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 {

		device_type = "memory";

		reg = <0x00000000 0x8000000>;

	};



	soc {

		#address-cells = <1>;

		#size-cells = <1>;

		ranges;

		compatible = "simple-bus";

		interrupt-parent = <&intcon>;



		syscon: syscon@40000000 {

			compatible = "cortina,gemini-syscon", "syscon";

			reg = <0x40000000 0x1000>;

			#clock-cells = <1>;

			#reset-cells = <1>;

		};



		uart0: serial@42000000 {

			compatible = "ns16550a";

			reg = <0x42000000 0x100>;

			resets = <&syscon GEMINI_RESET_UART>;

			clocks = <&syscon GEMINI_CLK_UART>;

			interrupts = <18 IRQ_TYPE_LEVEL_HIGH>;

			reg-shift = <2>;

		};



		timer@43000000 {

			compatible = "cortina,gemini-timer";

			reg = <0x43000000 0x1000>;

			interrupt-parent = <&intcon>;

			interrupts = <14 IRQ_TYPE_EDGE_FALLING>, /* Timer 1 */

				     <15 IRQ_TYPE_EDGE_FALLING>, /* Timer 2 */

				     <16 IRQ_TYPE_EDGE_FALLING>; /* Timer 3 */

			resets = <&syscon GEMINI_RESET_TIMER>;

			/* APB clock or RTC clock */

			clocks = <&syscon GEMINI_CLK_APB>,

				 <&syscon GEMINI_CLK_RTC>;

			clock-names = "PCLK", "EXTCLK";

			syscon = <&syscon>;

		};



		intcon: interrupt-controller@48000000 {

			compatible = "cortina,gemini-interrupt-controller";

			reg = <0x48000000 0x1000>;

			resets = <&syscon GEMINI_RESET_INTCON0>;

			interrupt-controller;

			#interrupt-cells = <2>;

		};

	};

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>;
