-
- - vdda-phy-supply: Phandle to a regulator supply to PHY core block.
- - vdda-pll-supply: Phandle to 1.8V regulator supply to PHY refclk pll block.
-
-Optional properties:
- - vddp-ref-clk-supply: Phandle to a regulator supply to any specific refclk
- pll block.
-
-Required nodes:
- - Each device node of QMP phy is required to have as many child nodes as
- the number of lanes the PHY has.
-
-Required properties for child nodes of PCIe PHYs (one child per lane):
- - reg: list of offset and length pairs of register sets for PHY blocks -
- tx, rx, pcs, and pcs_misc (optional).
- - #phy-cells: must be 0
-
-Required properties for a single "lanes" child node of non-PCIe PHYs:
- - reg: list of offset and length pairs of register sets for PHY blocks
- For 1-lane devices:
- tx, rx, pcs, and (optionally) pcs_misc
- For 2-lane devices:
- tx0, rx0, pcs, tx1, rx1, and (optionally) pcs_misc
- - #phy-cells: must be 0
-
-Required properties for child node of PCIe and USB3 qmp phys:
- - clocks: a list of phandles and clock-specifier pairs,
- one for each entry in clock-names.
- - clock-names: Must contain following:
- "pipe<lane-number>" for pipe clock specific to each lane.
- - clock-output-names: Name of the PHY clock that will be the parent for
- the above pipe clock.
- For "qcom,ipq8074-qmp-pcie-phy":
- - "pcie20_phy0_pipe_clk" Pipe Clock parent
- (or)
- "pcie20_phy1_pipe_clk"
- - #clock-cells: must be 0
- - Phy pll outputs pipe clocks for pipe based PHYs. These clocks are then
- gate-controlled by the gcc.
-
-Required properties for child node of PHYs with lane reset, AKA:
- "qcom,msm8996-qmp-pcie-phy"
- - resets: a list of phandles and reset controller specifier pairs,
- one for each entry in reset-names.
- - reset-names: Must contain following:
- "lane<lane-number>" for reset specific to each lane.
