 - Support for DMA parent bus which are not a parent node

 - Clang -Wunsequenced fix

 - Remove some unnecessary prints on memory alloc failures

 - Various printk msg and comment fixes

 - Update DT schema tools repository location

 - Convert simple-framebuffer binding to DT schema

 - Bindings for isl68137 and ir38064 trivial devices

 - New documentation on binding do's and don't's for binding writers to
   ignore

Allwinner Memory Bus (MBUS) controller



The MBUS controller drives the MBUS that other devices in the SoC will

use to perform DMA. It also has a register interface that allows to

monitor and control the bandwidth and priorities for masters on that

bus.



Required properties:

 - compatible: Must be one of:

	- allwinner,sun5i-a13-mbus

 - reg: Offset and length of the register set for the controller

 - clocks: phandle to the clock driving the controller

 - dma-ranges: See section 2.3.9 of the DeviceTree Specification

 - #interconnect-cells: Must be one, with the argument being the MBUS

   port ID



Each device having to perform their DMA through the MBUS must have the

interconnects and interconnect-names properties set to the MBUS

controller and with "dma-mem" as the interconnect name.



Example:



mbus: dram-controller@1c01000 {

	compatible = "allwinner,sun5i-a13-mbus";

	reg = <0x01c01000 0x1000>;

	clocks = <&ccu CLK_MBUS>;

	dma-ranges = <0x00000000 0x40000000 0x20000000>;

	#interconnect-cells = <1>;

};



fe0: display-frontend@1e00000 {

	compatible = "allwinner,sun5i-a13-display-frontend";

	...

	interconnects = <&mbus 19>;

	interconnect-names = "dma-mem";

};

Meson specific Simple Framebuffer bindings



This binding documents meson specific extensions to the simple-framebuffer

bindings. The meson simplefb u-boot code relies on the devicetree containing

pre-populated simplefb nodes.



These extensions are intended so that u-boot can select the right node based

on which pipeline is being used. As such they are solely intended for

firmware / bootloader use, and the OS should ignore them.



Required properties:

- compatible: "amlogic,simple-framebuffer", "simple-framebuffer"

- amlogic,pipeline, one of:

  "vpu-cvbs"

  "vpu-hdmi"



Example:



chosen {

	#address-cells = <2>;

	#size-cells = <2>;

	ranges;



	simplefb_hdmi: framebuffer-hdmi {

		compatible = "amlogic,simple-framebuffer",

			     "simple-framebuffer";

		amlogic,pipeline = "vpu-hdmi";

		clocks = <&clkc CLKID_HDMI_PCLK>,

			 <&clkc CLKID_CLK81>,

			 <&clkc CLKID_GCLK_VENCI_INT0>;

		power-domains = <&pwrc_vpu>;
