-Cortina systems Gemini platforms
-
-The Gemini SoC is the project name for an ARMv4 FA525-based SoC originally
-produced by Storlink Semiconductor around 2005. The company was renamed
-later renamed Storm Semiconductor. The chip product name is Storlink SL3516.
-It was derived from earlier products from Storm named SL3316 (Centroid) and
-SL3512 (Bulverde).
-
-Storm Semiconductor was acquired by Cortina Systems in 2008 and the SoC was
-produced and used for NAS and similar usecases. In 2014 Cortina Systems was
-in turn acquired by Inphi, who seem to have discontinued this product family.
-
-Many of the IP blocks used in the SoC comes from Faraday Technology.
-
-Required properties (in root node):
-	compatible = "cortina,gemini";
-
-Required nodes:
-
-- soc: the SoC should be represented by a simple bus encompassing all the
-  onchip devices, this is referred to as the soc bus node.
-
-- syscon: the soc bus node must have a system controller node pointing to the
-  global control registers, with the compatible string
-  "cortina,gemini-syscon", "syscon";
-
-  Required properties on the syscon:
-  - reg: syscon register location and size.
-  - #clock-cells: should be set to <1> - the system controller is also a
-                  clock provider.
-  - #reset-cells: should be set to <1> - the system controller is also a
-                  reset line provider.
-
-  The clock sources have shorthand defines in the include file:
-  <dt-bindings/clock/cortina,gemini-clock.h>
-
-  The reset lines have shorthand defines in the include file:
-  <dt-bindings/reset/cortina,gemini-reset.h>
-
-- timer: the soc bus node must have a timer node pointing to the SoC timer
-  block, with the compatible string "cortina,gemini-timer"
-  See: clocksource/cortina,gemini-timer.txt
-
-- interrupt-controller: the sob bus node must have an interrupt controller
-  node pointing to the SoC interrupt controller block, with the compatible
-  string "cortina,gemini-interrupt-controller"
-  See interrupt-controller/cortina,gemini-interrupt-controller.txt
-
-Example:
-
-/ {
-	model = "Foo Gemini Machine";
-	compatible = "cortina,gemini";
-	#address-cells = <1>;
-	#size-cells = <1>;
-
-	memory {

-Mediatek mmsys controller
-============================
-
-The Mediatek mmsys system controller provides clock control, routing control,
-and miscellaneous control in mmsys partition.
-
-Required Properties:
-
-- compatible: Should be one of:
-	- "mediatek,mt2701-mmsys", "syscon"
-	- "mediatek,mt2712-mmsys", "syscon"
-	- "mediatek,mt6765-mmsys", "syscon"
-	- "mediatek,mt6779-mmsys", "syscon"
-	- "mediatek,mt6797-mmsys", "syscon"
-	- "mediatek,mt7623-mmsys", "mediatek,mt2701-mmsys", "syscon"
-	- "mediatek,mt8167-mmsys", "syscon"
-	- "mediatek,mt8173-mmsys", "syscon"
-	- "mediatek,mt8183-mmsys", "syscon"
-- #clock-cells: Must be 1
-
-For the clock control, the mmsys controller uses the common clk binding from
-Documentation/devicetree/bindings/clock/clock-bindings.txt
-The available clocks are defined in dt-bindings/clock/mt*-clk.h.
-
-Example:
-
-mmsys: syscon@14000000 {
-	compatible = "mediatek,mt8173-mmsys", "syscon";
-	reg = <0 0x14000000 0 0x1000>;
-	#clock-cells = <1>;
