2 -----------------------
5 - compatible: Must be "cdns,sierra-phy-t0" for Sierra in Cadence platform
6 Must be "ti,sierra-phy-t0" for Sierra in TI's J721E SoC.
7 - resets: Must contain an entry for each in reset-names.
8 See ../reset/reset.txt for details.
9 - reset-names: Must include "sierra_reset" and "sierra_apb".
10 "sierra_reset" must control the reset line to the PHY.
11 "sierra_apb" must control the reset line to the APB PHY
12 interface ("sierra_apb" is optional).
13 - reg: register range for the PHY.
14 - #address-cells: Must be 1
15 - #size-cells: Must be 0
18 - clocks: Must contain an entry in clock-names.
19 See ../clocks/clock-bindings.txt for details.
20 - clock-names: Must contain "cmn_refclk_dig_div" and
21 "cmn_refclk1_dig_div" for configuring the frequency of
22 the clock to the lanes. "phy_clk" is deprecated.
23 - cdns,autoconf: A boolean property whose presence indicates that the
24 PHY registers will be configured by hardware. If not
25 present, all sub-node optional properties must be
29 Each group of PHY lanes with a single master lane should be represented as
30 a sub-node. Note that the actual configuration of each lane is determined by
31 hardware strapping, and must match the configuration specified here.
33 Sub-node required properties:
34 - #phy-cells: Generic PHY binding; must be 0.
35 - reg: The master lane number. This is the lowest numbered lane
37 - resets: Must contain one entry which controls the reset line for the
38 master lane of the sub-node.
39 See ../reset/reset.txt for details.
41 Sub-node optional properties:
42 - cdns,num-lanes: Number of lanes in this group. From 1 to 4. The
43 group is made up of consecutive lanes.
44 - cdns,phy-type: Can be PHY_TYPE_PCIE or PHY_TYPE_USB3, depending on
45 configuration of lanes.
