[PATCH v6 00/16] Add Rockchip RK3399 USB3.0 Host support

[PATCH v6 00/16] Add Rockchip RK3399 USB3.0 Host support

[Frank Wang]

This series add quirks for DWC3 and add Rockchip RK3399 USB3.0 host support.

The function has been tested pass on rk3399-evb and roc-rk3399-pc board.

For V6 update:
 - Use [PATCH v6 04/16] instead of [PATCH v5 05/16] to fix that the current
   Generic PHY subsystem is unable to find PHY if the PHY node is not part of
   the root structure.
 - Add 'Reviewed-by' tag for all patches except [PATCH v6 04/16].

For V5 update:
 - Fix dwc3-generic driver followed Marek's comments for [PATCH v4 12/16].
 - Add 'Reviewed-by' and 'Tested-by' tag for [PATCH v4 07/16] and [PATCH v4 08/16].

For V4 update:
 - Collect Jagan's all fixed patches [1].
 - Amend specific u-boot changes from dts to dtsi for [PATCH v3 6/7].

For V3 update:
 - Fix compile error for [PATCH v2 1/9].
 - Use Jagan's Type-C driver instead of [PATCH v2 5/9].
 - Cleanup dts changes for [PATCH v2 7/9].
 - Cleanup config changes for [PATCH v2 8/9] and [PATCH v2 9/9].

For V2 update:
 - Amend type-c driver followed Jagan's comments for [PATCH 5/8].
 - Fix dts commit for [PATCH 7/8].
 - Split RK3399 default config for [PATCH 8/8].
 - Add 'Reviewed-by' tag for [PATCH 1/8], [PATCH 2/8] and [PATCH 3/8].

[PATCH v6 02/16] clk: rk3399: Set empty for TCPHY assigned-clocks

[Frank Wang]

From: Jagan Teki <jagan@amarulasolutions.com>

Due to v5.7-rc1 sync the SD controller nodes in rk3399.dtsi
have SCLK_UPHY0_TCPDCORE, SCLK_UPHY1_TCPDCORE assigned-clocks
which are usually required for Linux and don't require to
handle them in U-Boot.

  assigned-clocks = <&cru SCLK_UPHY0_TCPDCORE>;
  assigned-clocks = <&cru SCLK_UPHY1_TCPDCORE>;

So, mark them as empty in clock otherwise device probe on
those typec phy driver would fail.

[Frank Wang]

There are some sub-nodes under the grf DT, so add bind callback
function in rk3399 syscon driver to scan them recursively.

[PATCH v6 05/16] phy: rockchip: Add Rockchip USB2PHY driver

[Frank Wang]

From: Jagan Teki <jagan@amarulasolutions.com>

Add Rockchip USB2PHY driver with initial support.

This will help to use it for EHCI controller in host
mode, and USB 3.0 controller in otg mode.

More functionality like charge, vbus detection will
add it in future changes.

[PATCH v6 06/16] phy: rockchip: Add Rockchip USB TypeC PHY driver

[Frank Wang]

From: Jagan Teki <jagan@amarulasolutions.com>

Add USB TYPEC PHY driver for rockchip platform.

Referenced from Linux TypeC PHY driver, currently
supporting usb3-port and dp-port need to add it
in the future.

[PATCH v6 09/16] usb: dwc3: Add disable u2mac linestate check quirk

[Frank Wang]

From: Jagan Teki <jagan@amarulasolutions.com>

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.

Reference from below Linux commit,

commit <65db7a0c9816> ("usb: dwc3: add disable u2mac linestate
check quirk")

[PATCH v6 10/16] usb: dwc3: Enable AutoRetry feature in the controller

[Frank Wang]

From: Jagan Teki <jagan@amarulasolutions.com>

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.

Reference from below Linux commit,

commit <b138e23d3dff> ("usb: dwc3: core: Enable AutoRetry feature
in the controller")

[PATCH v6 12/16] usb: dwc3: add make compatible for rockchip platform

[Frank Wang]

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.

[PATCH v6 13/16] driver: usb: drop legacy rockchip xhci driver

[Frank Wang]

We have changed to use dwc3 generic driver for usb3.0 host, so the
legacy Rockchip's xHCI driver is not needed, and drop it.

this needs to be adapted for
commit f7ae49fc4f36 ("common: Drop log.h from common header")
which added a

Whatever SuperSpeed device I plug into USB-C port it gets recognized as
HighSpeed only.

"cannot reset port 1!?" message appears on almost (3/4) each 'usb start'
and each 'usb reset' command.

Also checked one of those usb-c 2 usb-a/hdmi/usb-c-charge dongles and
Sandisk was recognized as HighSpeed.
