| Socionext UniPhier Regulator Controller |
| |
| This describes the devicetree bindings for regulator controller implemented |
| on Socionext UniPhier SoCs. |
| |
| USB3 Controller |
| --------------- |
| |
| This regulator controls VBUS and belongs to USB3 glue layer. Before using |
| the regulator, it is necessary to control the clocks and resets to enable |
| this layer. These clocks and resets should be described in each property. |
| |
| Required properties: |
| - compatible: Should be |
| "socionext,uniphier-pro4-usb3-regulator" - for Pro4 SoC |
| "socionext,uniphier-pro5-usb3-regulator" - for Pro5 SoC |
| "socionext,uniphier-pxs2-usb3-regulator" - for PXs2 SoC |
| "socionext,uniphier-ld20-usb3-regulator" - for LD20 SoC |
| "socionext,uniphier-pxs3-usb3-regulator" - for PXs3 SoC |
| - reg: Specifies offset and length of the register set for the device. |
| - clocks: A list of phandles to the clock gate for USB3 glue layer. |
| According to the clock-names, appropriate clocks are required. |
| - clock-names: Should contain |
| "gio", "link" - for Pro4 and Pro5 SoCs |
| "link" - for others |
| - resets: A list of phandles to the reset control for USB3 glue layer. |
| According to the reset-names, appropriate resets are required. |
| - reset-names: Should contain |
| "gio", "link" - for Pro4 and Pro5 SoCs |
| "link" - for others |
| |
| See Documentation/devicetree/bindings/regulator/regulator.txt |
| for more details about the regulator properties. |

| Example: |

| usb-glue@65b00000 { |

| "simple-mfd"; |
| #address-cells = <1>; |
| #size-cells = <1>; |
| ranges = <0 0x65b00000 0x400>; |
| |
| usb_vbus0: regulators@100 { |
| compatible = "socionext,uniphier-ld20-usb3-regulator"; |
| reg = <0x100 0x10>; |
| clock-names = "link"; |
| clocks = <&sys_clk 14>; |
| reset-names = "link"; |
| resets = <&sys_rst 14>; |
