Some devices like the Librem 5 have full hardware kill switches that cut
power to the device. Their state is indicated via gpio pin so the
drivers only purpose is to forward the current switch state to the
rfkill core.

This needs more work to go upstream.

This allows to trace the negotiated contract as sink. It's

This allows to signal the DP core when an alt mode got negotiated.  The
(not yet mainlne) cadence/mhdp driver uses this to enable DP only when
an alt mode got negotiated to save power on the Librem 5.

Don't immediately set the data role, only set it in response the
negotiated value notification from the tps6589x. Otherwise data role
switch fails for DRP.

We only use values cached from the IRQ instead of poking I2C all
the time.

The update is moved in a function that will become more useful in later
commits.

Instead of refetching power status cache it and only update it when a
change is signalled via irq. This simplifies tracing and adding more
supply properties in follow up patches.

Together with the PD status register this is vital for debugging power

The bq25892 shares the USB 2 DP/DM with the dwc3 disable the auto negotiation

When the USB DP/DM lines are connected to more than 1 part on the board we
should disable auto DP/DM.

This enables/disbles OTG via register too. This way we avoid having to
wait for the GPIO which can give timing problems if that happens later.

Drop charging enable/disable while at that since the IRQ handler
toggles this via `F_CONV_*` anyway.

When we're supplied by another supply adjust the input limit
to what the upstream supply can provide.

This reverts commit a2caa72f.

Using them as keys has several problems:

- the pressed state can trigger auto repeat in other parts of the stack
- userspace expects the switches to mean 'toggle' not 'indicate'. So
  flipping e.g. the wifi killswitch toggles airplane mode although it
  should indicate: hks engaged.

We don't need the status update unless it's plugged in.

With broken CC lines the cable sometimes shows as plugged in even when it
isn't. Look further into the status register to see if it is connected and
disable the STATUS interrupt to stop the irq storm.

This is the 5.9.16 stable release

Commit 66d3f246 removed always-on
marking from GPU regulator, which is great for power saving - however,
it introduces additional i2c0 traffic which can be deadly for devices
from the Dogwood batch.

To workaround the i2c0 shutdown issue on Dogwood, this commit marks
buck3 as always-on again - but only for Dogwood (r3).

It has to be done just once as part of POR init. Doing it at each boot
resets the gauge state, so it can't learn the battery characteristics
over time.

The new value isn't taken into account until a refresh is triggered.

It's supposed to be a read-only value maintained by the gauge.
