Merge tag 'phy_common_properties' of git://git.kernel.org/pub/scm/linux/kernel/git/phy/linux-phy 

Vinod Koul says:

====================
phy common properties

Introduce "rx-polarity" and "tx-polarity" device tree properties
with Kunit tests (from Vladimir Oltean).

* tag 'phy_common_properties' of git://git.kernel.org/pub/scm/linux/kernel/git/phy/linux-phy:
  phy: add phy_get_rx_polarity() and phy_get_tx_polarity()
  dt-bindings: phy-common-props: RX and TX lane polarity inversion
  dt-bindings: phy-common-props: ensure protocol-names are unique
  dt-bindings: phy-common-props: create a reusable "protocol-names" definition
  dt-bindings: phy: rename transmit-amplitude.yaml to phy-common-props.yaml
====================

  rx-polarity:

    description:

      An array of values indicating whether the differential receiver's

      polarity is inverted. Each value can be one of

      PHY_POL_NORMAL (0) which means the negative signal is decoded from the

      RXN input, and the positive signal from the RXP input;

      PHY_POL_INVERT (1) which means the negative signal is decoded from the

      RXP input, and the positive signal from the RXN input;

      PHY_POL_AUTO (2) which means the receiver performs automatic polarity

      detection and correction, which is a mandatory part of link training for

      some protocols (PCIe, USB SS).



      The values are defined in <dt-bindings/phy/phy.h>. If the property is

      absent, the default value is undefined.



      Note that the RXP and RXN inputs refer to the block that this property is

      under, and do not necessarily directly translate to external pins.



      If this property contains multiple values for various protocols, the

      'rx-polarity-names' property must be provided.
