Conversion of Qualcomm USB HS phy documentation to yaml.
Signed-off-by: David Heidelberg <[email protected]>
---
v2:
- changed uint8 array to matrix
- improved clock-names check
- move reset-names items, adjust DTS files later
- added clocks and resets min and maxItems
- if'ed resets, since apq8064 doesn't have phy reset

- Definition: Should contain "qcom,usb-hs-phy" and more specifically one of the

-
- "qcom,usb-hs-phy-apq8064"
- "qcom,usb-hs-phy-msm8916"

- 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

-

- 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".
