Hi Linus,
Karol found two last minute nouveau fixes, they both fix crashes, the

The throtl_schedule_next_dispatch() will validate if the service queue

update_min_dispatch_time() will call throtl_rb_first(), which will

Since start_boottime of processes are seconds since boottime and the
boottime stamp is now shifted according to the timens offset, the

Hi,
Made two changes:
1. Added "additionalProperties: false" as suggested by Rob Herring in
https://lore.kernel.org/linux-usb/20201005144618.GA154206@bogus/
2. Removed FRS dts binding constants to address Rob Herring's comment in
https://lore.kernel.org/linux-usb/20201006182940.GA2574941@bogus/
Occasionally, POWER_STATUS.sourcing_vbus takes a while to clear after
writing to MAX_BUCK_BOOST_OP register. This causes vbus to turn back
on while disconnecting the sink. Overcome this issue by writing into
MAX_BUCK_BOOST_OP during frs while sourcing vbu, instead of always
into the register whene
New source's current capability is now defined as string based
device tree property through new-source-frs-typec-current.
Refactor tcpm code to parse new-source-frs-typec-current and
infer local port's new source current capability during frs.

TCPCI spec allows TCPC hardware to autonomously discharge the vbus
capacitance upon disconnect. The expectation is that the TCPM enables
AutoDischargeDisconnect while entering SNK/SRC_ATTACHED states. Hardware
then automously discharges vbus when the vbus falls below a certain
threshold i.e. VBUS_S
PD 3.0 spec defines a new mechanism for power role swap called
Fast role swap. This change enables TCPM to support FRS when
acting as sink.
Once the explicit contract is negotiated, sink port is
expected to query the source port for sink caps to
determine whether the source is FRS capable.

The dependency should be just USB_ROLE_SWITCH, instead

This silences a static checker warning due to the unusual macro
construction of EXPECT_*() by adding explicit {}s around the enclosing
