1 Qualcomm's USB HS PHY
2
3 PROPERTIES
4
5 - compatible:
6 Usage: required
7 Value type: <string>
8 Definition: Should contain "qcom,usb-hs-phy" and more specifically one of the
9 following:
10
11 "qcom,usb-hs-phy-apq8064"
12 "qcom,usb-hs-phy-msm8916"
13 "qcom,usb-hs-phy-msm8974"
14
15 - #phy-cells:
16 Usage: required
17 Value type: <u32>
18 Definition: Should contain 0
19
20 - clocks:
21 Usage: required
22 Value type: <prop-encoded-array>
23 Definition: Should contain clock specifier for the reference and sleep
24 clocks
25
26 - clock-names:
27 Usage: required
28 Value type: <stringlist>
29 Definition: Should contain "ref" and "sleep" for the reference and sleep
30 clocks respectively
31
32 - resets:
33 Usage: required
34 Value type: <prop-encoded-array>
35 Definition: Should contain the phy and POR resets
36
37 - reset-names:
38 Usage: required
39 Value type: <stringlist>
40 Definition: Should contain "phy" and "por" for the phy and POR resets
41 respectively
42
43 - v3p3-supply:
44 Usage: required
45 Value type: <phandle>
46 Definition: Should contain a reference to the 3.3V supply
47
48 - v1p8-supply:
49 Usage: required
50 Value type: <phandle>
51 Definition: Should contain a reference to the 1.8V supply
52
53 - extcon:
54 Usage: optional
55 Value type: <prop-encoded-array>
56 Definition: Should contain the vbus extcon
57
58 - qcom,init-seq:
59 Usage: optional
60 Value type: <u8 array>
61 Definition: Should contain a sequence of ULPI address and value pairs to
62 program into the ULPI_EXT_VENDOR_SPECIFIC area. This is related
63 to Device Mode Eye Diagram test. The addresses are offsets
64 from the ULPI_EXT_VENDOR_SPECIFIC address, for example,
65 <0x1 0x53> would mean "write the value 0x53 to address 0x81".
