- phys: from the *Generic PHY* bindings
- phy-names: from the *Generic PHY* bindings
- tx-fifo-resize: determines if the FIFO *has* to be reallocated.
+ - snps,disable_scramble_quirk: true when SW should disable data scrambling.

+ - snps,u2exit_lfps_quirk: set if we want to enable u2exit lfps quirk
+ - snps,u2ss_inp3_quirk: set if we enable P3 OK for U2/SS Inactive quirk
+ - snps,req_p1p2p3_quirk: when set, the core will always request for
+ P1/P2/P3 transition sequence.
+ - snps,del_p1p2p3_quirk: when set core will delay P1/P2/P3 until a certain

+ - snps,del_phy_power_chg_quirk: when set core will delay PHY power change
+ from P0 to P1/P2/P3.
+ - snps,lfps_filter_quirk: when set core will filter LFPS reception.
+ - snps,rx_detect_poll_quirk: when set core will disable a 400us delay to start
+ Polling LFPS after RX.Detect.
+ - snps,tx_de_emphasis_quirk: when set core will set Tx de-emphasis value.
+ - snps,tx_de_emphasis: the value driven to the PHY is controlled by the

+ - snps,hird-threshold: HIRD threshold
This is usually a subnode to DWC3 glue to which it is connected.
