7 title: Common PHY and network PCS transmit amplitude property binding
10 Binding describing the peak-to-peak transmit amplitude for common PHYs
14 - Marek BehĂșn <kabel@kernel.org>
19 Transmit amplitude voltages in microvolts, peak-to-peak. If this property
20 contains multiple values for various PHY modes, the
21 'tx-p2p-microvolt-names' property must be provided and contain
22 corresponding mode names.
24 tx-p2p-microvolt-names:
26 Names of the modes corresponding to voltages in the 'tx-p2p-microvolt'
27 property. Required only if multiple voltages are provided.
29 If a value of 'default' is provided, the system should use it for any PHY
30 mode that is otherwise not defined here. If 'default' is not provided, the
31 system should use manufacturer default value.
93 tx-p2p-microvolt-names: [ tx-p2p-microvolt ]
95 additionalProperties: true
101 tx-p2p-microvolt = <915000>, <1100000>, <1200000>;
102 tx-p2p-microvolt-names = "2500base-x", "usb-hs", "usb-ss";
