|
|
|
PROPERTIES |
|
|
|
- compatible: |
|
Usage: required |
|
Value type: <string> |
|
Definition: Should contain "qcom,usb-hs-phy" and more specifically one of the |
|
following: |
|
|
|
"qcom,usb-hs-phy-apq8064" |
|
"qcom,usb-hs-phy-msm8916" |
|
"qcom,usb-hs-phy-msm8974" |
|
|
|
- #phy-cells: |
|
Usage: required |
|
Value type: <u32> |
|
Definition: Should contain 0 |
|
|
|
- clocks: |
|
Usage: required |
|
Value type: <prop-encoded-array> |
|
Definition: Should contain clock specifier for the reference and sleep |
|
clocks |
|
|
|
- clock-names: |
|
Usage: required |
|
Value type: <stringlist> |
|
Definition: Should contain "ref" and "sleep" for the reference and sleep |
|
clocks respectively |
|
|
|
- resets: |
|
Usage: required |
|
Value type: <prop-encoded-array> |
|
Definition: Should contain the phy and POR resets |
|
|
|
- reset-names: |
|
Usage: required |
|
Value type: <stringlist> |
|
Definition: Should contain "phy" and "por" for the phy and POR resets |
|
respectively |
|
|
|
- v3p3-supply: |
|
Usage: required |
|
Value type: <phandle> |
|
Definition: Should contain a reference to the 3.3V supply |
|
|
|
- v1p8-supply: |
|
Usage: required |
|
Value type: <phandle> |
|
Definition: Should contain a reference to the 1.8V supply |
|
|
|
- extcon: |
|
Usage: optional |
|
Value type: <prop-encoded-array> |
|
Definition: Should contain the vbus extcon |
|
|
|
- qcom,init-seq: |
|
Usage: optional |
|
Value type: <u8 array> |
|
Definition: Should contain a sequence of ULPI address and value pairs to |
|
program into the ULPI_EXT_VENDOR_SPECIFIC area. This is related |
|
to Device Mode Eye Diagram test. The addresses are offsets |
|
from the ULPI_EXT_VENDOR_SPECIFIC address, for example, |
|
<0x1 0x53> would mean "write the value 0x53 to address 0x81". |
