of the individual ip-block.

2. remove unnecessary clocks, refer to rk3399 TRM, aclk_usb3 is the
parent of aclk_usb3otg0/1 and aclk_usb3_grf, and we will enable
aclk_usb3otg0/1 and aclk_usb3_grf, so don't need to enable aclk_usb3

phy: phy-rockchip-typec: fix rx eq training fail

When do Rx compliance test, PHY is in loopback mode, we
observed that Rx test failed with long cable, and it was
found that equalizer adaptation is not happening properly.
With rx_eq_training forced from PMA, the equalizer adaptation
working fine and Rx test can pass. The root cause is that
the Rx REE component will be turned off when control data
is being received by default PHY configuration. So we need
to unmask REE control data by setting REE control data mask
register, and with this patch, equalizer training will happen
based on the signal coming from controller only.

UPSTREAM: usb: dwc2: Avoid more calls to dwc2_core_reset()

Calls to dwc2_core_reset() are currently very slow, taking at least
150ms (possibly more).  It behooves us to take as many of these calls
out as possible.

It turns out that the calls in dwc2_fs_phy_init() and dwc2_hs_phy_init()
should (as documented in the code) only be needed if we need to do a PHY
SELECT.  That means that if we see that we can avoid the PHY SELECT then
we can avoid the reset.

This patch appears to successfully bypass two resets (one per USB
device) on rk3288-based ARM Chromebooks.

UPSTREAM: usb: dwc2: reduce dwc2 driver probe time

I found that the probe function of dwc2 driver takes much time
when kernel boot up. There are many long delays in the probe
function these take almost 1 second.

This patch trying to reduce unnecessary delay time.

In dwc2_core_reset() I see it use two at least 20ms delays to
wait AHB idle and core soft reset, but dwc2 data book said that
dwc2 core soft reset and AHB idle just need a few clocks (I think
it refers to AHB clock, and AHB clock run at 150MHz in my RK3288
board), so 20ms is too long, delay 1us for wait AHB idle and soft
reset is enough.

And in dwc2_get_hwparams() it takes 150ms to wait ForceHostMode
and ForceDeviceMode valid but in data book it said software must
wait at least 25ms before the change to take effect, so I reduce
this time to 25ms~50ms. By the way, is there any state bit show
that the force mode take effect ? Could we poll curmod bit for
figuring out if the change take effect ?

It seems that usleep_range() at boot time will pick the longest
value in the range. In dwc2_core_reset() there is a very long
delay takes 200ms, and this function run twice when probe, could
any one tell me is this delay time resonable ?

I have tried this patch in my RK3288-evb board. It works well.

UPSTREAM: usb: dwc2: Speed dwc2_get_hwparams() on some host-only ports

On some host-only DWC2 ports (like the one in rk3288) when we set
GUSBCFG_FORCEHOSTMODE in GUSBCFG and then read back, we don't see the
bit set.  Presumably that's because the port is always forced to HOST
mode so there's no reason to implement these status bits.

Since we know dwc2_core_reset() is always called before
dwc2_get_hwparams() and we know dwc2_core_reset() should have set
GUSBCFG_FORCEHOSTMODE whenever hsotg->dr_mode == USB_DR_MODE_HOST, we
can just check hsotg->dr_mode to decide that we can skip the delays in

UPSTREAM: usb: dwc2: Avoid double-reset at boot time

In (usb: dwc2: reset dwc2 core before dwc2_get_hwparams()) we added an
extra reset to the probe path for the dwc2 USB controllers.  This
allowed proper detection of parameters even if the firmware had already
used the USB part.

Unfortunately, this extra reset is quite slow and is affecting boot
speed.  We can avoid the double-reset by skipping the extra reset that
would happen just after the one we added.  Logic that explains why this
is safe:

* As of the CL mentioned above, we now always call dwc2_core_reset() in
  dwc2_driver_probe() before dwc2_hcd_init().

* The only caller of dwc2_hcd_init() is dwc2_driver_probe(), so we're
  guaranteed that dwc2_core_reset() was called before dwc2_hdc_init().

* dwc2_hdc_init() is the only caller that passes an irq other than -1 to
  dwc2_core_init().  Thus if dwc2_core_init() is called with an irq
  other than -1 we're guaranteed that dwc2_core_reset was called before
  dwc2_core_init().

...this allows us to remove the dwc2_core_reset() in dwc2_core_init() if
irq is not < 0.

Note that since "irq" wasn't used in the function dwc2_core_init()
anyway and since select_phy was always set at exactly the same times we
could avoid the reset, we remove "irq" and rename "select_phy" to
"initial_setup" and adjust the callers accordingly.

We initiate dwc2 usb controller in BIOS, dwc2_core_reset() should

UPSTREAM: usb: dwc2: Restore GUSBCFG in dwc2_get_hwparams()

Previously dwc2_get_hwparams() was changing GUSBCFG and not putting it
back the way it was (specifically it set and cleared FORCEHOSTMODE).
Since we want to move dwc2_core_reset() _before_ dwc2_get_hwparams() we
should make sure dwc2_get_hwparams() isn't messing with things in a
permanent way.

Since we're now looking at GUSBCFG, it's obvious that we shouldn't need
all the extra delays if FORCEHOSTMODE was already set.  This will avoid
some delays for any ports that have forced host mode.

usb: dwc3: add rockchip specific glue layer

Add rockchip specific glue layer to support USB3 Peripheral mode
and Host mode on rockchip platforms (e.g. rk3399).

The DesignWare USB3 integrated in rockchip SoCs is a configurable
IP Core which can be instantiated as Dual-Role Device (DRD), Host
Only (XHCI) and Peripheral Only configurations.

We use extcon notifier to manage usb cable detection and mode switch.
Enable DWC3 PM runtime auto suspend to allow core enter runtime_suspend
if USB cable is dettached. For host mode, it requires to keep whole
DWC3 controller in reset state to hold pipe power state in P2 before
initializing PHY. And it need to reconfigure USB PHY interface of DWC3
core after deassert DWC3 controller reset.

The current driver supports Host only and Peripheral Only well, for
now, we will add support for OTG after we have it all stabilized.

UPSTREAM: xhci: fix platform quirks overwrite regression in 4.7-rc1

commit b1c127ae990b ("usb: host: xhci: plat: make use of new methods in
xhci_plat_priv") sets xhci->quirks before calling xhci_gen_setup(), which
will overwrite them.

Don't overwite the quirks, just add the new ones

arm64: dts: rockchip: modify dwc3 properties for rk3399

We have merged dwc3 driver from upstream, and some properties
need to be modified according to upstream coding style.

usb: dwc3: add a quirk xhci_slow_suspend_quirk

On some xHCI controllers (e.g. Rockchip SoCs), which are
integrated in DWC3 IP, need an extraordinary delay to wait
for xHCI enter the Halted state(i.e. HCH in the USBSTS
register is '1'), especially if DWC3 is in DRD mode.

FROMLIST: usb: dwc3: rockchip: add devicetree bindings documentation

This patch adds the devicetree documentation required for Rockchip
USB3.0 core wrapper consisting of USB3.0 IP from Synopsys.

It supports DRD mode, and could operate in device mode (SS, HS, FS)
and host mode (SS, HS, FS, LS).
