+Subject: usb: typec: tpcm: Fix issues with power being removed during reset
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+commit 69f89168b310878be82d7d97bc0d22068ad858c0 upstream.
+
+Since the merge of b717dfbf73e8 ("Revert "usb: typec: tcpm: fix
+cc role at port reset"") into mainline the LibreTech Renegade
+Elite/Firefly has died during boot, the main symptom observed in testing
+is a sudden stop in console output.  Gábor Stefanik identified in review
+that the patch would cause power to be removed from devices without
+batteries (like this board), observing that while the patch is correct
+according to the spec this appears to be an oversight in the spec.
+
+Given that the change makes previously working systems unusable let's
+revert it, there was some discussion of identifying systems that have
+alternative power and implementing the standards conforming behaviour in
+only that case.
+
+Fixes: b717dfbf73e8 ("Revert "usb: typec: tcpm: fix cc role at port reset"")
