Subject: [PATCH 0/3] usb: typec: ucsi: Ack connector change early
Date: Wed, 27 Mar 2024 23:45:51 +0100 [thread overview]
Message-ID: <20240327224554.1772525-1-lk@c--e.de> (raw)
As briefly discussed here
https://lore.kernel.org/lkml/Zf1XUrG1UbVJWzoz@kuha.fi.intel.com/
acknowledge connector change events along with the first command
in ucsi_handle_connector_change(). The connector lock should be
sufficient to protect the rest of the function and the partner
tasks.
This allows us to remove the Dell quirk in ucsi_acpi.c.
Additionally, this reduces the number of commands that are sent
with an un-acknowleged connector change event.
Christian A. Ehrhardt (3):
usb: typec: ucsi: Stop abuse of bit definitions from ucsi.h
usb: typec: ucsi: Never send a lone connector change ack
usb: typec: ucsi_acpi: Remove Dell quirk
