Merge tag 'arm-soc/for-5.7/devicetree' of https://github.com/Broadcom/stblinux into arm/dt 

This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 5.7, please pull the following:

- Stefan adds GPIO labels to the Raspberry Pi 4 Model B board DTS

- Nicolas moves the eMMC2 controller into its separate node in order for
  platform firmware to perform the necessary "dma-ranges" property
  patching based on the chip revision since the eMMC controller has
  different addressing constraints.

- Florian convers a whole bunch of Broadcom boards bindings from text to
  YAML.

Broadcom Kona Family CPU Enable Method

--------------------------------------

This binding defines the enable method used for starting secondary

CPUs in the following Broadcom SoCs:

  BCM11130, BCM11140, BCM11351, BCM28145, BCM28155, BCM21664



The enable method is specified by defining the following required

properties in the "cpu" device tree node:

  - enable-method = "brcm,bcm11351-cpu-method";

  - secondary-boot-reg = <...>;



The secondary-boot-reg property is a u32 value that specifies the

physical address of the register used to request the ROM holding pen

code release a secondary CPU.  The value written to the register is

formed by encoding the target CPU id into the low bits of the

physical start address it should jump to.



Example:

	cpus {

		#address-cells = <1>;

		#size-cells = <0>;



		cpu0: cpu@0 {

			device_type = "cpu";

			compatible = "arm,cortex-a9";

			reg = <0>;

		};



		cpu1: cpu@1 {

			device_type = "cpu";

			compatible = "arm,cortex-a9";

			reg = <1>;

			enable-method = "brcm,bcm11351-cpu-method";

			secondary-boot-reg = <0x3500417c>;

		};

	};
