. Please refer to the bindings defined in
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Within the endpoint node the "remote-endpoint" and "data-lanes" properties
++are mandatory.
++Data lane reordering is not supported so the data lanes must be in order,
++starting at 1. The number of data lanes should represent the number of
++usable lanes for the hardware block. That may be limited by either the SoC or
++how the platform presents the interface, and the lower value must be used.
++
++Lane reordering is not supported on the clock lane either, so the optional
++property "clock-lane" will implicitly be <0>.
++Similarly lane inversion is not supported, therefore "lane-polarities" will
++implicitly be <0 0 0 0 0>.
++Neither of these values will be checked.
++
++Example:
++	csi1: csi1@7e801000 {
++		compatible = "brcm,bcm2835-unicam";
++		reg = <0x7e801000 0x800>,
++		      <0x7e802004 0x4>;
++		interrupts = <2 7>;
++		clocks = <&clocks BCM2835_CLOCK_CAM1>;
++		clock-names = "lp";
++
++		port {
++			csi1_ep: endpoint {
++				remote-endpoint = <&tc358743_0>;
++				data-lanes = <1 2>;
++			};
++		};
++	};
++
++	i2c0: i2c@7e205000 {
++		tc358743: csi-hdmi-bridge@0f {
++			compatible = "toshiba,tc358743";
++			reg = <0x0f>;
++
++			clocks = <&tc358743_clk>;
++			clock-names = "refclk";
++
++			tc358743_clk: bridge-clk {
++				compatible = "fixed-clock";
++				#clock-cells = <0>;
++				clock-frequency = <27000000>;
++			};
++
++			port {
++				tc358743_0: endpoint {
++					remote-endpoint = <&csi1_ep>;
++					clock-lanes = <0>;
++					data-lanes = <1 2>;
++					clock-noncontinuous;
++					link-frequencies =
++						/bits/ 64 <297000000>;
++				};
++			};
++		};
++	};
