usb: dwc3: add make compatible for rockchip platform

2020-05-29T23:38:50Z

RK3399 Type-C PHY is required that must hold whole USB3.0 OTG controller in resetting to hold pipe power state in P2 before initializing the PHY. This commit fixed it and added device compatible for rockchip platform. Signed-off-by: Frank Wang Signed-off-by: Jagan Teki Reviewed-by: Kever Yang

usb: dwc3: amend UTMI/UTMIW phy interface setup

2020-05-29T10:13:19Z

Let move 8/16-bit UTMI+ interface initialization into DWC3 core init that is convenient for both DM_USB and u-boot traditional process. Signed-off-by: Frank Wang Signed-off-by: Jagan Teki Reviewed-by: Kever Yang

usb: dwc3: Enable AutoRetry feature in the controller

2020-05-29T10:13:19Z

By default when core sees any transaction error (CRC or overflow) it replies with terminating retry ACK (Retry=1 and Nump == 0). Enabling this Auto Retry feature in controller will make the core send a non-terminanting ACK upon such transaction errors. That is, ACK TP with Retry=1 and Nump != 0. Doing so will give controller a chance to recover from transient error conditions.

usb: dwc3: Add disable u2mac linestate check quirk

2020-05-29T10:13:19Z

This patch adds a quirk to disable USB 2.0 MAC linestate check during HS transmit. Refer the dwc3 databook, we can use it for some special platforms if the linestate not reflect the expected line state(J) during transmission. When use this quirk, the controller implements a fixed 40-bit TxEndDelay after the packet is given on UTMI and ignores the linestate during the transmit of a token (during token-to-token and token-to-data IPGAP). On some rockchip platforms (e.g. rk3399), it requires to disable the u2mac linestate check to decrease the SSPLIT token to SETUP token inter-packet delay from 566ns to 466ns, and fix the issue that FS/LS devices not recognized if inserted through USB 3.0 HUB.

usb: dwc3: add dis_u2_freeclk_exists_quirk

2020-05-29T10:13:19Z

Add a quirk to clear the GUSB2PHYCFG.U2_FREECLK_EXISTS bit, which specifies whether the USB2.0 PHY provides a free-running PHY clock, which is active when the clock control input is active.
