Subject: [PATCH v1 0/2] usb: typec: ucsi: Recover from CrOS EC sysjump
Date: Tue, 4 Feb 2025 02:45:57 +0000 [thread overview]
Message-ID: <20250204024600.4138776-1-jthies@google.com> (raw)
An EC sysjump can break communication with the cros_ec_ucsi driver by
clearing any previously enabled notifications. This updates the
cros_ec_ucsi driver to monitor for PD initialization events from the EC
and re-enable notifications by treating the init event as a system
resume.

platform/chrome: add PD_EVENT_INIT bit definition
usb: typec: ucsi: resume work after EC init
