-Peripheral core reset in glue layer
------------------------------------
-
-Some peripheral core reset belongs to its own glue layer. Before using
-this core reset, 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-reset" - for Pro4 SoC USB3
- "socionext,uniphier-pro5-usb3-reset" - for Pro5 SoC USB3
- "socionext,uniphier-pxs2-usb3-reset" - for PXs2 SoC USB3
- "socionext,uniphier-ld20-usb3-reset" - for LD20 SoC USB3
- "socionext,uniphier-pxs3-usb3-reset" - for PXs3 SoC USB3
- "socionext,uniphier-pro4-ahci-reset" - for Pro4 SoC AHCI
- "socionext,uniphier-pxs2-ahci-reset" - for PXs2 SoC AHCI
- "socionext,uniphier-pxs3-ahci-reset" - for PXs3 SoC AHCI
-- #reset-cells: Should be 1.
-- reg: Specifies offset and length of the register set for the device.
-- clocks: A list of phandles to the clock gate for the 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 the 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
-
-Example:
-
- usb-glue@65b00000 {
- compatible = "socionext,uniphier-ld20-dwc3-glue",
- "simple-mfd";
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x65b00000 0x400>;
-
- usb_rst: reset@0 {
- compatible = "socionext,uniphier-ld20-usb3-reset";
- reg = <0x0 0x4>;
- #reset-cells = <1>;
- clock-names = "link";
- clocks = <&sys_clk 14>;
- reset-names = "link";
- resets = <&sys_rst 14>;
- };
