Merge tag 'arm-soc/for-5.20/devicetree' of https://github.com/Broadcom/stblinux into arm/dt

This pull request contains Broadcom ARM-based SoCs Device Tree updates
for 5.20, please pull the following:

- Stefan drops the unnecessary "#address-cells" and "#size-cells"
properties from the DPI node of BCM283x

- Anand documents and adds support for the 63178 and 6858 SoCs

- William migrates the 63138 platform over to ARCH_BCMBCA and ensures
that it is documented within the BCMBCA Device Tree binding documents.
He updates the 47622 DTS to remove unnecessary PSCI properties, fix
the GIC nodes and some minor cosmetic changes. He finally adds support
for the 63158, 4912, 6846, 6855, 6756, 63146, 6856, 63148, 6813, 6318
SoCs.

- Peter, Nicolas and Stefan adds the necessary Device Tree nodes to the
BCM2711 (Raspberry Pi 4) DTS to enable the use of the V3D GPU on these
platforms.

- Christian adds support for the BCM53015 based Cisco Meraki MR26
Wi-Fi access point.

- Krzysztof updates the Broadcom platforms DTS to add a missing
whitespace between the property name and its value.

-BCM2835 PM (Power domains, watchdog)
-
-The PM block controls power domains and some reset lines, and includes
-a watchdog timer.  This binding supersedes the brcm,bcm2835-pm-wdt
-binding which covered some of PM's register range and functionality.
-
-Required properties:
-
-- compatible:		Should be "brcm,bcm2835-pm"
-- reg:			Specifies base physical address and size of the two
-			  register ranges ("PM" and "ASYNC_BRIDGE" in that
-			  order)
-- clocks:		a) v3d: The V3D clock from CPRMAN
-			b) peri_image: The PERI_IMAGE clock from CPRMAN
-			c) h264: The H264 clock from CPRMAN
-			d) isp: The ISP clock from CPRMAN
-- #reset-cells: 	Should be 1.  This property follows the reset controller
-			  bindings[1].
-- #power-domain-cells:	Should be 1.  This property follows the power domain
-			  bindings[2].
-
-Optional properties:
-
-- timeout-sec:		Contains the watchdog timeout in seconds
-- system-power-controller: Whether the watchdog is controlling the
-    system power.  This node follows the power controller bindings[3].
