typec: tcpm: fusb302: Resolve out of order messaging events

2017-11-28T14:08:43+00:00

The expectation in the FUSB302 driver is that a TX_SUCCESS event
should occur after a message has been sent, but before a GCRCSENT
event is raised to indicate successful receipt of a message from
the partner. However in some circumstances it is possible to see
the hardware raise a GCRCSENT event before a TX_SUCCESS event
is raised. The upshot of this is that the GCRCSENT handling portion
of code ends up reporting the GoodCRC message to TCPM because the
TX_SUCCESS event hasn't yet arrived to trigger a consumption of it.
When TX_SUCCESS is then raised by the chip it ends up consuming the
actual message that was meant for TCPM, and this incorrect sequence
results in a hard reset from TCPM.

To avoid this problem, this commit updates the message reading
code to check whether a GoodCRC message was received or not. Based
on this check it will either report that the previous transmission
has completed or it will pass the msg data to TCPM for futher
processing. This way the incorrect ordering of the events no longer
matters.

typec: fusb302: Use dev_err during probe

2017-11-28T14:08:43+00:00

If probe fails, fusb302_debugfs_exit is called making it impossible
to view any logs so use normal dev_err for any error messages during
probe.

USB: typec: Remove remaining redundant license text

2017-11-07T14:53:48+00:00

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

USB: typec: add SPDX identifiers to some files

2017-11-07T14:53:48+00:00

Due to these typec files being moved into the drivers/usb/ directory in
this tree, they missed the larger "add SPDX tags to all files" work.  So
add the correct SPDX license tag, based on the license text in the file
itself.

The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

USB: add SPDX identifiers to all remaining Makefiles

2017-11-07T14:53:48+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

This updates the remaining drivers/usb/*Makefile* that were missing SPDX
identifiers.  They all get the following identifier:
	SPDX-License-Identifier: GPL-2.0

The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

The driver is in good enough shape to be moved out of staging.
