[PATCH 6.6 065/222] usb: typec: ucsi: add update_connector callback

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>

[ Upstream commit 62866465196228917f233aea68de73be6cdb9fae ]

Add a callback to allow glue drivers to update the connector before
registering corresponding power supply and Type-C port. In particular
this is useful if glue drivers want to touch the connector's Type-C
capabilities structure.
