We need the USB/Thunderbolt fixes in here for other patches to be on top
of.

For UTMI+ PHY, according to programming guide, first should be set
PMUACTV bit then STOPPCLK bit. Otherwise, when the device issues
Remote Wakeup, then host notices disconnect instead.
For ULPI PHY, above mentioned bits must be set in reversed order:
STOPPCLK then PMUACTV.

On some SoC platforms, in shutdown stage, most components' power is cut
off, but there's still power supply to the so called always-on
domain, so if the dwc2's regulator is from the always-on domain, we
need to explicitly disable it to save power.

Disable platform lowlevel hw resources such as phy, clock and
regulators etc. in device shutdown hook to reduce non-necessary power
consumption when the platform enters shutdown stage.

As the wildcard name is dropped and favor new compatible string
which match a real SoC, and it is not used for any board at now.

Rename it to sophgo,cv1800b-usb to match the binding change.

Use the function usb_endpoint_type() rather than constants.
The Coccinelle semantic patch is as follows:

@@ struct usb_endpoint_descriptor *epd; @@

- (epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\))
+ usb_endpoint_type(epd)

It is possible that the gadget will be disabled, while the udc is
suspended. When enabling the udc in that case, the clock gating
will not be enabled again. Leaving the phy unclocked. Even when the
udc is not enabled, connecting this powered but not clocked phy leads
to enumeration errors on the host side.

To ensure that the clock gating will be in an valid state, we ensure
that the clock gating will be enabled before stopping the udc.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

According to the dt-bindings there are some platforms, which have a
dedicated USB power domain for DWC2 IP core supply. If the power domain
is switched off during system suspend then all USB register will lose
their settings.

Use GUSBCFG_TOUTCAL as a canary to detect that the power domain has
been powered off during suspend. Since the GOTGCTL_CURMODE_HOST doesn't
match on all platform with the current mode, additionally backup
GINTSTS. This works reliable to decide which registers should be
restored.
