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
