Merge tag 'arm-soc/for-5.14/devicetree' of https://github.com/Broadcom/stblinux into arm/dt

This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 5.14, please pull the following:

- Rafal updates the BCM5301x, HR2, BCM63xx, BCM5301x, NSP and Cygnus DTS
  files to resolve a number of DT binding check warnings pertaining to
  NAND, pinmux, clocks, SPI

- Stefan provides a fix for an increase in the DWC2 controller's RX FIFO
  causing regressions on the Raspberry Pi 4B

- Mateusz adds a BCM2711 specific VEC compatible string to allow keying
  off that variant properly

- Stefan adds support for the Raspberry Pi 400 by doing some DTS/DTSI
  re-organization work and finally adding the DTS file proper

-Broadcom iProc Family Clocks
-
-This binding uses the common clock binding:
-    Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-The iProc clock controller manages clocks that are common to the iProc family.
-An SoC from the iProc family may have several PPLs, e.g., ARMPLL, GENPLL,
-LCPLL0, MIPIPLL, and etc., all derived from an onboard crystal. Each PLL
-comprises of several leaf clocks
-
-Required properties for a PLL and its leaf clocks:
-
-- compatible:
-    Should have a value of the form "brcm,<soc>-<pll>". For example, GENPLL on
-Cygnus has a compatible string of "brcm,cygnus-genpll"
-
-- #clock-cells:
-    Have a value of <1> since there are more than 1 leaf clock of a given PLL
-
-- reg:
-    Define the base and range of the I/O address space that contain the iProc
-clock control registers required for the PLL
-
-- clocks:
-    The input parent clock phandle for the PLL. For most iProc PLLs, this is an
-onboard crystal with a fixed rate
-
-- clock-output-names:
-    An ordered list of strings defining the names of the clocks
-
-Example:
-
-	osc: oscillator {
-		#clock-cells = <0>;
-		compatible = "fixed-clock";
-		clock-frequency = <25000000>;
-	};
-
-	genpll: genpll {
-		#clock-cells = <1>;
-		compatible = "brcm,cygnus-genpll";
-		reg = <0x0301d000 0x2c>, <0x0301c020 0x4>;
-		clocks = <&osc>;
-		clock-output-names = "genpll", "axi21", "250mhz", "ihost_sys",
-				     "enet_sw", "audio_125", "can";
-	};
-
-Required properties for ASIU clocks:
-
-ASIU clocks are a special case. These clocks are derived directly from the
-reference clock of the onboard crystal
-
-- compatible:
-    Should have a value of the form "brcm,<soc>-asiu-clk". For example, ASIU
-clocks for Cygnus have a compatible string of "brcm,cygnus-asiu-clk"
-
-- #clock-cells:
-    Have a value of <1> since there are more than 1 ASIU clocks
-
-- reg:
-    Define the base and range of the I/O address space that contain the iProc
-clock control registers required for ASIU clocks
-
-- clocks:
-    The input parent clock phandle for the ASIU clock, i.e., the onboard
-crystal
-
-- clock-output-names:
-    An ordered list of strings defining the names of the ASIU clocks
-
-Example:
-
-	osc: oscillator {
-		#clock-cells = <0>;
-		compatible = "fixed-clock";
-		clock-frequency = <25000000>;
-	};
-
-	asiu_clks: asiu_clks {
-		#clock-cells = <1>;
-		compatible = "brcm,cygnus-asiu-clk";
-		reg = <0x0301d048 0xc>, <0x180aa024 0x4>;
