them in read-only memory.

Because of a couple "quirks" it seems wiser to bind
these controllers to the same driver that DT is using

driver with PNP0D40.

process_madvise currently requires ptrace attach capability.
PTRACE_MODE_ATTACH gives one process complete control over another
process. It effectively removes the security boundary between the
two processes (in one direction). Granting ptrace attach capability
even to a system process is

MHI specification shows a state machine with support for STOP channel command
and the validity of certain state transitions. MHI host currently does not
provide any mechanism to stop a channel and restart it without resetting it.
There are also times when the device moves on to a different
Improve the channel handling state machine such that all commands
go through a common function and validation process to ensure
that the state machine is not violated in any way and adheres to
the MHI specification.

The mhi_prepare_for_transfer() and mhi_unprepare_from_transfer()
APIs could use better explanation, especially with the addition
of two new APIs to start and stop the transfers on channels. Add
better set of information for those APIs.

A client can attempt to unprepare certain channels for transfer even
after the execution environment they are supposed to run in has changed.
In the event that happens, the device need not be notified of the reset
and the host can proceed with clean up for the channel context and
memory allocated
When clearing the channel context, calling mhi_free_coherent()
more than once can result in kernel warnings such as "trying to
free invalid coherent area". Prevent extra work by adding a check
to skip calling mhi_deinit_chan_ctxt() if the client driver has
already disabled the channels.
When clearing up the channel context after client drivers are
done using channels, the configuration is currently not being
reset entirely. Ensure this is done to appropriately handle
issues where clients unaware of the context state end up calling
functions which expect a context.

The __mhi_unprepare_channel() API does not require the __ prefix.
Get rid of it and make the internal function consistent with the
other function names.

Some MHI client drivers may want to request a pause or halt of
data transfer activity on their channels. Support for this does
not exist and must be introduced, wherein the channel context is
not reset or cleared but only the STOP channel command is issued.
This would need to be paired with an API
If a channel was explicitly stopped but not reset, allow it to
move to a disabled state so that the channel context can be
cleaned up after a driver remove is issued. Since the channel
remained in stopped state, its context on the device is not
cleared. Allow this move if a client driver module is
Add support to allow sending the STOP channel command. If a
client driver would like to STOP a channel and have the device
retain the channel context instead of issuing a RESET to it and
clearing the context, this would provide support for it after
the ability to send this command is exposed to
