7 title: Cadence Torrent SD0801 PHY
10 This binding describes the Cadence SD0801 PHY (also known as Torrent PHY)
11 hardware included with the Cadence MHDP DisplayPort controller. Torrent
12 PHY also supports multilink multiprotocol combinations including protocols
13 such as PCIe, USB, SGMII, QSGMII etc.

39 PHY input reference clocks - refclk (for PLL0) & pll1_refclk (for PLL1).
40 pll1_refclk is optional and used for multi-protocol configurations requiring
41 separate reference clock for each protocol.
42 Same refclk is used for both PLL0 and PLL1 if no separate pll1_refclk is used.
43 Optional parent clock (phy_en_refclk) to enable a reference clock output feature
44 on some platforms to output either derived or received reference clock.
50 - enum: [ pll1_refclk, phy_en_refclk ]
55 - description: Offset of the Torrent PHY configuration registers.
56 - description: Offset of the DPTX PHY configuration registers.
67 - description: Torrent PHY reset.
68 - description: Torrent APB reset. This is optional.
73 - const: torrent_reset
80 Each group of PHY lanes with a single master lane should be represented as a sub-node.
84 The master lane number. This is the lowest numbered lane in the lane group.
92 Contains list of resets, one per lane, to get all the link lanes out of reset.
99 Specifies the type of PHY for which the group of PHY lanes is used.
100 Refer include/dt-bindings/phy/phy.h. Constants from the header should be used.
101 $ref: /schemas/types.yaml#/definitions/uint32
108 $ref: /schemas/types.yaml#/definitions/uint32
114 Specifies the Spread Spectrum Clocking mode used. It can be NO_SSC,
115 EXTERNAL_SSC or INTERNAL_SSC.
116 Refer include/dt-bindings/phy/phy-cadence.h for the constants to be used.
117 $ref: /schemas/types.yaml#/definitions/uint32
123 Maximum DisplayPort link bit rate to use, in Mbps
