1 SAMSUNG USB-PHY controllers
3 ** Samsung's usb 2.0 phy transceiver
5 The Samsung's usb 2.0 phy transceiver is used for controlling
6 usb 2.0 phy for s3c-hsotg as well as ehci-s5p and ohci-exynos
7 usb controllers across Samsung SOCs.
8 TODO: Adding the PHY binding with controller(s) according to the under
9 development generic PHY driver.
14 - compatible : should be "samsung,exynos4210-usb2phy"
15 - reg : base physical address of the phy registers and length of memory mapped
17 - clocks: Clock IDs array as required by the controller.
18 - clock-names: names of clock correseponding IDs clock property as requested
19 by the controller driver.
22 - compatible : should be "samsung,exynos5250-usb2phy"
23 - reg : base physical address of the phy registers and length of memory mapped
27 - #address-cells: should be '1' when usbphy node has a child node with 'reg'
29 - #size-cells: should be '1' when usbphy node has a child node with 'reg'
31 - ranges: allows valid translation between child's address space and parent's
34 - The child node 'usbphy-sys' to the node 'usbphy' is for the system controller
35 interface for usb-phy. It should provide the following information required by
36 usb-phy controller to control phy.
37 - reg : base physical address of PHY_CONTROL registers.
38 The size of this register is the total sum of size of all PHY_CONTROL
39 registers that the SoC has. For example, the size will be
40 '0x4' in case we have only one PHY_CONTROL register (e.g.
41 OTHERS register in S3C64XX or USB_PHY_CONTROL register in S5PV210)
42 and, '0x8' in case we have two PHY_CONTROL registers (e.g.
43 USBDEVICE_PHY_CONTROL and USBHOST_PHY_CONTROL registers in exynos4x).
52 compatible = "samsung,exynos4210-usb2phy";
53 reg = <0x125B0000 0x100>;
56 clocks = <&clock 2>, <&clock 305>;

61 reg = <0x10020704 0x8>;
66 ** Samsung's usb 3.0 phy transceiver
68 Starting exynso5250, Samsung's SoC have usb 3.0 phy transceiver
69 which is used for controlling usb 3.0 phy for dwc3-exynos usb 3.0
70 controllers across Samsung SOCs.
75 - compatible : should be "samsung,exynos5250-usb3phy"
76 - reg : base physical address of the phy registers and length of memory mapped
78 - clocks: Clock IDs array as required by the controller.
79 - clock-names: names of clocks correseponding to IDs in the clock property
80 as requested by the controller driver.
83 - #address-cells: should be '1' when usbphy node has a child node with 'reg'
85 - #size-cells: should be '1' when usbphy node has a child node with 'reg'
87 - ranges: allows valid translation between child's address space and parent's
90 - The child node 'usbphy-sys' to the node 'usbphy' is for the system controller
91 interface for usb-phy. It should provide the following information required by
92 usb-phy controller to control phy.
93 - reg : base physical address of PHY_CONTROL registers.
94 The size of this register is the total sum of size of all PHY_CONTROL
95 registers that the SoC has. For example, the size will be
96 '0x4' in case we have only one PHY_CONTROL register (e.g.
97 OTHERS register in S3C64XX or USB_PHY_CONTROL register in S5PV210)
98 and, '0x8' in case we have two PHY_CONTROL registers (e.g.
99 USBDEVICE_PHY_CONTROL and USBHOST_PHY_CONTROL registers in exynos4x).
