1 | synopsys DWC3 CORE |
2 | ||
3 | DWC3- USB3 CONTROLLER | |
4 | ||
5 | Required properties: | |
22a5aa17 | 6 | - compatible: must be "snps,dwc3" |
5088b6f5 KVA |
7 | - reg : Address and length of the register set for the device |
8 | - interrupts: Interrupts used by the dwc3 controller. | |
57303488 KVA |
9 | |
10 | Optional properties: | |
23381db7 KG |
11 | - usb-phy : array of phandle for the PHY device. The first element |
12 | in the array is expected to be a handle to the USB2/HS PHY and | |
13 | the second element is expected to be a handle to the USB3/SS PHY | |
57303488 KVA |
14 | - phys: from the *Generic PHY* bindings |
15 | - phy-names: from the *Generic PHY* bindings | |
5088b6f5 | 16 | - tx-fifo-resize: determines if the FIFO *has* to be reallocated. |
eac68e8f | 17 | - snps,usb3_lpm_capable: determines if platform is USB3 LPM capable |
3b81221a HR |
18 | - snps,disable_scramble_quirk: true when SW should disable data scrambling. |
19 | Only really useful for FPGA builds. | |
80caf7d2 HR |
20 | - snps,has-lpm-erratum: true when DWC3 was configured with LPM Erratum enabled |
21 | - snps,lpm-nyet-threshold: LPM NYET threshold | |
9a5b2f31 | 22 | - snps,u2exit_lfps_quirk: set if we want to enable u2exit lfps quirk |
b5a65c40 | 23 | - snps,u2ss_inp3_quirk: set if we enable P3 OK for U2/SS Inactive quirk |
df31f5b3 HR |
24 | - snps,req_p1p2p3_quirk: when set, the core will always request for |
25 | P1/P2/P3 transition sequence. | |
a2a1d0f5 HR |
26 | - snps,del_p1p2p3_quirk: when set core will delay P1/P2/P3 until a certain |
27 | amount of 8B10B errors occur. | |
41c06ffd HR |
28 | - snps,del_phy_power_chg_quirk: when set core will delay PHY power change |
29 | from P0 to P1/P2/P3. | |
fb67afca | 30 | - snps,lfps_filter_quirk: when set core will filter LFPS reception. |
14f4ac53 HR |
31 | - snps,rx_detect_poll_quirk: when set core will disable a 400us delay to start |
32 | Polling LFPS after RX.Detect. | |
6b6a0c9a HR |
33 | - snps,tx_de_emphasis_quirk: when set core will set Tx de-emphasis value. |
34 | - snps,tx_de_emphasis: the value driven to the PHY is controlled by the | |
35 | LTSSM during USB3 Compliance mode. | |
59acfa20 | 36 | - snps,dis_u3_susphy_quirk: when set core will disable USB3 suspend phy. |
0effe0a3 | 37 | - snps,dis_u2_susphy_quirk: when set core will disable USB2 suspend phy. |
460d098c HR |
38 | - snps,is-utmi-l1-suspend: true when DWC3 asserts output signal |
39 | utmi_l1_suspend_n, false when asserts utmi_sleep_n | |
40 | - snps,hird-threshold: HIRD threshold | |
3e10a2ce HK |
41 | - snps,hsphy_interface: High-Speed PHY interface selection between "utmi" for |
42 | UTMI+ and "ulpi" for ULPI when the DWC_USB3_HSPHY_INTERFACE has value 3. | |
3737c544 NB |
43 | - snps,quirk-frame-length-adjustment: Value for GFLADJ_30MHZ field of GFLADJ |
44 | register for post-silicon frame length adjustment when the | |
45 | fladj_30mhz_sdbnd signal is invalid or incorrect. | |
