-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>;
